Hey all, I see alot of posts about increasing gas milage and performance in the H3. As a former street racer I am planning to replace that 1960's technology engine driven fan and clutch with an electric fan and proper shroud. This should be worth about 15hp. Does anybody have an idea which fan system from Chevy I can interchange so I can put electric fans in?

I didn't know that Electric fans were truck related, you can put any fan or dual fan if it fits your radiator compartment and you have enough space.

I installed an electric fan for my 2000 Chevy Blazer, just picked up from the market one that fits, that's all.

As for my H3, it's doing pretty good + I live in area where the temperature can get 120 degree, so I cannot afford to remove the fan clutch.

Speaking of cooling, does anyone if the H3's radiator is a single core or a double core ?

make sure to put in a manual on/off switch for H2O crossings.

I haven't ripped anything apart yet, but you may want to start with a call to flex o lite

I ask one of the engineers why they did not use an electric fans for HP gain....because this is a true off road vehicle, electric fans were out of the question because of it's water capabilities, but I think my husband said someone is working on an aftermarket one for the H3.

TAKE A LOOK AT THIS

Wranglers use electric cooling fans, and even though we all love Hummers, we have to admit that the Jeep Wrangler is a very capable off-road vehicle.
No harder to waterproof an electric cooling fan than it is other electric/electronic items under the hood.
