cap269, I wanted to update you on the situation.
I took out the orifice tube and checked the screens and didn’t find any metal. I also took off the compressor since I had the system evacuated to check my air gap on the clutch as well. The air gap was .0030in so it’s within spec but the compressor still won’t turn. I also looked inside the compressor (as best as I could) to look for any metal shavings inside the compressor and didn’t find any in there either. The whole system is original parts and the car came from Florida originally and is now in NC so it may just be overused and beat up.
I know OE is always the best bet but if you had any recommendations on reliable parts it would be greatly appreciated.
I actually recently replaced the compressor clutch on my 01 Century. Should the exact same R4 compressor. I found the specs for the air gap are .0025in-.0035in. Try the ATF or penetrating oil first to clean it then maybe check your gaps after that.
In order to use the puller/installer tool you do need to remove that nut. Unless you’re taking the whole clutch assembly off that is all you need to remove. It’s going to take some muscle though as these are machine pressed parts and not held on with any fasteners.
This video gives a solid breakdown of how it’s put together.
Thanks for the help cap269 I’ll be sure to check your suggestions out.
Sorry about the picture I thought it had loaded but I can tell you the pressures were 104psi on the low side and 110psi on the high side so there’s definitely no leak in the system. I was just concerned that the low side was too high and the high side was too low.
As far as the compressor clutch goes, what happens when I turn the AC on is that the clutch engages for about 2 seconds and just grinds away on the compressor without spinning it then releases. I get the feeling that this is a safety feature so that the clutch doesn’t stall the car or throw a belt. It will shoot sparks and smoke for those 2 seconds then release for couple of seconds and try again. When it does this there is a very noticeable change in the idle. I’ve only tried it while the car is parked because I don’t want to cause any more damage.
I tried turning the compressor manually with no success.I will be doing a closer inspection of the drain as well as checking under the floor mats for any buildup of coolant. It has been a few weeks since I’ve been able to run the AC so if it was just water it would be gone by now.
I think that should answer all of your questions and thank you again for the suggestions. I’ll be working all day tomorrow so I won’t have time to get under my car but as soon as I can I’ll get back to you with what I find.
