Did I miss something? Everything I have read, on- and off-forum, says PAG 150 for an OEM compressor. Yet, they sent PAG 46 and the compressor says RL488 or equivalent, which is PAG 125 from what I could find on google. I'm pretty sure I need to use PAG 150 for this, but I would just like to double-check before proceeding.

This is the link to my write-up from when I installed my AC system. It might help. Apparently I had to use the PAG 46 oil for mine which was a one-for-one replacement for my original system.

https://blazerforum.com/forum/2nd-ge...ent-kit-97066/

I remember coming across this thread! I am actually planning on following some of the guidelines mentioned here in conjunction with other resources.

I am somewhat familiar with GPD, in that it is not OEM and uses PAG 46 by design. But since my part is OEM, I would think it should follow the fluid types/amount tables.

Here are the specs for my 99. Unfortunately they don't say what type of PAG oil to use. Perhaps a dealership parts counter could help you figure out which to use?

Found plenty of resources telling me that an '01 S10 OEM compressor takes PAG 150 (8oz for the entire system); just thrown off by BAP sending PAG 46, the compressor label mentioning RL488 (PAG ~125), and how those contradict each other and manufacturer manuals. I'm pretty sure BAP screwed the pooch here, but their customer service is TRASH. But I guess the next step will be to call a dealership.

Ask the vendor, they may even exchange at no cost.

The oil type is dictated by the specific compressor make and model and is related to its design/clearances. That is why you can get two different after market compressor brands for the same vehicle that specifies two different oil viscocities. It’s a Denso vs Sanden ... thing, not a truck make and model or engine model thing.

Here’s another oil viscocities chart. If you are wanting to confirm the proper oil viscocity your best bet is to communicate with Delphi for direction but you may well be right about pag 150. When I did my compressor about 100,000 miles ago I think I confirmed by matching up the compressor body with some reference outlines of different compressor models.

George,

These lIsts should be a sticky!

Where did you find the first list?

Yeah, I just figured that since I purchased an OEM part, it wasn't important to make a distinction, but definitely noted for the future!

After a quick search, it seems like my Delphi is a GM HT6, so PAG 150 it is.

Any comments on all the links I just found during my search which brand the HT6 compressors as "known belly-leakers"? I was trying to keep everything OEM in an attempt to keep the replacement process as simple as possible, but now I am wondering if that O-ring is going to crap out early or if there is something that needs close attention to detail during the installation process to avoid this. (My bad if this should be a new thread.)

Here you go Christine. This site also has a partial compressor identification section:

Some compressors come with a charge of oil already in the compressor, some come dry. Regardless, the process is to pour out the oil in any part that is removed and replace that amount of oil in the new part. If its a compressor and its pre-loaded with oil then you pour it out, and replace the proper amount. Alternatively there is a chart with the amount of oil that normally resides in each component (the oil is always distributed throughout the system).
