1987 fj60*
Sorry for the lengthy intro:
The saga continues with my ac. I replaced evaporator, low pressure switch, expansion valve, drier and every o-ring.
I pulled vacuum and it held for 8 hours so I called it good enough and filled with refrigerant. It worked well enough over the next few days.
Fast forward 2 weeks. I pulled it out of the garage to drive it and ac never even gets remotely cold. After a 30 mile drive I come back home and let it cool off and hook up some manifold gauges. The low pressure side was reading super low like 5-10 instead of the 40 ish it had when I filled it.
So my thoughts are leak. Pull vacuum today and I’ve been checking the gauge the last 7 hours on and off and it’s -30. Hasn’t dropped at all.
So I have 3 potential causes and I’d like your guys opinion.
1. I resealed the compressor because there was nothing available online from denso or four seasons.
Solution: buy a used one and hope for the best? still no reman or aftermarket available. Everyone is out of stock and a source at Napa is telling me it’ll be another 4-5 months before they get anything.
2. Condenser stopped up and causing excessive pressure/leaking?
Solution: take it out and get it tested and flushed. Still if there’s an issue with it they are NLA and the prices I’ve seen are astronomical if you can find one.
3. (This is the most unorthodox and me just being crazy) the caps for the adaptors I put on the high and low pressure valves. I noticed when unscrewing the low pressure that some freon escaped. Could a cap cause a tiny leak?
Feel like I’m going crazy and so far have refused to take it to a mechanic. I may end up biting the bullet, but hell a mechanic may not even want to deal with a 40 year old vehicle
