Another shop took in an AC job on a early 90's chevy pickup. They made a mess of things. First they wanted to upgrade the condenser to one for R134a.
They ordered one for a newer truck. FYI R12 ac lines on this truck are sae. When GM went to R134a they also went to metric threads. The other shop tried to ram the lines home.
Had a leak there since the line did not seal. Then they got the correct condenser but managed to cross thread that one. I spent the morning with a thread file,. Torch to clean the aluminum chips out of the metal threads and got it together.
They beat the snot out of the new compressor trying to install it instead of figuring out why it was such a tight fit.
Then fat o-rings where skinny ones go,this cuts the o-ring.. Incorrect sealing washers on the rear of the compressor resulted in yet another leak.
Pics for your enjoyment.
