more info....
I checked the coolant recovery and did not notice any black scum. build up.
Yesterday I started it up and it ran idle for about 30 minutes, I drove it about a mile up the street and it overheated again.
I will try the radiator cap, and check for bubbles and let you know.
grossgary, thanks for the offer, I will keep you posted.
Thanks grossgary and WAWalker.
I will check the coolant recovery tonight.
My Forester is 98, and it has about 160K on it.
I am honestly not sure if the car overheats because it looses the coolant or if it over heats for some other reason and the coolant gets too hot and then blows.
I have a 98 Subaru Forester that I need some feedback on. About 8 months ago I noticed the smell of antifreeze in the general area I was parked in. I did not pay it any mind and drove home, about 10 minutes away my gauge shot up to H. I quickly pulled over and let the car cool down. I had to do this every few miles or so until I made it home. Once the car had cooled down I topped of the antifreeze, which did seem low. I did not have any other problems until maybe 4 months ago, same scenario. The car can sit in idle all day and it will not overheat but intermittently a 5 minute drive sends the gauge to H. Any ideas? So far I have heard thermostat, fan relay and head gasket.
Thanks.
