What temp does it run at? Vehicles are usually set to run around the 190' mark. So if it gets a bit hot when your using the a/c that's not uncommon. If the needle doesn't go into the red, don't worry about it. Why waste money on something you don't really need.

A lot of guys have switched to the shrouded plastic fan off of the Aerostar... more efficient and lighter.... I may switch to it, but may also see if the one off of my '02 Bravada will work (it's got a lightweight aluminum clutch!).

Here's a link to the Aerostar fan....

The fan on my '99 montana van looks very much like it would fit. It's a dual-fan set up that could be staged to run the second fan only at high temps.

I like my stock fan, but the darn thing is really close to the shroud now with the new motor mounts. It might have to go...

Anybody know- is the astro fan the same diameter as stock? If it were even 1/2" smaller it would help me a ton....

Aerostar???? I think you want Chevy Astro or GMC Safari. This fan was used on all of the following with the GM Part # of 15976889 . The number below is the AC-DELCO part #.
