At cold start-up, the engine rattles loudly for about two seconds. The possible cause could be the variable valve timing control (VTC) actuator is defective. Replace the VTC actuator. This procedure does not require the complete removal of the cam chain and associated parts, so repair time is shorter.
- Honda has determined the cause to be a faulty variable valve timing control (VTEC) actuator. The rattle begins at cold start and sounds for about 2-seconds. The rattle may be intermittent and occurs usually when the engine has been off for 6-8 hours 3) Remove the throttle body (you can leave the coolant lines attached)
Why does my car make a rattling noise when its cold?
if you have a high-mileage vehicle with a worn engine, the pistons may fit in the cylinders very loosely. during a cold start, this may show up as a rattling noise. it typically goes away once the pistons expand from the heat of the engine.
Why does my Honda make a rattling noise?
The most common reasons a Honda Accord has a rattling noise are the ball joints, struts or strut mount, or a problem with the sway bar links.
What happens when VTC actuator goes bad?
The bad VTC causes a drag on the timing chain every time it grinds at start-up. Over time that small drag stresses the timing chain TENSIONER, until it eventually fails. With the timing chain tensioner no longer keeping the chain at constant tension a skipped or broken chain is just a question of time.
What causes engine rattle on startup?
Oil drain-back is a very common cause of knocks or mechanical noise during engine startup. When this valve does not seal properly or is not present, as in some cheaper filters, then your oil pump must pump the oil through all the sensitive parts of your engine every time you start your car.
How do you fix a cold start rattle?
A loud rattle type noise may be noted from the engine after a cold start. This can be caused by a faulty valve timing control actuator. Replacing the failed actuator will commonly correct this noise issue.
Why does my car sound like it’s rattling?
The rattling noise means that something isn’t right with the way your wheels are attached to the car. For example, a lug nut may have come loose and started rattling as the wheel turned around. Have your tires and wheels checked as soon as possible.
Why does my Honda Accord rattle when I start it?
At cold start-up, the engine rattles loudly for about two seconds. The possible cause could be the variable valve timing control (VTC) actuator is defective. Replace the VTC actuator.
Why does my car make noise when idling?
Loud idling is usually caused by issues with cylinder compression. When there are problems with cylinder compression, you get an uneven fuel-air ratio. As a result, combustion becomes unusual. Having higher pressure inside the cylinder will result in loud idling noise.
Why does my car sound like a tractor when idling?
When your smooth-running car or truck suddenly sounds like an angry tractor, chances are good that something within the exhaust system is to blame. The problem could be a broken exhaust manifold, or it could be farther downstream in the exhaust system’s pipes and its connection to the muffler.
How much does it cost to replace a VTC actuator?
Replacing one should cost about $20 to $40 in labor and $180 to $250 in parts depending on the cost of labor and parts in Your area. That gives You a total price range of $200 to $290 for the job. The VTC actuator in Your Honda has the job of keeping the intake valve timing accurate.
What is VTC actuator Honda?
What does the VTC Actuator do and do I need to fix it? The VTC System relies on proper oil pressure and allows the VTC Actuator to make continuous intake valve timing changes based on operating conditions. Intake valve timing is optimized to allow the engine to produce maximum power.

If you are reading this service bulletin on SIS and your computer is equipped with sound, you may listen to a sample of the engine’s rattling by clicking on the image below.
- Allowing the engine oil to drain from the VTC system for at least 6 hours will allow the oil to be more effective. As soon as you start the engine, pay attention for a loud rattling.
Do you notice a loud enginerattle that lasts around 2 seconds when the engine first starts up? In this case, proceed to the REPAIR PROCEDURENOIf you hear a different noise, proceed with the standard troubleshooting procedure. If you do not hear an unexpected noise, ask the client for further details and, if necessary, proceed with the standard troubleshooting process.
This technique is written in outline style, and you may use it as a checklist for the repair as well as a reference guide. If you want further information, please consult the service information for the following procedures:
- Removal of the cylinder headcover
- Installation of the cylinder headcover
- Adjustment of the valve clearance
- Remove the frame (strut) brace (if it is provided)
- Remove the wheels. Remove the engine cover from the vehicle. Remove the ignition coil cover and the ignition coils from their sockets and set them aside.
- Remove the engine oil dipstick, then separate the breather hose and the brake booster vacuum pipe from the cylinder headcover
- Then replace the dipstick.
