Remove car AC clutch? (Perfect answer)

  • If you need to remove car AC clutch from your compressor, the pulley bearing, or the front seal, you’ll need to remove the clutch. You’ll need a clutch holding tool and a clutch removal and installation kit. This kit has everything you need to pull the front clutch disc off the shaft and re-install it.

Can you disconnect AC clutch?

Yes if the clutch is disengaged on the AC compressor which it usually is, leave it off and it won’t get engaged.

Can you replace AC clutch without removing compressor?

Yes you can just replace the clutch pulley on the a/c compressor. The issue that you may have is the pulley bearing seized up and may have spun on the front of the compressor nose cone and will damage it. You may need to replace compressor.

Can you turn the AC clutch by hand?

Yes, the clutch does not move “normally” until the a/c is activated and then it does spin with the pulley. However the clutch assy and compressor are mounted on the same keyed shaft and turn together ALWAYS. Therefore if you turn the clutch assy by any means it will be turning the compressor.

What happens if I unplug my AC compressor?

The a/c compressor cannot be permanently removed because the serpentine belt powers all accessories, including the compressor, in one “circuit”. If you were to take the compressor out you won’t be able to install the serpentine belt because a key component will just not be there.

Can you remove AC compressor?

Replacing an AC compressor is almost as simple as replacing any other accessory on your motor like the alternator or power steering pump. The biggest difference is that before you remove the actual compressor you have to remove the refrigerant lines connect to it.

Is it better to replace AC clutch or compressor?

The primary reason to replace an entire A/C compressor and clutch assembly is for better long-term reliability. The AC clutch pulley might be what needs replacement, but it’s likely to have done some damage to the compressor on its way out.

How much does it cost to replace an AC clutch?

Between $610 and $664 is the average cost for an AC compressor clutch replacement. Labor costs are between $184 and $232 while parts are between $426 and $432.

How do I know if my AC compressor or clutch is bad?

Have your assistant turn on the AC controls to maximum. Listen for any internal buzzing or clicking from the clutch. If the clutch fails to engage and spin, but you hear electrical buzzing or clicks inside, it indicates an internal clutch short. Listen for excessive bearing noise coming from the clutch or compressor.

Why is my AC clutch not engaging?

Why AC clutch won’t engage If the clutch doesn’t engage, the problem could be a blown fuse, an open in the wire to the clutch coil, a bad clutch coil, a poor ground, a low pressure switch lockout, or even a bad engine coolant temperature switch.

Is AC clutch supposed to spin freely?

Most AC clutches are designed to spin freely when disengaged, and also with the pulley and compressor when those are engaged. If the clutch spins freely at all times, and the compressor never comes on, then it may not be engaging and therefore needs to be replaced.

Will AC clutch engage with low Freon?

If the Freon levels are too low, the clutch will fail to engage which means there’s not enough refrigerant for the compressor to pressurize. In other words, your air conditioning system has nothing to work with!

Can you manually engage AC compressor clutch?

Unplug the single wire connector on the front side of the compressor. Take the fused jumper wire and connect its one end to that side of the wire connector that was connected to the compressor. It will supply the battery voltage to the compressor clutch, allowing it to engage manually.

Replacing The AC Compressor Clutch

The reason for a harsh idle might be due to a variety of reasons, as we have discussed above. In order to determine what codes have been activated, it is recommended that you examine the engine computer. They can assist your mechanic in determining the source of the problem and suggesting a remedy. The “usual suspects” are checked by your mechanic if the problem is not immediately apparent. Checks will be performed to ensure that the relevant electronic components are in proper working order, that the valves and sensors are clean and functional, that the hoses are not cracked or leaking, that the spark plugs and their wires are in good condition, that the air filter is in good condition, and so on and so forth.

You should be able to get your car back on the road as soon as the problem-causing elements have been repaired, cleaned, or otherwise addressed.

How to Replace an AC Compressor

To begin, what exactly does an air conditioning compressor do? It is most likely the most critical component of your air conditioning system, since it is responsible for ensuring the flow of refrigerant. So if yours is beginning to fail, you will notice the indicators, the most prevalent of which is air conditioning that is no longer as chilly as it used to be. You may also hear a great deal of noise, such as chattering bearings or a screeching belt, while driving (if the compressor is seized up).

While changing an air conditioning compressor may feel like a life or death situation, especially in the middle of heat, it isn’t the most difficult task.

Don’t forget to put on your safety glasses and latex gloves before getting started!

