Title: A/C Questions...
Post by: kenf729 on May 31, 2009, 05:43:37 pm

Well my 77 K10 had A/C, but PO pulled out the compressor and condenser.  some 4 wheelin buddies gave me a good(?) compressor and condenser...my question is this since it's been apart for years...what should I replace besides o rings...I know I will need to vaccume it down to test for leaks...but everything has been apart open to the elements for probley 20 years...

I've got a new stile dryer with the switch built in...v.s. having the switch in line, which would be better?  the newer dryer I pulled and have it in a plastic bag keeping stuff out...

Replace the acuumulator, orifice tube and flush everything out. Retrofit and Vacuum the system. Refill it with Ester oil and R134a.
