1990 Subi Legacy EJ22 SOHC overheating

Showing 2 out of 2 Posts
Question From subisnacks on 1990 Subi Legacy EJ22 SOHC overheating

Hi, I have a 1990 Subaru Legacy wagon with EJ22 SOHC engine. It has been overheating, mechanic told me it was the water pump. So I had a car project weekend & here's what all I fixed: new water pump, new thermostat, new timing belt & idler pulleys, new valve cover gaskets, new oil filter & oil change, new coolant, new radiator hoses & clamps, new alternator belt. After all that work its still overheating, it starts up & temp starts to go up, but it doesn't stop at operating temp it just continues to go up & up & in about 15 minutes the temp is thru the roof (either at idle or while driving, driving seems to get it there faster). So I'm thinking clogged radiator? Any other ideas?

Response From nickwarner Top Rated Answer

You could have a plugged radiator, could've put the thermostat in backwards, could have blown a head gasket or may be as simple as you haven't gotten the air bed out of the system yet. Double check your work.