- Removing the two bolts that hold the EVAPcanister purge valve bracket to the cylinder head is necessary. Unscrew and remove the cylinder headcover. Lift the car using a forklift
- Turn the frontwheels or remove the right front wheel, whichever is appropriate. To gain access to the crankshaft pulley, remove the splash shield from the engine. Remove the lid for the camshaft auto-tensioner (chain case). Using a clockwise rotation of the crankshaft, bring No. 1 cylinder to top dead center (TDC). To compress the auto-tensioner, rotate the crankshaft in the anticlockwise direction. Place a 1.2 mm (0.05 in)-diameter stopper (lock pin) in the hole in the lock and auto-tensioner and tighten the mechanism.
- Lower the car and rotate the crankshaft counterclockwise to TDC No. 1 cylinder. Identify the timing chain at the punchmarks on the exhaust camshaft sprocket and the variable timing controller (VTC). Wire ties should be used to attach the chain to the sprocket.
- Loosen the camshaft holding bolts by turning them two turns at a time, in succession
- Remove the five camshaft holders from their positions. Place them on a clean surface in the same sequence and position that they were removed from the cylinder head
- Then set them aside. Carefully tilt up the end of the intake camshaft until there is enough slack for an aid to remove the chain off the VTC actuator teeth, then reverse the process. Remove the intake camshaft/VTC actuator assembly with the assistance of the helper, who will maintain a mild strain on the chain. Prepare a clean, cushioned workbench and place the camshaft/VTC actuator assembly on it
- A wire or zip tie should be used to secure the timing chain to the A/C compressor hose to prevent it from dropping into the front cover. Remove the VTC actuator mounting bolt from the camshaft while an aid keeps the camshaft firm with an open-end wrench on the workbench. Next, separate the VTC actuator from the camshaft with an open-end wrench. Remove the VTC actuator and throw it away.
- Make certain that the new VTC actuator is in the unlocked position before installing it.
- It is not necessary to press the new, unlockedVTC actuator onto the camshaft during installation. Once installed, gently spin the VTC actuator counterclockwise until it engages the camshaft’s locator pin, with the VTC actuator facing you. The VTC actuator will not lock if it is inserted and rotated in this manner. Clean engine oil should be applied to the mounting bolt threads before installing the mounting bolt finger tight
- Step 28 should be followed if the new VTC actuator is unlocked after it has been installed on the camshaft. If the VTC actuator remains locked after it has been installed on the camshaft, go to step 25.
- Clean engine oil should be applied to the mounting bolt thread before installing the mounting bolt on the actuator finger tight
- This will free a lockedVTC actuator. Cover the pressure port1 on the camshaft with many layers of electrical tape to prevent it from being damaged. As illustrated, use a wire tie to hold the tape in place.
- Apply pressurized air to pressure port 2 to make it work. The VTC actuator should be rotated manually to the unlock position while compressed air is being delivered to pressure port2.
- Hold the camshaft/VTC actuator unit in place on the cushioned workstation with an open-end wrench while a helper does the same. The mounting bolt should be torqued to 113 Nm (83 lb-ft) with a torque wrench.
NOTE: Take care not to scratch or damage the camshaft during the installation process. Aside from that, do not use an impactwrench to tighten the mounting bolt since doing so can cause internal damage to the VTC actuator housing as well as the vanes and lockpin.
- After the mounting bolt has been torqued, spin the VTC actuator until it is in the locked position. As an assistant maintains a little stress on the chain, remove the wire ties from the chain. In order for the chain to be able to glide over the actuator’s teeth, slide the camshaft/VTC actuator in at an angle. In order for the markings you created on the chain to match up with the punchmarks on the exhaust camshaft sprocket and VTC actuator, you must first align them.
- Engine oil should be applied to the journals and caps of both camshafts. Lower the camshaft/VTC actuator assembly onto the journals of the camshaft assembly. Install the camshaft holders in their respective positions. Apply two twists at a time to tighten them, starting in the centre and working your way outward, following the numbered sequence
- Remove the lock pin from the auto-tensioner and set it aside. The crankshaft should be rotated two full rounds in the direction of engine rotation (clockwise) before coming to a halt at the TDC point. Check to verify that both camshafts are aligned as illustrated in step 15
- Inspection of the cylinder block should be performed to ensure that the timing chain is correctly riding on its guide and has not slid backward behind the guide in the block. If this is the case, readjust the chain as necessary. The previous sealant should be removed and dried before resealing, and then the auto-tensioner(chain case) cover should be reinstalled.
