1990 Subaru Liberty Overheats

Hi,
I have a 1990 Subaru Liberty Wagon that overheats in a strange way. Ok here what I have replaced so far but the problem doesn't go away.
Heads have been rebuilt, new head gasket, new water pump, new thermostat, new radiator, new hoses, new radiator cap. Water system has been bleed and there is no air in the system, water flows nicely through the raditor. Fans come on just under half temp and run the right way.
I can drive the car with no overheating problem and then next time it overheats for no reason. The strange thing is it overheats while just cruzing along and when you rev the motor or put under load going up a hill the temp guage drops under half. You leave the car idle over for an hour and no overheating. I don't understand why underload the temp goes down. I can sometimes drive the car for an hour and nothing happens, take the cap off radiator and water is fine. Then another time it overheats, take the car off radiator and water is boiling over.

Has anyone got an answer as I am about to give up on this!!! Have been reading about air locks in system??? but I have done everything everyone has said to bleed the air out.

Hi,

I had the same problem with my 1993 Liberty LX. Remove the thermostat (located inside bottom radiator hose engine connection - take the connection off and thermostat is inside). Reassemble (minus thermostat), reconnect bottom hose. Slowly (very, very slowly) refill the radiator and remove the bleed plug ( located beside the top hose connection to the radiator - a black square plug with a phillips head cross in the middle). When the radiator is full and clear water (no air bubbles) is coming out of the bleed point, replace the bleed plug and then the radiator cap.

Run the engine for five minutes (approx) or until normal engine temperature is reached. Allow the engine to cool down and recheck the water level - fill if necessary ensuring that the bleed plug is open and clear water is coming out of that point. Replace Bleed plug and then radiator cap. Run engine for five minutes (approx) and then test dive. If the engine overheats keep filling the radiator until there are no air bubbles coming from out of the bleed point.

This fixed my overheating problem. Good luck and safe motoring.

Hi and welcome to fixya,

I had the same problem before. You'll need to have the radiator either checked, flushed or replaced. It could have occumulated deposits which clog the circulation and contributes to heat problems. Also make sure that the water pump is functioning properly. Either of these two causes overheating.

Hope this helps

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.

Engine overheat


Hi and welcome to FixYa,

Offhand it would appear that the radiator fan is not working. In some versions, either the A/C or the heater must be turned on for the radiator fan to work. In some other incidents, the fan utilizes a clutch. Common design makes use of the inverse property of silica oil to serve as the clutch. Still others have a relay that actually does the switching on of the fan. Of course it would be to your advantage to likewise check the temperature sensor on the radiator.

Good luck and Thank you for using FixYa. Happy Holidays.

Both head gaskets have to be replaced and the heads need to be resurfaced, be sure you go thru the torque specs and sequence correctly, it is a strange process, but has to be done. subaru puts out a product called cooling system conditioner, it's advised to install this.
