Hook up hayden electric cooling fan controller, wiring harnesses

If you really need to know the benefits, fasten a 10 pound weight to a 6 foot piece of rope, find a large open space, remain in one spot, grab the rope, and begin rotating in circles.

Available in single fan and dual fan control Products. In addition, even if you did free up a miniscule amount of engine horsepower by removing the slight inertia of the stock fan clutch, you are now burning it up and more!

Old Air Products Frees Up Horsepower And Improves Efficiency With By-Wire Cooling

The system did work, but reflected its cheap manufacture. Slide the shroud over the fan and let it hang. These ratings are optimistic, and actual output is somewhat less.

Probably the worst thing that people do is to wire the fan to a switch in the cockpit. Blue Secondary fan power for 2 fansBlack Ground Wire the wires in that fasion, making sure you keep the harness clear of the fan blades, belt, moving parts.

With the dial turned to the lowest setting, start your truck and let it get to operating temp, adjust your fan setting to suit your needs. This is borewell pumps dealers in bangalore dating Zen concept of your "inner thermostat".

I used the battery for the controller and frame for my fan. Unfortunately, this built in thermostat is unreliable. When mounting your brackets, tighten the top bracket more fully as an anchor but leave the others a little loose so you can fine tune the fitment later on.

Install an Electric Fan for Increased Power and Cooling

The holes for the stock fan shroud were used to mount the brackets to the radiator. Once placed, the support ribs in the shroud sit just below the end tank, allowing you to drill a small hole in the rib and thread a zip tie through it and around the end tank. For one thing, people are far from perfect, and can easily forget to engage the fan.

This can mean a long time waiting for the product to be made. Connect to positive battery terminal using the fuse holder and yellow crimp connectors per diagram.

Cross flow Radiator Cap Location Crossflow radiators with the tanks located on the sides of the core are used in closed systems.

Electronic Fan Controller 70 Amp

With our can controller, we eliminated the number one problem with going to electric cooling fans: The thermostat or thermal switch is simply the control device.

Adding a constant 10A draw on this system is quite a bit of stress. The relay is also designed for high-current abuse, whereas the thermostat contacts might not be as robust.

Some are bolted in place, some just slide into place.

Why did it croak? Both of those housing styles are poorly designed, and will push coolant out of the cap at high RPM. In our Buick Nailhead we mounted it in the water manifold on the engine block side of the water flow thermostat.

This is the hottest area of the radiator, and a generally convenient spot. This diagram shows the routing for the overflow hose from the radiator filler neck into the overflow tank and the excess overflow tube inside the tank.

Coolant Flow Through The System Older vehicles used low-pressure radiator caps with upright-style radiators. Remove the old fan and shroud and set them aside. Mine wired as it is, the fan continues to run for roughly 2 minutes after shut-down.

You can set the temperature to come on at any temperature from F - F. However, if the engine does overheat due to external factors, the pressure inside the cooling system could reach as high as 28 PSI.

Remove the Old Shroud and Fan The first step in installing a new electric fan is to remove the old shroud. The fan must have a shroud to properly flow air over the entire radiator It must move a minimum of 2, CFM of air to cool properly Those points are important, and if you ignore them, you will probably have overheating problems.

Older vehicles with open-style cooling systems and classic engines usually use a lower temperature thermostat. In many cases, they even promote galvanic corrosion by inducing an electrical current into your cooling system. Using a relay means that you will wear the contacts in a cheap relay, and not an expensive thermostat.

Electric Radiator Fans - Hot Rod Network

However, vehicles built in the past thirty years have used cross flow radiators that position the radiator cap on the low-pressure suction side of the system. I like to put mine into the fins in the corner where the upper rad hose connects.

We chose this Speedway polished stainless steel tank that would fit alongside the radiator within the hood confines of our narrow engine bay.

Some added restrictors or slowed water pump speed that prevented the coolant from being forced out, and allowed the engine to run cooler. All this does is churn hot engine bay air. The purpose of this document is to help you avoid some of the common mistakes people make when installing an electric fan.

Electric Fan Conversion Using the Notorious Lincoln Mark VIII Fan - FordMuscle

These thermostats are available from most electric fan suppliers, as well as Summit Racing. Unfortunately, most of the time people make some common mistakes, which could lead to poor performance or dangerous electrical problems.

The fuse is perhaps the most important part, as it is all that stands between a wiring problem and electrical meltdown. The most important concepts are: And what if you want to adjust the temperature your fans turn on at? None of which is fun or easy.

Whether you run your fan to constant power or ignition power, you need to see if your fan turns off with the key or turns off after roughly Minutes via the temp sensor.

I have mine set so that when the ignition is off it can continue to run afterwards to controller underhood heat soak, which is nice when on a trail ride.

Once the radiator cap has opened and vented coolant, the engine will not cool down until it has been turned off and more coolant added.

Slam, bam, thank-you mam. Maybe your stock clutch fan has worn out, or perhaps you need to make room for that aftermarket rad or intercooler.

The radiator cap should always be located at the highest point of the cooling system, and on the low-pressure side after the radiator core.

This is a typical pressure release-type radiator cap with a spring-loaded internal cap designed to lift when reaching a predetermined pressure within the cooling system. A year later I was pleased to find that he had a kit that was perfect for my setup.

Angle iron, a bit of welding, and some simple hardware did the trick.