WARNING: Allow 30 minutes before adding oil (if necessary), and then allow 3 hours before turning on the engine.
- A tappet adjuster can be used to check the valve clearance. If necessary, make adjustments.
Intake: 0.21 mm (0.008 in) to 0.25 mm (0.010 in) Exhaust: 0.25 mm (0.010 mm) to 0.29 mm (0.011 in)
- To torque the locknuts after making the necessary changes, use a tappet locknutwrench.
14 Nm for the intake and exhaust (10 lb-ft)
- Elevate the car and replace the splash shield. Straighten the wheels or replace the right front wheel (if it has been removed). Reduce the vehicle’s height
- Inspect the sparkplug seals for signs of wear. If any of the seals are damaged, they should be replaced. NOTE: Make sure the head cover gasket is in good condition. If necessary, replace the item. The head cover gasket should be installed in the groove. Removing the complete liquid gasket from the chain case and No. 5 rocker shaft holder is recommended. Using a cleanshop cloth, wipe off the areas of the head cover that come into touch
- Reinstall the cylinder headcover, tightening the bolts in three stages as you go to ensure a secure fit. The last step is to torque all bolts in a sequential manner to 12 Nm (8.7 lb-ft)
- Replacing and reconnecting the EVAPcanister purge valvebracket, the engine oil dipstick, and the breather hose and the brake booster vacuum hose are all recommended.
- Reinstall the ignition coils as well as the ignition coil cover if necessary.
- Reinstall the engine cover if necessary. Replace the frame (strut) brace if it has been removed (if equipped). Tighten the bolts to a torque of 22 Nm (16 lb-ft)

Symptom: When the engine is first started from a cold start, it rattles noisily for approximately 2 seconds. There is no end to the number of Honda owners who come across my initial VTC Actuator Problem post, read it, and then leave a comment. This issue, known as ‘Engine Rattles at Cold Startup’/VTC Actuator, affected all 2008-2012 Honda Accords with 2.4L 4-cylinder engines, as well as all 2007-2014 Honda CR-Vs and all 2WD vehicles in general. Honda Crosstours from 2012 to 2015. The VIN of your Honda CR-V or Crosstour should be checked if you possess a 2013 model.
The cars shown in the chart below are those that were impacted by the current TSB 09-010, which was issued on February 25th, 2017.

Engine Rattles at Cold Startup TSB16-012
Symptom: When the engine is first started from a cold start, it rattles noisily for approximately 2 seconds. This is a temporary condition that happens when the outdoor temperature is below 40° Fahrenheit. Honda TSB 06-012 ‘Engine Rattles When Cold Start Is Initiated’ (My eReport incorporates the most latest TSB version 2, which was released on February 23, 2017.) If you own one of the above-mentioned Accords, CR-Vs, or Crosstours, it is critical that you repair your VTC actuator* immediately in order to avoid a catastrophic engine failure and costly repairs.
I was and continue to be in the same state of mind.
Furthermore, there appears to be a significant association between ‘Engine Rattles at Cold Startup’ and ‘Sticking Piston Rings Resulting in Unusually High Engine Oil Consumption,’ which makes an already terrible situation even worse (TSB 12-087andTSB 12-089).
(You will need to perform the software update in order to be eligible for the extended warranty.) As a result, American Honda is extending the coverage of its warranty on the piston rings and pistons for the 2010-11 Honda CR-V 2WD and 4WD models for an additional eight years from the original date of purchase or 125,000 miles, whichever comes first.
- (This is in accordance with TSB 11-049) The Honda Accord automobiles manufactured in 2008, 2009, and 2010 (the ‘Class Vehicles’) are affected by a systemic design issue that allows oil to enter the engine’s combustion chamber during normal operation.
- VTC Actuator issues in Honda vehicles contribute to the vehicle’s high oil consumption.
- Honda was the target of a class action lawsuit that was filed in 2012.
- My Honda dealership sent me a letter, in August of 2015, informing me that they would be extending their guarantee on the engine cylinders and piston rings for an additional eight years from the date of purchase or 125,000 miles, whichever came first.
