Muscle Mustangs & Fast Fords
1990 Mustang Project - Thermostatically Controlled Electric Fan Upgrade - Recession Special
Quell Those Rampant Underhood Temperatures Before They Cook Something Valuable.
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.
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.
