The car runs fine initially and I can drive at 70 mph with no overheating problem, but when I slow down or stop the temp gague shoots up quickly. Once it over heats than the problem stays. radiatior cap, water pump, radiator, thermostat have all been replaced.

SOURCE: 1990 Subaru Liberty Overheats
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,
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.

cool air and overheating point to low coolant level. Do you have a bleeder valve near the thermostat? You may have air trapped in the system. If no air trapped, the radiator may be plugged up not allowing proper circulation of coolant.

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.

test the scanner and computer test for most effective result.
However see if fan/waterpump drive belt is slipping. Coolant is frozen
inlet or outlet water hoses are clogged or kinked. Coolant tube is blocked. Temperature gause is defective. Water pump defective. Fan is too far from radiator,(close it) .Defective water distribution tube. replace the tube. Fan insuficient blade are or pitch replace with large fan or with more blades.
God bless you