I’ve put together a full study on the subject, and I’m providing you with access to current TSB 09-010, which was published on February 25th, 2017. (Always check with your local Honda dealer to see if there are any new or updated TSBs.)
Sticking Rings Resulting in Unusually High Engine Oil ConsumptionTSB 12-087
In certain four-cylinder Accord coupe and sedan models from 2008 to 2011, as well as the CR-V SUV models from 2010 to 2011, Honda has discovered that oil consumption may become greater than usual in some models. Consumer Complaints1 (Consumer Reports) See a copy of the class action complaint that was filed against American Honda in this case. Take note of the likely causative factor number 4 that is mentioned on page 1: Alternatively, a weakness in Honda’s VTEC variable engine-timing system, which wrongly enables oil to flow into the engine’s combustion chamber, might be the source of the problem.
- Honda also offered extended warranties on some Honda Accords and CR-Vs to residents of Washington State, as well as to non-residents.
- (Accord owners should refer to Honda Service Bulletin 12-087, while CR-V owners should refer to Honda Service Bulletin 12-089) The following letter should have been delivered to your home if you owned a Honda Accord or Honda CR-V during the year 2015.

- Start the engine and keep an ear out for a jarring vibration.
- Remove the engine oil dipstick from the engine.
EVAP canister purge valve bracket bolts are removed by removing the two bolts that hold the bracket to the cylinder head.
Remove the valve cover from the engine.
Place the car on a lift and raise it.
Turn the front wheels or remove the right front wheel, whichever is most convenient.
Turn the crankshaft in the opposite direction of rotation to compress the auto-tensioner.
The crankshaft should be rotated in a clockwise direction to the TDC number one cylinder.
Lower the car to the ground.
A wire tie should be used to attach the chain to the sprocket.
Remove the five camshaft holders from their positions.
Then, with care, raise one end of the intake camshaft until there is enough slack for an aid to remove the chain off the VTC actuator teeth (step 20).
Place the camshaft/VTC actuator assembly on a clean, lightly cushioned workbench to protect it from damage.
Use a wire or zip tie to secure the timing chain to the A/C compressor line to prevent it from dropping into the front cover.
Remove the malfunctioning actuator from the system.
Before attempting to install the replacement VTC actuator, be certain that it is in the unlocked state.
Slide the new, unlocked VTC actuator onto the camshaft without forcing it into place.
The VTC actuator will not lock when it is mounted and rotated in this manner.
If you have a locked VTC actuator, you can unlock it by applying clean engine oil to the mounting bolt threads and then installing the mounting bolt on the actuator with your fingers finger tight.
As illustrated, use a zip tie to hold the tape in place.
Apply compressed air to pressure port2 to create pressure.
Check to see that the actuator has been shifted to the unlock position.
Using an open-end wrench, have an aide keep the camshaft/VTC actuator assembly stable on the cushioned workstation throughout the next step.
The VTC actuator should now be rotated to its locked position once the mounting bolt has been torqued.
As an assistant maintains a little stress on the chain, remove the wire ties from the chain.
Align the punch marks on the exhaust camshaft sprocket and the VTC actuator with the markings you produced on the chain in Step 34 of the process.
Lubricate the journals and caps of both camshafts with engine oil.
Twice at a time, beginning in the centre and working your way outward, following the numbered order.
Using the crankshaft, rotate it two complete rounds in the direction of the engine’s rotation (clockwise), then stop at the white TDC mark on the crankshaft.
Visually check inside the cylinder block to ensure that the timing chain is properly riding on its guide and has not slid behind the guide inside the block.
removing the old sealant, drying it well, resealing it, and reinstalling the auto4ensioner (chain case) cover NOTE: Allow 30 minutes before adding oil, if necessary, and allow 3 hours before starting the engine to ensure proper operation.
Using a tappet adjuster, check the valve clearance and make any necessary adjustments.
Raise the vehicle to its full height.
Replace the splash shield with a new one.
48 Replace the cylinder head cover, retightening the bolts in three stages.
by turning them one at a time (8.7 lb-ft).
Replace the bracket that holds the EVAP canister purge valve.
Reinstall the engine oil dipstick and reattach the breather pipe and the brake booster vacuum hose to the engine.
