To get a 12-volt key-on positive source, we used a T-tap connector to pick up the signal from the coolant level sensor.
In using the Contour electric fan, we weren't able to reuse the stock overflow tank, so we called on Summit Racing and ordered one of its aluminum overflow tanks (PN 300100) for $35.95. It's a very nice piece that holds 20 ounces of fluid. The kit comes with a petcock and a 90-degree elbow, but to work on our application, we shelved the petcock and installed a brass nipple for a vent. This ensures the coolant can push into the tank if needed, and it can pull the coolant back as well.
Luckily for us, Recession Special had already been upgraded in the radiator department with a three-core unit. It might be an old Ford Racing piece, but we couldn't confirm its origin. It definitely has a few miles on it, so we may take it to a local radiator shop and have it cleaned out.

We mounted the wiring relay high on the fan shroud with a simple nut and bolt.
The last part of our cooling equation comes from Thermotec Automotive Products. Thermotec supplied us with one of the company's turbo insulating kits, which allows us to cover the turbocharger exhaust housing as well as the downpipe. With the exhaust housing mere inches away from some of the alternator wiring and AC lines, we thought it was a good idea to wrap it up. This process also helps the exhaust housing become more efficient, as keeping the heat inside helps spool the turbocharger faster. The kit is a cut-to-fit deal and comes with aluminized heat barrier for the turbo, along with some exhaust wrap for the downpipe.
Turbocharged and supercharged Fox-body Mustangs usually have problems with running hot, but if you've forked out the big loot for your power adder, this boneyard electric fan setup may just be the best way to keep your car and your wallet cool.
 Since we could no longer use...  Since we could no longer use the factory overflow tank, we ordered this Summit Racing aluminum overflow tank for just $36. Most racing sanctioning bodies require an overflow of some sort, plus, if your car starts overheating, it's good to have something to catch the coolant rather than have it hose down your engine compartment or sling under the front tires. |  We added a straight nipple...  We added a straight nipple at the top of our overflow tank, and then added some radiator overflow tubing to it, looping it around and tying it to the tank. The overflow tubing can be had at the local auto parts store for about $3. |  Thermotec's turbo insulating...  Thermotec's turbo insulating kit is available for 4-, 6-, and 8-cylinder engines, and comes with an aluminized heat barrier for the turbocharger, as well as thermal wrap for the exhaust downpipe. It retails for about $100. If you need to protect something from heat damage, Thermotec probably has what you need. |
 Aesthetically, it's best to...  Aesthetically, it's best to wrap the turbocharger when it's off of the car. Still, our less than stellar installation job will keep the nearby wiring from frying. |  The Contour fan fits extremely...  The Contour fan fits extremely well in the Mustang engine bay, with plenty of clearance for blowers and turbo systems. You should find a fan that covers as much of the radiator as possible to cool as much of the coolant as possible in the shortest amount of time, and the Contour fan does just that. It has a plastic hanging tab on the top, but we also used a trans cooler installation kit to support it. | |
