Hey everyone. I just purchased a '98 Outback on May 18th, 2007 with 147,000 miles on it for $4200. I love this car but the night that I bought it I took a 45 minute trip away from home and it started overheating while idling at a gas station! I took it back to the used dealership I bought it from and they thought it was the thermostat. They replaced it and but it still had the same problem. I have taken it back 3 times this week! They called the nearest Subaru dealership and they told them to bleed the engine of air which seemed to help. I left with the car and later that night it started overheating again. The needle goes up and down. What should I do? I have now been researching this problem on the internet only to find out that this is a COMMON PROBLEM!! Someone told me I should just purchase a 2.2L engine from a 1995 Outback and have it put in to replace my 2.5L and that I won't have problems after that. I am on the verge of just trying to get the used dealership to take my car back and let me buy something else from them in it's place but I know that is not going to happen without a fight. Please help!!!
