Since it is a GM product. GM Parts Guy on this forum should be able to get you a price.

Any Hummer Dealership should be able to install the fans.

However as I am finding out and as it was admitted to me by the service manager and a GM master mech, the H2 even in it's stock form has a very inefficient cooling system. Put a Super Charger on along with it's inner cooler which blocks 1/3rd of the front grill and you have a cooling issue.

Last summer here in town there were non supercharged H2's being towed into the dealership with cooling issues. This I personally witnessed. I've been on the phone with Corporate and customer service for Hummer for countless hours and they seam to think it is an isolated problem here in Nevada during the summer months. This doesn't explain why 2 1/2 weeks ago when it was in the mid 80's on my way back here from Ca and the truck over heated on one of the two 4000 foot climbs over a mt. pass. Nor does it explain why I got a "Hot Transmission" warning indication from the dash display while traveling to Big Bear Lake with an ambient air temp was in the low 60's, Big Bear is at 8,400 feet but I wasn't towing anything or racing up the mountain.

While my dealership is taking forever to do anything with my truck, mostly because they don't know what the trouble is they are covering it under warranty.

I am going to look into a different radiator, oil cooler, trans cooler and possibly a high-out water pump. I need to find a way to dissipate more heat. I agree the t-stat change probably isn't going to solve anything. I also don't believe that any one thing is causing my trouble.
