Hey guys, I need some feedback- the shop where I took my car is stumped.
Short version:
My 97 subaru 2.2 will overheat randomly when I come to a stop, but will return to normal once I get up to speed. The heater does not work at this time but will work otherwise. Everything else works.
Long version:
About a month ago I got a bubble in my radiator (overflow tank got too low). I refilled and burped. Worked fine but notice I had small leak in radiator. Got the radiator fixed.
Now the car will overheat but seems to happen only when I get off of the highway on my way to work in the morning (after about 20 min of driving). I brought the car to the shop. The car does not overheat in the hands of the guys at the shop, although I brought it in hot yesterday. They have checked:
Compression
Thermostat
fluid levels
Fans turning on
Heater core (based on something I found on another forum).
Water pump
Everything is fine. They do find if they let it run with the radiator cap open that occasionally bubbles will show up. Sometimes fairly big, sometimes tiny.
Current guess is hairline crack in head or head gasket but the issue there is that the bubbles are not consistent (I guess they are supposed to be consistent with head/head gasket issues) and the car passes all other tests.
I've had the car at the shop three times to try to figure this out and everyone is really stumped.
