I had the same problem, taking the thermostat out helped for a bit, but keep an eye on it it could be a sign that the waterpump is going out. shortly after i took the thermostat out my waterpump failed.

Well....if that stopped your overheating problem, that's good, but todays engines depend on running at a certain temp. for proper performance, gas mileage, etc. We can thank unleaded fuel for that....

95 Subaru Legacy overheating, top rad hose is hot, bottom hose is cold,antifreeze being pushed back into overflow bottle, fans are working properly, what is the problem ??


does your heater work? if not than your thermostat is stuck. be careful not to get the car hot as those engines are sensitive and will warp the cylinder heads quickly.

1990 Subaru Legacy with an intermitent overheating issue. Has had the thermostat replaced. Any ideas? Thanks, Graham


I would fill radiator with fluid, start car and allow to warm up. Watch catch can for bubbles. If there are bubbles I would suspect a head gasket leak.

Where is the thermostat located on 92 legacy


The thermostat is located under the engine Follow the lower hose from where it attaches to the engine. Be careful with the bolts, use penetrating oil, you do not want to break one. Try to use a Subaru thermostat and gasket-- expensive, but cheaper than an overheated engine, most places do not stock the required thermostat, being an oddball temperatiue (167F), putting in a "regular 195F" thermostat WILL cook your engine. The gasket is really an O-ring affair-- it works nicely. Try not to re-use the old O ring gasket.

90 subaru legacy overheats, wheres the thrmostat


When a car overheats it's rarely the thermostat. They just don't go bad that often. If it overheats when you idle a lot, it's the fan and with electric fans, it's almost always the fan motor. But to find the thermostat, follow the top radiator hose to the engine and there it is.

Overheating


Have you checked to see if the radiator fan works? And have you checked to see if the water pump works? Two very important items key to overheating.

1997 subaru outback legacy overheating


I hate to tell you this but the guy isn't returning your calls because the head gasket is blown and he probably knew it.
As for the 1990... have you checked the water pump for leaks? (front/ driver's side on the bottom of the engine) My guess is that it's faulty and unfortunately, it's behind the timing belt.
Both of these repairs will be a pretty penny.
Good luck!

Overheating


Multiple causes for overheating. Start with thermostat.

I had an overheating problem in my Subaru that ended up being a head gasket (I replaced thermostat and radiator, but these did not help). It turned out that the head gasekt leak was allowing air into water passages that prevented water circulation in the engine.
