Ea82 overheating

Hey all,

Have posted about this before but havnt sorted it out.

My car has overheated on several occasions. once when coming back from holidays running at highway speed, it was up close (but not on) the red area for a long way, and then when i was going to the airport the other day, in peak hour traffic, it was pretty hot the whole time.

When i got out of the traffic, and got moving on the freeway at ~ 100km/h it didnt cool down at all, but once I pulled off the highway and went onto normal 60km/h roads it started to cool down. I cant figure it out, as it overheats at highway speeds and at low speeds, but not in between.

When i turn the aircon on, the thermo fan turns on, so the fan is working. I run around with the aircon off at all times, and have never heard the fan kick in otherwise. Clutch fan seems to be working fine. Do i need to replace the thermo?

The other thing i'm worried about is that it's a head gasket, but it doesnt overheat in suburban driving, and it doesnt come up to temperature any faster than any other subaru i've ever owned.

Am going to flush the radiator too see if that does anything.

Can anyone give me a hand/suggestions?

Also, because I HAD to run it at these temps to get people to the airport, is it possible that this could damage my engine? (never in the red, but close)

other issues are a lumpy idle, exhaust bursts (not backfire but like a quick rush of air, and doesnt seem to be blowing steam, oil not milky) that goes with the lumpy idle.

Any help would be good, thanks.

Andy

on drivers side of radiator about half way down you will see a sender with t plug pull off plug and bridge out this should make thermo run all the time while ignition on. does your subby have lift kit,are you still runing fan with viscous hub is it manual or automatic?

check engine oil level low oil will cause overheating

make sure your radiator is actually full by filling up at cap not at over flow bottle (sorry some people think they are filling up radiator by filling up over flow bottle)

Get the radiator serviced is the best option - i always over do it in this area to avoid overeating disorders

could have an air pocket in the cooling system. Drain it, bleed it properly and it might sort itself out. (run a decent coolant)

how many k's has the car done? the rad coluld be clogged up. If flushing the system doesnt work, look at getting your radiator 'rodded' or look out for a new one.