Estimated Time to Completion 3 to 5 hours

  1. The purpose of an air conditioning compressor is first explained. Your air conditioning system’s expansion valve is possibly the most critical component, as it ensures that refrigerant flows freely. You’ll notice the indicators if yours is beginning to fail, the most prevalent of which is air conditioning that is no longer as chilly as it used to be. Noises such as chattering bearings or a screeching belt may also be heard, as well as a lot of noise (if the compressor is seized up). Also possible is that the compressor’s clutch may not engage and will just cycle off and on indefinitely. Replacement of air conditioning compressors, while it may feel like a life or death situation, especially in the midst of heat, is not a difficult procedure. You may read more about it here.

How to Repair the AC Clutch

On January 13, 2021, the information was most recently updated

Step 1

The most recent revision was made on January 13, 2021.

Step 2

Remove the clutch and look at the spacers on the shaft that are behind the clutch. They are required in order to properly gap the clutch, thus store them in a secure location to avoid losing them. Remove the snap-ring on the shaft that holds the pulley in place, then slide the pulley out of the shaft using your fingers.

Step 3

Before installing the shaft, be sure to properly clean it and all of the other components. Insert the replacement pulley and snap-ring into place, with the beveled edge of the snap-ring facing outward.

Step 4

Attach the clutch to the compressor shaft with one spacer and tighten the 6 mm bolt to ensure that it is properly attached.

Step 5

To verify correct clearance between the clutch and the pulley, place a feeler gauge between the two. If the clearance is not correct, the clutch plate should be removed and a new spacer installed. It is necessary to check the air gap in order for the clutch to engage correctly.

If the air gap and/or clearance are not accurately measured, your clutch may wear down more quickly than expected. The connector should be connected to the electromagnetic coil. References What You’ll Need to Get Started

  • Using a feeler gauge, check that there is adequate space between the clutch and the pulley. Removing the clutch plate and replacing it with another spacer will fix the problem. For proper engagement of the clutch, make sure the air gap is correct. Because of inaccurate air gap and/or clearance measurements, your clutch may wear down more quickly. The connector should be attached to the electromagnetic coil. References You’ll Need a Few Things.

Second gear Can the A/C compressor clutch be removed on vehicle? (or, partial AC removal)

Backstory – I just replaced all belts on my recently acquired 97 Montego.I had assumed that the alternator belt was shot (based on screaming on startup), but replaced both belts to be sure.The accessory (PS/AC) belt was TOAST.The ribs were almost totally gone, and what remained was just slipping along the pulleys, I’m pretty sure.AC hasn’t worked since I bought the car (Mid Jan), even with a bit of R134a to top it off to working low-side pressure.Fast forward – I’m a tank and a half past belt replacement, and my mileage at 1/2 tank ismuchlower than usual, despite the same routes driven.Adding to this is the fact that I have a nasty chirp from the a/c clutch at times, and there is still a (reduced) screech at some startups.I’m ready to bypass the AC compressor, but would like to leave as much in place as possible to not reduce resale value.By that I mean I would like to not leave open lines to invite oxidation / rust into the (pressurized) a/c lines.From experience, I know that one can’t quite get the PS-only belt to run with the compressor in place.Given the fact that I am pretty confident that the compressor (or just clutch) is dead, I’d like to remove the clutch, and leave the rest of the system intact.Is this possible?Barring that, does anyone have experience “capping” the refridgerant lines after removal of the compressor?If I can’t just pull the clutch, I would like to cover the ends of the lines in a hermetic manner, so I don’t rot the rest of the system.Any advice / experience would be appeciated!

Car air conditioner compressor clutch not engaging

Using the troubleshooting steps given here, you may determine if your car’s air conditioner compressor clutch is not engaging properly. The air conditioning compressor is engaged and disengaged by use of an electro-magnetic clutch, which is used by automobile manufacturers. The three components of the air conditioning compressor clutch in an automobile are as follows: When power is applied to the clutch coil, the magnetic field created by the current draws the clutch in and engages the compressor shaft.

  1. As a result, you should begin by evaluating whether or not the compressor clutch is operational.
  2. Then have a look at the compressor clutch from the front.
  3. If the only thing that is rotating is the pulley, there is an issue elsewhere in the system.
  4. In certain cars, the low pressure switch and the evaporator temperature sensor are used to control the compressor clutch relay, which is switched on and off.
  5. Remove the electrical connector from the clutch coil and set it aside.
  6. Use a digital voltmeter to check for battery voltage and good ground at the connector when the engine is running and the AC is set to the maximum setting.
  7. If the fuse is good, replace the compressor clutch relay.

Some automobile manufacturers use the PCM or ECM to trigger the relay control coil ground, while others do not.

