Cooling Problem with '97 Subaru 2.5

I have a '97 Subaru 2.5. I have a over heating problem. No leaking of fluids. The water in the coolent doesn't seem to be circulating. Could the thermostat in the closed position be causing this? Could the radiator cause this? Thank you.

1. If the fluid fails to circulate even when the car has been run to full temp then the thermostat has failed.
2. The radiator will not cause this unless it is obviously clogged. You will be able to see evidence through the cap hole if this is the case.

Thermostats are cheap and relatively easy to change.

1. Inspect radiator for obvious clogging
2. make sure levels are where they should be in the system
3. replace radiator and retest with proper coolant mix

    CORRECTION - I meant replace Thermostat and retest. Sorry about that scary confusion.

Sounds like one of 2 things, the thermostat or the engine has a leaking head gasket, replace the T-stat 1st, if the problem persists have the engine tested for blown head gasket(s) if the radiator was the problem u would have circulation and engine would overheat very slowly or just hotter than normal.

I have a chevy equinox that was over heating and would leak coolent took it to the garage they said it was a water pump and the thermostats they changed them and flushed the tank. Not a week latee it over...


I suspect there was an air pocket in the cooling system, sounds like the garage didn't bleed the system completely, just keep an eye on the coolant level, if it remains constant I would suggest your problem has been resolved. But don't forget, only remove coolant cap when engine is cold. Regards Mike

Coolent leak in m0tor. Not sure if it is the water pump or not. Is this a common issue for 97 siloette? How do I fix the problem?


It could be the water pump but the intake manifold gaskets are another common place for these vehicles to leak coolant. You'll have to fill and pressurize the cooling system to pinpoint the leak before determining how to fix it.

Put a pressure test on the cooling system and the leak should show.Also check the engine oil level,is it clean oil,coolant free,does the dip stick show any traces of coolant?

90 legacy, started overheating but was blowing cool air out of the heater even as the needle was pegged. Some fluid in reservoir, top radiator hose felt like it was under a lot of pressure.


Two things would cause this

There is a slow leak and the radiator is low on fluid

Let the vehicle cool down completely and then check the level in the radiator. I bet its pretty low. Top off the radiator with a 50/50 mix of coolant and water. start the vehicle and let it warm up with out the radiator cap on. Keep adding fluid as necessary. While waiting for it to warm up check around for any abvious coolant leaks. Things like hoses, radiator seams, water pump, water inlet/outlet gaskets. If no leaks are found it may be necessary to pressure test the cooling system and even then it might be a slow leak that only occurs when the vehicle is cold.

If the radiator is full than I would suspect that water pump is no longer working or creating enough flow. If the thermostat where stuck you would still get heat. If the water pump is not circulating coolant than you would get no heat and the car would overheat.

Sounds like a small leak at head gasket or Water pump going. Small leak on head gasket under idle will leak slow, But when under load will leak faster. Have a compresion check done on the cylinder to locate. Also you might want to try a presure test on the coolant system. Good luck and hope this helps to get you going again.

Overheating after changing the head gasket


Yes ! Why were headgaskets done in first place, obviously over heating problems. Were the heads checked for cracks, or replaced? The entire cooling system should have been checked to begin with, and hopefully when re-assembled, it was done properly, as well as bleeding procedure performed correctly on the cooling system. How about filling us in from the start?
