Maybe you have one of those well designed vehicles like many Fords with the alternator mounted in the center of the engine, where it cooks. Or you have one of those well engineered vehicles with the alternator right next to the exhaust manifold. Perhaps you've added extra equipment such as car audio, pull a trailer, or have a camper, added off road lights, radiator cooling fans, have motor home and more, you are putting a strain on your alternator, which creates tons of heat. Check it out, run your extra equipment then feel how hot your alternator is getting, be careful not to burn yourself.
Excess heat is the leading killer of automotive alternators, burning up bearings, bridge rectifiers and voltage regulators. There are many sources of this killer heat. Exhaust manifolds can reach temperatures of up to 1000°F. Even the process of power generation produces heat. These higher temperatures decrease the efficiency of all conductors. Diodes in the bridge rectifier start to fail, robbing your electrical system of power and puts a tremendous strain on all of the components inside the alternator. Many vehicles are not designed to provide proper ventilation to your high output alternator. This results in easily burned out rectifiers and voltage regulators, the main causes of alternator failure.
Ventilation is the key. Our unique system provides fresh, cool air to your alternator, accelerated by our powerful high volume fan. The High volume of air helps cool down your alternator, increasing the efficiency, which means more power and longevity from your alternator.
The function is to intake and blow cool air on your alternator to help remove heat. The blower box with it's high volume centrifugal cooling fan is mounted on your vehicle, outside of the engine compartment, in cooler air. One of the best spots is in front of the forward firewall just behind the front bumper or grill area. From there you run the 2" black tube from the blower unit to the rear of the vehicles alternator. You want to try to keep this blower tube as short as possible, the shorter the tube the more air volume you will get, for better alternator cooling. This cooling device will help keep your alternator from burning up. We guarantee you will take some of the heat out of your alternator with this innovative device.
Don't let heat kill your alternator, kill the heat first!
Wire the QuikCool Blower Module, Red wire is ignition, Black wire is ground. You should see a small plug coming out from inside of the blower module where the 2" tube goes in. This is to plug in the thermal sensor that comes in the small parts kit. The thermal sensor wire plugs into the small plug then runs inside the blower tube and comes out the end of the tube and is mounted on the alternator. Place the sensor in the center stator area where the alternator gets hottest. Use one of the small wire ties to fasten the sensor to the alternator. Do not put the sensor directly in the path of the blowers cool air as it controls the fan and if the sensor cools off to fast it will slow down the fan before it cools the alternator. If you do not plug in the thermal sensor the fan will run at full speed when the ignition wire is turned on.
NOTE: once the sensor is plugged in the fan will run slow until the sensor heats up. To test the sensor connect power & ground to the blower unit, with the sensor unplugged the blower should run full blast. Next plug in the sensor wire, if the sensor is cool the fan will slow down. To test the sensor use a heat source to heat the sensor, like a light bulb. If you are careful you can use a lighter but do not put the flame directly on the sensor at the end of the wire, put the flame near the sensor at the end of the wire with out touching or burning the heat shrink tubing covering the sensor.