51. Replace the engine cover in its original location. 52. Replace the brace that supports the frame (strut) (if equipped). Tighten the bolts to a torque of 22 N.m (16 lb-ft). Rick Muscoplat’s 2016 Rick Muscoplat’s Rick Muscoplat posted a blog entry on

In order to solve the Honda rattles when cold situation on the cars mentioned below that have the 2.4L engine, Honda has issued a service bulletin09-010 to dealers. For the following Honda Accord models, the service bulletin to remedy the rattling condition is applicable: Accord L4 (all) (2008-12) all models from 2007 through 2012 cr-v When starting a cold engine, according to Honda, there is a loud rattling that lasts around 2-seconds. After investigating, Honda discovered that the variable valve timing control actuator was not working properly.
- Allow the engine to idle for at least 6 hours to allow for the oil to drain from the VTC system.
- When you begin to hear a loud rattle, turn off the engine and wait.
- Third, take down the framework or brace (if applicable) (if equipped).
- Pull the engine oil dipstick out of the engine oil filler neck.
- The two bolts that hold the EVAP canister purge valve bracket to the cylinder head should be removed as part of step 7.
Install a lift to raise the car.
To gain access to the crankshaft pulley, first remove the splash shield from the engine.
To compress the auto-tensioner, rotate the crankshaft counterclockwise.
With a wire tie, attach the chain to the sprocket.
The five camshaft holders should be removed at this point (19).
Install a light tension on the chain while removing the intake camshaft/VTC actuator assembly with the assistance of a third person.
To remove the VTC actuator from the camshaft, get an assistant to hold the camshaft steady with an open-end wrench while you remove the actuator mounting bolt on the workbench.
Ensure that the new VTC actuator is in the unlocked position prior to putting it into place.
Upon installation, carefully rotate the VTC actuator counterclockwise until it engages with the locator pin on the cam shaft, with the VTC actuator pointing in your direction.
Place a small amount of clean engine oil on the threads of the mounting bolt and screw it into place with your finger tight.
With several wraps of electrical tape, seal the pressure port1 on the camshaft.
Pressurize port 2 with compressed air (step 29).
Complete the VTC unlock procedure while air pressure is applied to pressure port2.
Remove all electrical tape and adhesive residue from the surface afterward.
Tighten the mounting bolt to 113 N.m.
The VTC actuator should now be rotated to its locked position after the mounting bolt has been torqued.
As an assistant maintains a light tension on the chain, remove the wire ties that were used.
Align the punch marks on the exhaust camshaft sprocket and the VTC actuator with the marks you made on the chain in step 34.
Lubricate the journals and caps on both camshafts with engine oil.
Close them down two turns at a time, starting in the middle and working your way outward, following the numbered sequence on the package.
Using the crankshaft, rotate it two full turns in the direction of the engine’s rotation (clockwise), stopping at the white TDC mark.
As a result, the chain should be realigned if necessary.
41 Please allow 30 minutes before adding any additional oil and 3 hours before starting the engine.
With a tappet adjuster, check and make any necessary adjustments to the valve clearance.
Measurements for the exhaust: 0.25 to 0.29 millimeters (0.010 to 0.011 inches).
Replacing or reinstalling the splash shield Repair or re-install the right front wheel if the wheels are bent (if removed).
In the final step, tighten all bolts to 12 N.m.
EVAP canister purge valve bracket should be installed again.
51. Replace the engine cover with its original position. Install the frame (strut) brace in its original location (if equipped). Using a torque wrench, tighten the bolts to 22 Nm (16 lb-ft). Rick Muscoplat was born in the year 2016. Rick Muscoplat wrote a post on
2.4L Engine noise on cold start-up, CRV AND Accord
Honda, I am writing to express my gratitude for the opportunity to work with you. I recently purchased a 2014 Honda CRV EX and am really pleased with it. This is my family’s fourth Honda car and the fifth Honda product that they have purchased. My mother has also acquired a 2014 Honda CRV EX-L, which is her third Honda vehicle. Because of your reputation for dependability and quality control, I decided to acquire another Honda. You also have a reputation for going above and beyond to assist your consumers in any manner that you can, which I much appreciate.
- Find the phrase ‘2012 Honda CRV, Cold start sounds’ on You Tube and listen to the sound you will be able to identify exactly what I’m referring about.
- A metal-on-metal sound, similar to a grinding noise, or what sounds like the timing chain contacting the valve cover, to me, is being heard.
