I have a 2003 Sierra and I put a throttle body spacer and a K&N cold air intake filter on my truck. So I had to remove the stock fan and put in a Flex-i-lite aftermarket fan which is alot thinner. I am having so many problems with the aftermarket fan and I am fed up with the company not trying to resolve the problem so Iwas wondering if a 06 or 07 stock fan would fit on an 03 since they the fans are soo much thinner than an 03. I have called a local dealership and the parent co. and no one is sure. Surpise Surprise. Can anyone help me?

 

these guys seem to have a few wrecked chevys and parts up to thier ears.
