I have a 2003 Chevy Cavalier which I hadn't driven for awhile. When I started it up the other day it started to overheat. It had a new radiator put in last year and it is full of coolant. The fan didn't seem to be kicking on when I let it run.I don't know a lot about fixing cars but I know where the fan is. Although it is hard to see the outer part, which I presume is part of the fan, won't move but the part in front of it will turn. I hope I have explained this so you can understand, it is so close to the radiator that I can't get a good look.Thanks Feye

First, be careful poking around the fan blades. They can start without warning! Don't want you losing a finger! Sounds like the plastic fan blade is spinning freely on the motor shaft. Try selecting "max a/c" on the dash and see if the motor spins. If that's the case, the plastic fan blade needs replacing. HTH. -Jim

Thanks for replying. Maybe I didn't word this right but I meant the first blade type that you can see from the top of the car won't budge but the one behind it, close to the radiator will turn by hand. The one you see first would not move when trying to turn to see if it was stuck. I did try with the AC but nothing happened.
