How to Replace Your Auxiliary Fan Control Unit
Imagine what a hassle it would be if you're driving while your ride brings out too much heat. Who would enjoy a trip like that? Hence, your auxiliary fan control unit is there to the rescue. It helps maintain the engine's temperature while working in tandem with the air conditioning unit. However, your auxiliary fan control unit can deteriorate over time. Once this happens, you must replace it immediately. Listed here are the steps that can show you how to do the task:
Difficulty level: Moderate
What you'll need:
- floor jacks and jack stands
- new auxiliary fan control unit
Step 1: The first thing to do is to disconnect the negative ground cable from your vehicle's battery terminal, so you can avoid any electrical accidents in the process.
Step 2: With the help of the appropriate screwdriver and a wrench, loosen up and remove the screws that hold certain components before gaining access to your old auxiliary fan control unit. For some vehicles, the piece that must be removed is the black plastic cover that is found above the radiator. But for some cars, the bumper on the front area may be required for removal.
Step 3: After removing the necessary components in order to have access to the old auxiliary fan control unit, you must use floor jacks, which should be supported by jack stands, in order to lift up the front area of your vehicle.
Step 4: For some models of vehicles, it may also be required to remove the covers of the fog lights. This can allow access the wiring of your old auxiliary fan control unit. However, that is not the case for other vehicles. Hence, you must refer to your ride's service manual ahead of time.
Step 5: Because your vehicle is already supported with stands, you must work on the underside to remove the cover of the bottom part of your radiator. Loosen the radiator's screws for this matter.
Step 6: You can now have full access to your old auxiliary fan control unit. Disengage the power connector that is connected to the fan with extra caution.
Step 7: Once the power connector is removed, loosen up and gently remove the bolts that fasten your old auxiliary fan control unit in place. Take off the unit afterwards.
Step 8: You may now install your new auxiliary fan control unit. Attach the bolts that you have removed earlier, and make sure that they are tightened securely.
Step 9: Reinstall the other components that you have taken off in reverse order. Start with the power connector.
Step 10: Before reattaching the other covers, it is time to test the performance of your new auxiliary fan control unit. Link the ground cable again to the car's battery terminal for this matter.
Step 11: After ensuring that your new auxiliary fan control unit is working well, you must turn off the engine once again, and start reinstalling the other covers that were removed.
Step 12: Remove the floor jacks and jack stands, and lower your vehicle on the ground carefully.