- He informed me that his own 2013 Accord 2.4l, as well as the dealership’s general manager’s new Accord, performs this function!
- This is, without a doubt, a well-known issue.
- I have over 23 years of mechanical expertise working on a wide range of makes and models, and I can assure you that the noise is NOT typical in this situation.
- Only if you crank the car with the doors open can you hear it (I had to warm the car after a snow event, which was the first time I heard it), thus the vast majority of people are probably completely oblivious that it is even happening.
- How has Honda avoided addressing the fundamental cause of the problem?
- I find it difficult to accept that, after all of your engineering and R & D efforts, the source of this noise has not been found and a solution proposed.
- I’m not intimately aware with the 2.4L engine, so I’m not sure what issue it would refer to, but maybe it will provide a starting point for your engine’s engineers.
- In order to preserve Honda’s reputation for quality and dependability, the company must devote the resources necessary to determine the root cause of the problem and implement a recall for all vehicles that are impacted.
I truly enjoy my CRV, but after spending more than $26,000 on a new vehicle, having one that produces engine noise simply because it is chilly outside when you first turn it on is completely unacceptable. Thank you very much.
Engine rattle when cold start and placed in reverse.
I realize there have been several discussions regarding this issue, but I’m just checking in to see if there has been a final answer. My 2010 with 117,000 miles makes a rattling sound when it is initially started in the morning and when it is placed in reverse. The sound is similar to that of an engine cover or belt cover that has come loose and is reverberating. It’s the same problem whether it’s summer or winter. Having a problem has been there since the entire timed task was completed at 101,000 seconds.
- All of the timing components were made by Aisen, and the engine mount was made by Honda.
- When the engine is warmed up, the noise disappears as well.
- There have been several discussions regarding the timing chain tensioner, but it is my view that a malfunctioning tensioner would create noise whether the engine was cold or hot, in park or in gear, and that the noise would be the same regardless of the condition of the engine.
- Some of the entries indicated difficulties with the power steering reservoir, pump, and oring.
- Perhaps I made a mistake when I placed the engine mount?
- Thank you for your advice.
- The same thing occurred to me after changing all of the pulleys, tensioner, timing belt, and other components.
- I replaced the belt with an original Honda belt and the problem was resolved.
Loud Rattle On Cold Start Up & While Driving
On November 16, 2013, at 9:36 p.m., Date of joining: April 2012 Tinley Park, Illinois is the location. Number of posts: ten On a cold start up, there is a loud rattle. When You’re Driving My 2009 Honda Accord with a 2.4-liter engine has a loud rattling when it is first started up. It was on this forum that I discovered the details of TSB 09-010. This has been going on for more than a year, and I had been waiting for the problem to worsen in order for my Honda dealer to be able to identify it more readily.
- When I first start driving, the sound is present until the vehicle goes into second gear, at which point the sound disappears.
- It appears to be present exclusively at very slow speeds.
- They phoned me about midday to say that they didn’t notice any noise when the engine was first started.
- Originally, it was amended in January of this year, when it had reached the 15 percent mark.
- He phoned me back a few hours later and stated that he had not noticed any noises during the start-up or while driving the vehicle.
- I was surprised.
- My question is whether being one quart low on fuel may have been the cause of this, and whether there is perhaps a problem with the valves.
Any assistance you can provide me would be greatly appreciated. (I phoned the service adviser and left a message for him, informing him about TSB 09-010, which he acknowledged.) Please accept my apologies for the lengthy post. Thank you very much, Tim.

Tastypotato: Can you tell me how many miles you have on it and what year it is? TSB 16-088 is a technical service bulletin. The article, titled ‘Engine Rattles on Cold Startup,’ details the procedure for replacing the VTC actuator step by step. It is not a straightforward technique for a do-it-yourselfer, but it is doable. For about seventy thousand kilometers, I had to put up with those terrible rattles. The automobile was scrapped after 80k miles, but the engine was still going strong. The rattles did not do any harm, and despite the fact that they sounded dreadful, they did not become any worse.
However, this never occurs.
This makes sense because the rattles do not cause any physical harm to the user.
I’ve also heard that the Hyundai that my coworker drives does this every time she gets in her car to drive back home.
However, it should be noted that the pdf also includes a list of additional miscellaneous components that should be changed at the same time.
I now own a 2016 Fit, and I haven’t had any issues with rattles with my vehicle.
