Air Conditioning Compressor Clutch availability
 

It looks like my AC clutch is toast. I've searched here and online extensively without finding a definitive answer. I suspect the one listing for a ac clutch compressor to suit a ZR-1 is erroneous because it lists it as being compatible with both base cars and ZR-1's.

Can anyone confirm if the clutch is available separately or do I have to buy a whole compressor to get a new clutch assembly?

Link to the ad which I suspect is erroneous: https://www.topflightautomotive.com/...ressor-clutch/

There is some info in regards to the clutch I believe on this site somewhere. This is an issue that's been addressed before so the info is out there. At one point I had planned on getting a spare for my stash. Google A/C clutch ZR-1 and it should pop up.

Been barking up this tree for a bit. If I may add to the confusion, from the same site there is a listing in the link below for a clutch that ?fits? 1990 ZR-1s only. To my knowledge, there was no difference in the pulley diameter, connector or clutch design that is different year to year for ZR-1s. Unfortunately, these sites have a lot of help that is not familiar with specialty vehicles within the Corvette brand.

AC clutch for base L98 is #10158036. LT5 # is '90 # 10158044 &'91 is #10157970.
Compressor for base L98 '90-'91 is #10135601. LT5 '90-'91 is #10090565.

As per part #'s base & LT5 are not interchangeable?

I started looking for the clutch and assorted parts a few years ago and got side tracked,I'm on the hunt for a clutch coil if anybody happens to see one. Part number for the coil is 10157969 I believe.

I just checked ROCK AUTO and they have the clutch assembly.

You guys are brilliant.

Thank you, finding out the part numbers was next on my to-do list. I appreciate you sharing the information. I'll also email that vendor to let them know their listing is incorrect.

Thanks Jeff, just placed an order for the clutch with them. :cheers:

I believe the 1990 Clutch has a different electrical connector than the 91-95, but I could be wrong. I know it changed on the L98 cars my 89 connector and the 1991 connectors for the L98 cars were different

I bought the last GM clutch coil they had.

Re: Air Conditioning Compressor Clutch availability
 

I see those on RockAuto, but are they for DOHC? I would not think Chevy would allow something like a different AC pulley diameter for an LT5. I have an old screenshot of that same clutch and the old site I got this from stated it fits DOHC compressors as well.

Re: Air Conditioning Compressor Clutch availability
 

It states the application is for a DOHC 5.7. I bought both the OEM coil and the aftermarket clutch assembly.

On top of this, Top Flight Automotive has not been any where near Top Flight for me. I had parts on order with them for over 6 months and cancelled my order.

Re: Air Conditioning Compressor Clutch availability
 

I bought the complete aftermarket clutch assembly they had just so I can drive the car. I'll pick up a spare compressor for the parts shelf soon.

Re: Air Conditioning Compressor Clutch availability
 

I just got the GM coil and it's not the same as the coil in the aftermarket clutch. Is it possible that the aftermarket clutch assembly isn't exact as the OEM clutch? Both the aftermarket clutch assembly and the OEM clutch coil I got from ROCKAUTO with part numbers that correspond with LT5 DOHC.

Re: Air Conditioning Compressor Clutch availability
 

I also found a new GM part number that supersedes the OEM clutch assembly part number,I didn't note the number put the part shows several places has it in stock at $260 for the OEM clutch assembly.

Re: Air Conditioning Compressor Clutch availability
 

What is the new Part number?

Re: Air Conditioning Compressor Clutch availability
 

One of the part numbers is 10243785 which is the OEM clutch package.
