So I'm in the middle of fixing a leak I had in the evaporator on my st185, changed the O-rings according to TSB, Also flushed the system from mineral oil to POE since I'm going to use r134a, thing is one O-ring was crap at the drier and I tried putting in a HBNR from a kit, but it didn't seal, probably because it was just a teeny little larger.
I can only find the O-rings for the evaporator. Toyota doesn't show up the o-rings for the rest of the system, anyone that has done a retrofit, how did you do? since neither the Gti and GT-four have part numbers for the rest of the o-rings.
I'm considering going to the nearest Toyota dealership and check if they have some o-rings in the same size from something else. "Worst case" I'll just have to order an o-ring kit from US which should fit?
Also at the coolant neck there is a broken A/C sensor 8862520300"THERMO SWITCH ASSY" that is removed on later year. Should I permanently ground it or not? It's temperature controlled switch and the a/c only works hard when it's ground. I've tried reading electronic diagram without avail about it, though my Diagram-fu isn't that great. supposedly it has something to do with overheating protection?
Thankful for answers
