Why does my car squeel/whisles after warming up
2003 Volvo S80 2.9 Liter
Car squeels real load after warming up. It never runs hot according to the temp gauge but engine feels overheated. Uses a lot of water but doesn't smoke. If I leave it started, sounds like I'm pressing on gas. It seems to drive okay but check engine light is on. It doesn't seem like the fan kicks on and off correctly. I fill with water now instead of antifreeze at least 3 times in 2 days. Recently it just stopped needing filled completely. I'm afraid of cracking the head or worse. What could the problem be?