When electricity is applied to other cars, it passes via the air conditioning switch and into the fuse, and then passes through the fuse, past the low pressure and evaporator temperature sensors, and into the clutch coil.

As a result, automakers include a low pressure switch in their vehicles, which prevents the compressor from functioning when the system is short on refrigerant.

However, if the system’s refrigerant level is too low, the clutch will not engage.


Even if you are successful in getting it to accept a charge, it is possible that you have already destroyed the compressor.

This will force the compressor to operate with insufficient oil, which may result in the compressor being destroyed.

Due to the fact that there is likely air and moisture in the system, the leak is significant and should be addressed.

After that, the system should be completely evacuated to ensure that all air has been removed before it can be recharged.

Adding extra refrigerant is possible without having to hot wire the low pressure switch and operate the compressor at full capacity.

In order to recharge the battery, connect it to the low pressure (suction) connector.

In addition, the DIY kit fitting will only attach to the low pressure port, not the high pressure.

To activate the radiator fans, turn the air conditioner up to its maximum setting.

Depending on whether your car is equipped with an orifice tube system, the refrigerant gas will pass through one of the open compressor reed valves before entering the condenser coil.

Because the compressor will not be functioning, there will be no pressure in the system.

Whenever a liquid enters the evaporator, it will boil and change back into a gas as long as the blower fan is operating.

Try starting the engine and inspecting the compressor to see what happens.

If this procedure does not work, you should take it to a professional.

Removing the AC Clutch?

You are currently using an out-of-date web browser. It is possible that this or other websites will not show correctly. You need either upgrade your browser or switch to another one. 1223Buick Lucerne Ownership2008 Buick Lucerne Ownership So I went on a search on the internet for a way to remove the aircon compressor clutch from my 2008 Lucerne. I came up with nothing. There’s nothing specific, but there’s a lot of material that belongs to the same family as it. I purchased a clutch removal tool package that included a variety of different equipment.

I was able to remove the bolt from the front of the air conditioning unit, but there are no threads to screw the removal tool into.

I don’t want to go into the room and start interrogating people.

Is this something anyone has done before, or does anyone know the secret?

I can’t stand the sound it’s making.

Oh, that’s right, it’s the 3.8 L9,6483,397113.

It certainly appears as though it should be delivered in this manner.

Everything about it is in stark contrast to what is being displayed elsewhere on the internet.

There are also no threads to grip onto with the tool since there are none.

When he pulled it off, I burst out laughing.

The next day, I’ll try my hand at it once more if necessary.

I was able to go back in there today.

I tried carefully peeling it from both sides, spraying it with lubricant in the thread region, tapping it, and then trying again.

That item is simply not budge-able at all.

The only thing that is holding me back is that while the ac is operational, the pulley is only making noise, which means there is a lot of room for error.

Due to the whining sounds, I don’t want to invest the money on a new compressor simply to be safe.

To be more specific, original equipment such as DENSO 4710714 or ACDELCO 1521517GM is required.

You must not use a gear puller on this specific clutch plate, or else you will completely damage the clutch plate.

The snap ring must be removed before the pulley can be removed in order to replace the bearing, as is obvious!

Otherwise, you will completely destroy all of the bearingcompressor seals!

Unfortunately, there was no luck.

The automobile did not have a salvage title, and it does not have a musty odor inside, but I am beginning to wonder whether it was submerged in water for an extended period of time.

Anyhow, a man on eBay has a clutch, pulley, and magneto for sale that has been reconditioned for less than what I have paid thus far on tools and other miscellaneous thingsamajobs.

Finally, I may just keep it operating for another 5 years and then replace it with something new.

Everything on it is functional, and it is in reasonably good condition for a 12-year-old vehicle, with the exception of some concealed corrosion.

Thank you very much for all of your assistance and recommendations!

I acquired an old compressor on the cheap so that I could investigate what was going on in the system.

The hole in the clutch is threaded, and it has a bigger diameter than the bolt on the input shaft, which I discovered after several hours of experimenting.

I tightened the bolt after grabbing the clutch ring with a set of vice grips to prevent it from rotating.

There was no damage to the input shaft or anything like that!

So there you have it!

Whatever you want to name it, it’s there.

It goes without saying that it is bent, and there is no way to put the pulley back on.

I should have simply done it, considering all of the resources and time I have put into this project, just to have it turn out to be a complete and utter disaster.

We don’t want to put up an air conditioning bypass because it was working so nicely.

It wasn’t too horrible, in all honesty.

It took approximately half an hour for me to put everything back together and fill it with the right quantity of 134a and enough oil to get it running again. It takes a few minutes to begin going, but once it does, my air conditioning is quite chilly and silent.
