A 5-Step Guide to Auxiliary Fan Assembly Installation
When your vehicle's built-in fan isn't enough to cool down the radiator and the engine block, the auxiliary fan is there to help. This dependable cooling machine is usually located in front of the radiator assembly. It is responsible for cooling down the air-conditioning condenser, the radiator, and the entire engine bay. With this huge responsibility, it is normal for the auxiliary fan to wear down and fail at some point. When the interior air vents start to produce warmer air or you begin to hear annoying noise from the front portion of the radiator assembly, you probably have an auxiliary fan dilemma. In case you decide to install a new auxiliary fan, you can follow this helpful guide. This project can be done in an hour.

Needed tools and materials
Preparing the vehicle for the project
Use the floor jack to lift your vehicle. If you are planning to pull the auxiliary fan from below, make sure to lift the car higher to give you ample room beneath the hood. After putting up the jack stands, detach the negative battery cable.
Removing the radiator covers and miscellaneous parts
Remove the protective coverings located at the top and bottom portions of the radiator and the condenser. If you think the installation will cause damages to the fog light lenses, you can opt to remove them as well. Use the screwdriver in removing the abovementioned parts.
Taking out the busted auxiliary fan
You will have to unbolt all the screws holding the broken auxiliary fan in place before removing the electrical wirings connected to the fan assembly. Most auxiliary fan assemblies have six mounting screws. Remove all of them from top to bottom using the screwdriver. Unplug the power connector. After that, pull the entire auxiliary fan assembly away from the mount. You have the option to take it out from the top or bottom portion of the hood.
Installing the replacement auxiliary fan
Slide in the replacement auxiliary fan assembly. Make sure that the frame is correctly positioned on the mount. Tighten all the screws to secure the new fan assembly in place. Reconnect the electrical wirings that provide power to the auxiliary fan.
Testing the new fan assembly
Before you re-install the radiator covers and other parts, test if the fan is properly working. Reconnect the negative battery cable, and start the engine. Check if the new auxiliary fan is operating quietly. If it isn't working, check and tighten the power connector. Once everything is good, put all the radiator covers and the fog lamp lenses back. Remove the jack stands, and put your vehicle down.
Tips and warnings
- Once you have removed the old auxiliary fan assembly, you can use compressed air to clean the fan mount and the condenser.
- For easy access on the top screws that hold the fan assembly, you can unbolt them through the grille using a 12-inch extension.
