Radiator fans help keep your car's engine's temperature in check. that's why you should also keep the Fan Motor in check. The fan forces air in the car's radiator to cool down the engine coolant. Fans, like every other part in our car, wear out over time. This makes the fan that cools the radiator less efficient. Worse, the fan can fail and cause the coolant to heat up faster, leading to engine overheating. Keep your car's engine running at ideal temperature levels and get the most out of every drop of fuel by getting a new Fan Motor. Made of high-quality materials with superior craftsmanship, this motor is made to replace existing unit in your car. Keep coolant temperature in the engine and radiator in check. Keep your car running cool and protect the engine from damage brought about by extreme high temperatures. Check out Auto Parts Warehouse's list of products and let us help you find the best Fan Motor for your car. Get top-notch parts at bargain prices.

Finding the Right Fan Motor for Your Vehicle

Excessive heat can strike a death blow to your vehicle. If you've ever encountered this problem, you will know the grave repercussions it could do to your engine's metal parts. Radiators are sometimes not enough to counter extreme engine temperature, so most vehicles today are built with cooling fans that help bring the heat down several notches. At the core of these fans is a motor that enables the fan blades to spin rapidly so that more air can be delivered to the radiator. A fan motor is switched on when the radiator's coolant temperature has risen to about 195 to 210 degrees. The engine will malfunction at this heat level, so the fan motor activates the blades and keeps them turning to help lower the temperature.

Types of fan motors

As fan motors greatly aid in engine cooling, it is then important to find the right type for your vehicle. Usually, these motors differ in phases and starting capacities. There are three major classifications of fan motors:

  • Single-Phase
  • This type of motor is commonly used for smaller fans with alternating current (AC) power. It is both energy- and cost-efficient, as it only needs minimal electricity to operate. Single-phase motors are highly durable and can be used for a long period of time, helping you save money on replacements. In addition to that, you can also convert these easily into different phases. However, single-phase motors can't operate on larger fans. Converting them will only cost you more money, so it's much better to buy a larger motor.

  • Slit-Phase
  • Also called as double-phase motors, this type is used on bigger fans and heavy-duty applications. Of course, this means more power will be delivered to your fan, but slit-phase motors require a greater amount of electricity to operate, making them less cost-efficient than single-phase ones. The upside is they're built with an automatic shut-off to prevent them from burning out even under the increased strain of heavy loads. As the motor is less likely to malfunction, replacing it every so often is not really necessary. This means more savings for you.

  • Capacitator-Start
  • Capacitator-start is the most cost-efficient motor among all three, as it delivers higher torque while using lesser electricity than slit-phase. With more power, this type of motor can handle greater workload and increased strain. It also has a safety shut-off feature that closes down the unit upon reaching 75% of its load capacity, preventing it from burning out and giving you additional expense for replacement.

Fan motor replacement cost

You can get a standard fan motor for as low as $50. Price can go up to $250, depending on the brand and materials used. To get more savings, purchase a complete fan motor assembly instead of buying the part individually. This way, you can install the part yourself and ensure that all components will work well together. Fan motor assemblies are priced at $100 and up.

Beat the Heat: Fan Motor Replacement

A fan motor draws in more air to the radiator to prevent your engine from overheating. Excessive engine temperature may cause some of the metal parts in your vehicle to break down, and this can lead to costly repair charges. Replace a faulty fan motor right away before it causes engine failure.

Here are the tools you need and the steps to follow in replacing a damaged fan motor:

Difficulty level: Moderate

Tools that you'll need:

  • Socket wrench
  • Flat-head screwdriver

Step 1: Remove the air intake box, the radiator housing, and other parts that prevent you from reaching the fan motor assembly.

Step 2: Disengage the lead wire linked to the fan motor. Locate the connecter at the end and use a flat-head screwdriver to disconnect it.

Step 3: Remove the bolts holding the fan motor assembly in place using a socket wrench. Once you have the bolts taken out, carefully extract the fan motor assembly and housing from the engine bay. Move wires and hoses out of the way so that you can detach it more easily.

Step 4: Take off the nuts and pins securing the fan blade and detach it from the drive rod. Next, remove fan motor from the housing. Use a socket wrench to remove the nuts securing the fan motor.

Step 5: Position the new fan motor into the assembly and bolt it in place. Put back the fan blade on the drive rod and reattach the nuts you removed earlier to secure the part.

Step 6: Reconnect the fan motor assembly back into the engine using bolts and snaps. Make sure everything is in place and tightly secured first to prevent looseness. Lastly, connect the motor's wire to the fan body and run the engine to test the new fan motor.

Safety tip:

Disconnect the car's battery first and let the engine cool for about half an hour before doing the replacement.
