WHY IS CAR OVERHEATING?

1990 Subaru Legacy • 104,000 miles

The water pump was replaced 6-8 months ago. Problem reoccured. Replaced radiator, hoses and thermostat. Drove about 30 miles city and hiway-no problem. Next day drove another 30 miles and overheated again.

You should also make sure the fan is turning on it is important. When the temp is about half you should check if its on

Make sure cooling fan is coming on. Check for issues with timing and head gaskets.

The fans do come on normally. I didn't consider a timing issue since the engine runs very well. I don't see any evidence of coolant in the oil or external leakage.

Check to see if any of the radiator hoses are collapsing.
