compressor going bad?

hotstang on Sat April 18, 2009 6:07 PM User is offline

Year: 1993
Make: Ford
Model: F-150
Engine Size: 5.0
Refrigerant Type: R-12
Country of Origin: United States

My 93 F-150 with a 5.0 is starting to make a rattling noise in the compressor. It is the original compressor running R-12 and the system has never been opened in 225,000 miles. I checked the pressures and the high side is 80-100 depending on temp. When I change the compressor I would like to change to R-134. What do I need to replace beside the compressor or do I need to open the system to see what all has been contaminated before ordering parts? Which compressor would you suggest I buy to replace this?

Pull the O tube and check it for debris, then flush the system of the mineral oil, change the O tube and accumulator. Use PAG 46 oil or BVA auto 100 ester oil. Ackits.com shows only the Sanden SD 709 compressors, but send an e-mail to the guys at ackits.com as Tim put up a post for new FS10's made by sanden which should work great for you. The condition of the O tube will tell us more of what needs to be doen, or maybe just the parts swap and flush.. Let us know what you find.. Hope this helps.

Here is a link to new FS 10's if you have factory air. Dealer air requires the SD sanden.. I would also consider using R12 since it served you well for 225,000 miles.. Just a thought, it's still available...
