my condenser is a old style condenser so it can be flushed easily I plan on using the same condenser. It looks like pag oil is my best option here since Im completely flushing the system out so I will be using pag 46 will report back when system is install and filled with refrigerant.

I got a new compressor, expansion valve, and drier the car was retrofitted in 2000 from r-12 with mineral oil to r-134a with ester oil. I'm doing a full system flush and replacing everything except for the condenser and evaporator my question is should I use ester oil since that's what they used whe...

So I installed the new pipe pulled a vacuum for 2 hours then started to fill the system with refrigerant and I saw the compressor engage for about 5 seconds then turned off so I took the relay out and bypassed it with a wire so the compressor was running right when I started the car so I started fil...

UPDATE: I uninstalled the compressor once again from the car an tested the resistance and I got it to read 4 ohms the reason I couldn't get it to read that before is because I was touching the multimeter probes in the wrong location, Its a older style compressor it has more wires than a newer compre...

yikes so I just looked at the bottom of the compressor and realized that there is still a leak in the ac system coming from the high side line that connects to the compressor (no this is not the original leak this is a different one) I was confused why it was leaking from this line because I replace...

Here's a picture of the retrofit tag https://imgur.com/e5BGFDS It says they used 4.24 lbs of refrigerant idk if they meant to write it in the oz's line because that would make more sense because 4 pounds sounds like way to much. And for the oil type I'm pretty sure they wrote ESTERCOOL which is este...

There's a picture of the compressor info I couldn't find any info online about it.
Also the compressor was running while there was a leak and it was making the air cooler but since it had a leak I don't think it was working very affective.

Its a Bmw 750il 1992 e32 series I also drained and refilled the compressor recently when i fixed the ac leak with 5.7oz of ester oil because the car was converted from r-12 to 134-a in 2000 and its says they used ester oil on the retrofit tag.

Just recently put new oil into my compressor since there was a leak in my ac system, I fixed the leak and also replaced the drier but when I fill the system up with refrigerant and the car is running with the fans on max with the ac on I cannot get the compressor to engage. I filled the lowside with...

Just some back story for the car. The ac was retrofitted from R12 to R-134a in 2000, the car had sat for about 15 years or so not being ran but within the last year ive got it running again i realized there was a no cold air in the ac system found out later that there was a leak on the compressor co...
