I'm looking at putting a electric fan on. I know about the Taurus and Lincoln fans. What are the guys using, Aftermarket, OEM, ???? Wondering about the experience with them daily? Thanks

What are the ls1??
All it is....Is G.M.'s 3 digit Code for Identifying the Engine's.....Engine Codes ......LS1....LS5.....LS6....LS7.....LT1....LT-1....L98 and so on.....they are G.M's way of Identification.

So....a LS1 is a....
5.7L GEN III V8 ENGINE.....the Engine Code's are RPO Code's which stands for Regular Production Option....and these RPO Codes are what your Truck came with from the Factory.....from what size engine to the color of your Interior,

If you enter your trucks Vin # Number in the below link and it will show you what your Truck came with from the Factory,

In short....The E-fans are from the LS1.....

Guess I should have been more specific. What models are they in that will work? Year? Etc. I haven't kept upon the newer RPO's since I got out of selling parts about 13 years ago.. Thanks in advance!!!!!!!!!!!!!!! Was a Chevy partsman for 2 years then went to an aftermarket parts chain.

LS1 F-Body's were 1998-2002.
LS1 Corvettes were 1997-2002?
LS1 GTO's 2004.

I know the F-Body ones work for sure. Unsure on the others.
