I have come once again begging to the experts.....
I have a friends 1997 Chevy Pickup in my driveway - the thing had a belly leak and I replaced the compressor, accum, orifice tubes and the clutch switch (found that out when trying to charge....)
Well, the last guy that worked on this thing buggered up the connection to the accum from the evap side. I got it busted loose - but the threads and such are all rusty. I cleaned it as best as I could.
Flushed, vac'd (held at 25 for 3 hours) and charged. Started losing refrigerant after about 2 minutes of running.
Turns out - the o-ring gave way on the evap to accum connection. ARRGH!
Trying to do this on the cheap - the threads are just rusted up and won't compress the fitting to squeeze the O-ring. Any suggestions? I really don't want to have to pull the evap and get a new fitting crimped and such....
Thanks for all your help over the years.....
If yo can't get it to seal with a new o-ring and Nylog replace the core or have someone weld a new fitting on the end.
Can Tim supply a slightly thicker O-ring?
They make they chasing files,,they are square , come in different sizes and have a a diferent thread pattern on each end and side ,don't know if they have them for that size but might be able to come close or try a small 3 corner file ,,just takes some patience to get the threads cleaned up,,,might be worth a try,,Google it and take a look ,,,,
Thanks for all the suggestions. Nylog didn't make it happen....tried to clean the threads with a wire brush - and the threads disappeared!
Oh well - on to the parts store for a new evaporator!
Thanks for all the suggestions - you guys are the best!
