Changing your compressor oil

Changing out your York Compressor Oil

Part #:

When you receive your compressor it will have refrigerant oil in it.  This can be bad for air systems, especially ones like the AiROCK.  I changed out the oil and added normal 10W-30 Motor oil.  Non-synthetic.

Additional Parts:
10W-30 Motor Oil (12-16oz)
Small diameter Hose
Tools Needed:
Combo Wrench
Turkey Baster
Measuring Cup


1. Assemble your parts.  I used a plastic measuring cup (since I didn't want to hear it about putting oil in one used for cooking).  I also cut the end off of a turkey baster and inserted a small diameter hose into the end of it.  This will be used to suck out the oil from the compressor.  Now if you have not installed the compressor yet, you can just remove the two fittings and drain the oil out of it that way.

2. Remove the oil return hose.

3. Remove the oil return fitting from the side of the compressor.

4. Use the turkey baster to remove the oil from the compressor.  This takes some time.  I measured it out into the measuring cup so that I could see how much oil was in the compressor.  Normally this will be between 12-16oz.

5. Clean out the measuring cup and turkey baster.  Fill the measuring cup with the same amount of oil that you removed (12-16oz) and used the turkey baster as your funnel to refill the compressor.

Common Sense and Safety should always be observed when working on your vehicle or doing modifications. Jackstands, wheel blocks, disconnecting the battery are a few of the basic safety precautions that should be used and may not be mentioned in the write ups on this site. You are responsible for your own installation, these write ups are a helpful guideline and should not be taken as an official installation instruction. My write up may be different from the kits currently out there, so alwasy double check the manufacturers installation instructions when installing anything. I try to keep the site up to date with changes that have occured as I discover them, but may not have the latest unless someone lets me know. If you feel that an install is above your capabilities after reading my write ups, I recommend getting together with a club and getting some help. Only a few times have I needed to employe some actual help from a shop to get something done. Usually welding or A/C work.
