Thanks. When I had the Head Gasket changed, year and half ago, I had the T-Belt changed also.

This is a continue from Mysterious cooling problems. 03 Outback w/ 4 banger. What would be some symptoms indicating your water pump is going out? As I'm driving down the Interstate, 70+ mpg, the temp starts to rise to 3/4 and higher. I have the Transmission, (automatic) in Drive and with RPM around 3000, I drop the shifter in 3rd which puts the RPM to 4000 - 4500 and the Temp needle drops to the center, shift it back to drive and it slowly creeps back up. But not always in the same amount of time and the Temp will drop at any time also. The only thing I can think of is the pressure increased because of the RPM increase, which would put out more pump pressure, if I'm thinking correctly. And possibly because of the increase of pressure, the T-Stat opened up. I bought an OEM T-Stat and will be putting it in tomorrow. The Head Gasket has been changed and I'm not ruling that out as the problem either, Hopefully ShawnW, will help to check if it is the HG, if the T-Stat does not fix the problem. Bought a OEM T-Stat and gasket. Installed it and been driving it for three days with the temp running normal, right dead in the middle like it should be. Spent $22, compared to what a certain national service center chain charged me for not fixing it. I blame myself for not checking further into this or joining this forum sooner. Thanks everybody for all your replies.

I don't believe it was an OEM T-stat that was installed. Your right it could be a bad part from stock.

Demin water Never heard of it.

The fins are clean and the T-stat has been changed, when they changed the Head Gasket, which they said was bad because of their test that was done, wheather or not it was the Hydro-Carbon or the Leak down, I couldn't tell you. It was one of those situations that my wife took to them because she was getting her oil changed and had them take a look at it and I have been suspecting the Head Gasket given Subaru's history. So I told them to change it along with the T-stat, Timing belt and I know there was something else but can't remember. I'll never have the Subie serviced there again.

ShawnW, I'll send you a PM. It'll make t up there, as I'm driving down I25 the temp will fluctuate up and down. I won't be able to get it up there till this week.

Hey newbie here. Have a 03 Legacy Outback with the 4 banger that runs hot, according to the gauge, but does not smell hot, lose any fluid or have any symptoms of overheating. When the temp gauge does start to rise while driving, I have pulled over several times to check fluid level and to make sure the fans are running and all is good. When it started approx. two years ago I took it to a shop and they changed the Head gasket and fluid. After taking it back several times and having them tell me they found something andthey would fix it but as I drove it away the temp would just rise up again. If somebody could give me any suggestions other than to get lost, would be helpful.
