Tom, can I install a flex-a-lite myself? Or do I need somebody who knows what they are doing to do it?

Thanks amigo!

The install isn't bad at all. The main problem for a first time install is trying to figure out which wires to tie into for the AC and for keyed power. I'll see if I can dig up the info that I posted last year.

Here ya go -

I installed a set of Flex-a-lite 290 fans into my 2002 Silverado HD with the 8.1 motor. This kit comes with universal brackets so you pretty much have to come up with a way to mount the radiator. The info below should carry over the the 8.1 Avalanche. I'll be putting a set into my Suburban next week and will let you know if there are any differences between the two trucks.

I bent two of the brackets so they could be mounted to the top of the radiator support and then hang the fans from there.

After that I used some plastic strips from B+M to attach the fans to the radiator. I don't remember the part # for these but I can get that tomorrow.

Trucks with the Allison transmission have a seperate computer to control the tranny. This is mounted on the driver's side of the fan shroud. This will press up tight against the fans. I tried a few different locations but it was starting to become in PITA so I figured the stock location would be the best choice. I tried out part of the cover so it would go around the bracket and then mounted it leaving the two 10mm bolts a little loose. I also tied the bottom of the plastic cover back away from the fans with some straps. I might come up with a better way to do this but it's working pretty good.

While I had everything apart I also installed a ported throttlebody and throttlebody spacer. Did some driving that might and found that I gained close to 2 MPG. This truck gets thirsty with some of the mods and big tires so these were worthwild additions.

If anyone else is thinking about using these here are a few quick notes that will help your install. The fan controller needs to be connected to a wire that is hot when the truck is keyed on and cold when it is off. If you take the cover off of the fuse box under the hood and then lift up the cover that has the fuses in it you see 6 different sections. I used a wire in section 1 ( top left hand corner). Count two wires over from the right and 3 down. You will find 2 wires here. I used the purple one on the right. You also need to tap into the activation wire that goes to the clutch compressor for the AC. There are two wires there. I used the green one. These tips should help you get through the install in a couple of hours.
