That's my main dilemma - if it was driven too long while overheating. It's the time and money I have to spend to check it out that I'm not into, but here on vancouver Island there aren't many nice old Subarus left. Lots of 90's wagons, but not much for pre '85's (I have something to do with that - 4 of mine were scrapped in the end).
Now another thing. . .
Is there a way to prolong the overheating factor? I will squeeze the air out of the rad, crank the heater, and was thinking of removing the thermostat. . . well I guess I could just put in a new one. I need to drive it 20kms to the ferry, and then am trailering it home from there, as it is REALLY expensive for a truck/trailer on the boat!
How can I check if the waterpump is working, and will a quick compression test tell me if one of the HGs is blown?
