What A/C Compressor should I purchase?

What A/C Compressor should I purchase?

Postby nolatrader33 [OP] » February 11th 2020, 6:42am

Hello,

I'd love to get someone's advice on what A/C compressor I should purchase. Figured I would ask the experts since I've had bad luck in the past purchasing the wrong type of part(s) which ended in frustration after tearing everything down to find out I had the wrong part :roll:

I have a 2002 Chevy ASTRO RWD with REAR A/C

I attached a photo from Rock Autos website that shows the different compressors available for my vehicle. I noticed some of the brands have different options or features.

Also, I've been told when your A/C compressor goes out that I may need to replace other A/C components due to the possibility of metal shavings that may be in the line. If this is true, what other A/C components will I need to replace?

Thanks!

They make bolt on filters for the metal shavings now. Much cheaper than replacing all that crap and also more reliable. Because the replacing parts does not guarantee shavings are not in other parts of the system.

Compressor you need is dependent on which it has they have different manifolds. It is a pain I know and I am not familiar with the newer vans.

Best resource for this is a good seller on e bay. they have what fits what. Then you have to get the serial number on the compressor.

I just went through what you are with my Tahoe there were 3 different compressors for it. I ended up personal messaging the seller he knew which one it was.

Year engine size(yea I know they all the same)and rear air or not are the 3 things you got to enter in the boxes.

Engine size is a criteria. Older vans had several type engines. tbi etc. it is just what they want to know to make their search work.

Thanks for the info. I'll look on ebay and see what they come up with. Regarding the metal shavings, would my year van (2002) have the bolt-on filter or is this an aftermarket add on?

It is a aftermarket add on. It goes on before the lines.

It is a pain to find them but they got them for everything. I got one for my Tahoe that was eating compressors. Never did it again.

This image is from a autozone ad. I got mine off of E Bay.

Stick it out find the one for yours it is worth it.

For that I like to search the GM parts sites, can search by year/model/etc or by VIN. You will probably find that you have an HT6 compressor(96-05), then use that part number for a cross reference to which one you want to buy.

Depends on why you are replacing the compressor, if it's the most common problem, a leaking seal, then you may not. You will have to pull/replace the orifice anyway, so you will get a glimpse of what is going on there.
Don't forget a new receiver/dryer as well.

Trolls take away from productive work, best to starve the troll of attention by ignoring it and going about your business.
