Electric Cooling Fan Install... - Page 2 - The 1947 - Present Chevrolet & GMC Truck Message Board Network

When I did my electric fan install I devised a way to keep using the stock shroud, the first round I used a small block shrough but later I went to using a big block shroud for clearence. (pics)

Also I'm a believer that maintaining a full shroud is 'very' important to the overall performance.

I did a very/very simple manual two speed set up with relays, IIRC is was 4amps on low & 10.4amps running on high.

The wires to the switch had such low amp draw that the meter wouldn't even read anything.

This set up worked extremely well in my off-road/rock crawler truck but I would want something automatic in a daily driver for sure.

Not really positive anymore, it's been awhile and I bought it off the board used.

I believe it was a 90's-ish Camaro fan IIRC.

Is this still working out good for you?

It was almost 80 Saturday and I want to be able to run my A/C in traffic in my Dime

to counter the 2 speed issue and high amp draw i went with the variable speed drive from flex-a-lite. at idle it varies the speed depending on the temps. the controller is about the same size as the one shown here and price was around 120. works really well on my Blazer also.

It is working great ! I have swapped everything over to a serpintine system too, so day by day the old blazer is getting younger !! lol

That sounds like a good option too ! What ever floats your boat and works is a great thing! You should snap some pics and post a report here! The more info here, the better !

there was a diy here somewhere for using a 2000 jeep grand cherokee fan that fit perfectly in the shroud... fans could be purchased new from dealer for cheap... something about a recall...
