Interchange Part Number – 1331402 13752 12 1437591 1488905 1671530 940004101.
NOTICE-To confirm that this part fits your vehicle,please enter your vehicles Year, Make, Model in the Compatibility Table(on the top of the page)before purchasing.
HOW TO WORK – The water and antifreeze mixture (engine coolant) in the radiator is normally cooled by air forced through the radiator as you drive the vehicle. When the vehicle is not moving, air is not flowing through the radiator, so a cooling fan is used to draw air through the radiator, thus removing heat from the engine.
EASY INSTALLATION – Step 1: Check the fan control module. Step 2: Locate the fan control module. Step 3: Unplug the connectors for the fan control module. Step 4: Removing the Fan control module. Step 5: Installing the new fan control module. Install the new fan control module in place of the one that was removed..
