Replacement parts for '04 Buick Rainier

jamyers on Tue October 13, 2015 5:29 PM User is offlineView users profile

Year: 2004
Make: Buick
Model: Rainier
Engine Size: 4.2
Refrigerant Type: R134a

So the compressor is trying to lock up at 150K miles.

It has Auto Climate Control (which I hate) and dual left-right temp controls (which I also hate).

I'm planning on replacing the Compressor, Comdenser, Reciever/Drier, orifice tube at least.

Looking at the a kits site I see several compressors and compressor kits, but no real descriptions to tell them apart except the prices. I want a good NEW compressor, but don't care to spend big bucks. Recommendations?

Also, does the fancy climate control mean a fancy Reciever/drier and/or orifice tube? Looking at rock shows some ad delco parts that seem unique, but hard to tell from their descriptions.

If you have a receiver dryer- you have a TXV (expansion valve) - not an orifice tube- I'd replace with OEM supplier- A/C Delco.

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
