After changing coolant in my car - it still SOMETIMES overheats. The needle goes a little towards 3/4 mark, not very often - when i sit in traffic. I've spent hours searching and reading archives...I have a new water pump , new T-stat. I bled the system today.... What did i found???? I found that i can stop my fan blade with my hand!!!!! Which i've read isn't normal and i think it's about time i change my fan clutch... Maybe this will help me with my overheating. But one thing still bugs me - when I turn the key the temp needle is at 3/4 mark - many of you replied to me that this is normal and my needle goes back to middle mark in less then 30 seconds. But it didn't go up first week And my friend who has 94 530 doesn't have this problem either.... Anyone can suggest me something on this hot start "problem"? One more question: Where is the cheap place to buy Fan clutch and Oxygen sensor (it wasn't changed before and my MPG is 11 in city). Thank God there is such thing as this board and archives... To Bruno: Nice website!!!!Very helpfull....!!!!! Thanks for input!!!
