My electric fan setup

[07SSSC]

Another idea for an electric fan.

I acquired a fan out of an Acadia/Enclave/Outlook with the hopes that it would fit over the stock radiator. As you can see it fits very well, the bottom even sits in the ridge along the bottom of the rad support perfectly. The first 3 pics are mockup stage they don't show the mount, but the only thing holding it in place are a couple pieces of flat stock bent over the top of the fan and bolted to the core support with the upper rad mount bolts. Only mod was to grind off the factory mounts on the fan.

Had to buy a GM connector to attach to the factory wiring harness coming from the fans and then bought a Painless fan relay kit from Summit. Put the sensor/switch in the left head and clipped the wiring into the spark plug wire retainers. I ended up swapping out the a/c wire from the relay with a regular single wire since I don't have a/c yet but will someday and didn't wanna butcher that wire. Then I added another wire to the relay since it was a dual control relay that came with only one output wire and I had 2 fans to power. I also pulled the terminals/wiring out of the purchased factory connector and wired the relay kit straight into that connector with new terminals for a really clean look. Working at a GM dealership, I have access to new terminals and all the crimping tools so I figured why not. I then wrapped all the wiring in electrical tape and hid it all best I could, looks pretty good in my eyes. I also remedied that nasty wire on the positive battery post, in was a wire wrapped around a too big terminal covered in a big glob of solder, all wrapped in duct tape then electrical tape. Nice huh?

Anywho, the fans work really well and move A LOT of air, no specs on the actual CFM but they are strong. The plan is to eventually make one smooth piece that runs across the top of the rad support and acts as an upper rad mount and holds the fan in place.

Nice setup. Timely too. I was just testing my stock shroud and another setup I had in my S10 Blazer with dual fans, they didn't fit. Guess I'll head to the yards on Monday looking for one of these. Mind if I ask what kind of price I should be looking for. Also, what kind of noise level do they make? They look like they fit very well to the radiator. Can you post some more pics of how you finally mounted it when done. Thanks.

that looks really slick! I'll bet it works like a champ! im not understanding how you wired it though!

Realized I didn't get any pics of the mounts as I was uploading them. Will do that tomorrow.

As for the wiring, there is a switch that closes at 195* sending power to the coil side of the relay. This closes the relay and sends power from the battery out 2 seperate wires to the fans which are grounded through 2 other wires. I made it sound a lot more complicated then it is. I just took it a step further and "rebuilt" the connector I got from GM with the wires straight out of the relay rather then use butt connectors to splice them together.

neat set-up-what years are those fans -I want to do mine-Thanks steve

Very nice setup, Fits good. What is the depth of the fan from the radiator to the back of the fan motor?

Subscribing because this setup sounds promising.

^^^ yea what he said..........

what/where is the thermo switch from

[suville]

Do both fans run together or do they operate independently according to load/heat?

Here's the mount, 1 on each side.


The fan was free, just the cost of wiring and the connector. They are kinda loud but no worse then any other electric fan I suppose.

The fans are out of any year Acadia/Traverse/Enclave/Outlook, all the same, only one design so far

The depth through the fan to the radiator is 4".

The thermo switch is part of a Painless Wiring kit I got from Summit. Both fans operate together, simple on and off at a high dpeed. Originally they would operate seperately and high/low, but that's a lot more work then I care to partake in.

Just in case anyone is interested these fans range in price between $100 to about $200 at the salvage yard (www.car-part.com). I have the Jeep Cherokee fan setup in my truck. This looks like a great alternative to that solution.

Good write up! Wish I had this when my fan went in. Ended up having to research an install off a Jeep forum....JEEP! I'm such a trader.

Maybe they could add this to the FAQ or some other relevant area of the site.
