Old Compressor Flushed clean. Do I flush whole system?

Bench on Fri July 16, 2010 3:05 PM User is offlineView users profile

Year: 2001
Make: toyota
Model: tundra
Engine Size: 4.7
Refrigerant Type: 134
Country of Origin: United States

I took the old compressor off and flushed it with pag 46 several times and nothing but oil came out on my paper towel. Do I need to flush the system, or can i just put the new compressor on, change the dryer, and then vacuum and fill.

That would really depend on why the compressor was removed?

I think Bench is stating that his old compressor failed, but that he sees no metal debris in his flushes of it, so he wants to know if he must flush out the Tundra's lines, etc., as well, before he installs his new compressor.

The old compressor was starting to not work, said my mechanic. The air would work, then not work. So I bought the advanced ACkit, and doing the work myself. It wasn't black death. The oil that came out of the old compressor looked really clear.

Judgment call! Flushing will provide a starting point for proper oil amount. But if you leave flushing agent behind you will break down any oil in the system.

Did the mechanic say that your AC clutch was going (intermittent engagement), so it would make sense to just swap out the entire AC clutch/compressor? If so, I would not flush the system.

I swapped out the compressor, and didn't flush the system. It is working great. Blowing cold, cold air.

Thanks for the help!
