Overheat on my 1997 Subaru Legacy GT

I just bought my 1997 subaru legacy gt, it was fine until yesterday after I drove on the highway, the car overheat really bad. So I have the thermostat changed, the radiator cap change but doesn't do anything. It drive good for about 5 miles and right after that the temperature started to go up. The fan is on and I am pretty sure it's not the head gasket. I really want to know what's wrong with it. Thank you.

    its the headgasket. the exhaust from the engine gets through the gasket and "airlocks" the coolent so the antifreeze or {water} dosent circulate.

Sorry if this might break your heart. I have '98 Outback which is the same 1st generation DOHC 2.5 engine. These are common head gasket problem (I'd say 100% of every engine sooner or later) once you have had your car overheated.

You will not get this comfirmed by just have your mech check the compression on the cylinder because we call it phantom leak (internal leak which can be confirmed with hydrocarbon in coolant). And then you will end up replace every other thing before you could reach the source of problem.

Other signs of this issue are as following: random overheating after freeway or uphills drive, bubbles in coolant overflow tank, oil residue in coolant overflow tank, bubble nioses from the a/c vent.

You're looking at $1000-1500 repair by independent mech as they have to pull engine out to fix the problem. I had mine fixed two weeks ago and now my baby is running like a champ.

Possible sticking thermostat (probable) but you could have a fan thermostat going bad also if it has an electric fan, next time it starts over heating look under hood and see if the fan on the radiator is spinning, if not it or the thermostat for it could be bad

I have a 1996 Subaru Legacy LS Wagon. 2.2 Litre. I have been experiencing intermitent engine stumble that only seems to begin after operating at highway speeds for 30-60 minutes. Subaru dealer told me it...

If your vehicle has a MAF (mass airflow sensor), try disconnecting it and running the vehicle. If it runs ok ... suspect the MAF.

Commonly, a fault with the MAF does not cause an engine check light
