hey guys, back again with another prob from my clunker..lol..anyway, here is what happened to me tonight. drove about a mile from the house to fill up on gas, then drove another mile to pick up some fast food, i probably waited in line 3-5 mins i would say, and when i left i noticed the hot-cold gauge was 2/3 of the way up, it usually stays 1/3 of the way up, so i knew something wasn't right. checked the coolant reservoir and it had plenty, and the oil level was ok! what could be making the car run hot like this all of the sudden?
