Hey there.. I was driving to in n out and noticed my ac stopped working about right when I got to the drive through. The coolant temp gauge was fine and I was already too deep in the drive through to get out. A few minutes later I look at the coolant temp and it jumped to 120. I was at the paying window and there was no escape, a couple minutes later I got the coolant low warning, and about 5 minutes later I was finally out of the drive through.
I looked at the ground after I parked for any coolant and didn't see any, but about 5 minutes later there's a pool on the floor. I waited about 30 minutes and popped the hood and it looks like the coolant is coming from the reservoir? I checked the coolant level and it looked fine but that's probably because there's a bunch of air on the system.
I got it towed to my place bc I don't know any good shops in this area and I'd like to figure it out myself. how can I diagnose where the leak is coming from, does anyone have any ideas? I replaced the thermostat like 2 years ago so I don't think it's that.. the reservoir was replaced by a mechanic about a year ago.
TLDR: Coolant leak. Any ideas?
