anyone have this problem? when the car gets to a certain temperature the fan automaticallly turns on. Mine makes a loud rattling noise which is pretty embarassing. is this common and how did u solve this problem? the rattling noise comes from the fan turning.

 

Replace the fan.

 

I JUST had that same problem fixed. It's because the ball bearings are shot. Only way is to buy a new radiator fan. I got mine off eBay for ~$115 shipped and replaced it myself - pretty straightforward job that takes about 20-25 minutes.

P.S. - It really is a pretty embarassing sound...lol.

 

will a 2003 radiator fan fit in the 4th gen. i got one line up but it's a 5th gen.

 

No idea...someone else will have to help you out there.
