Q: How do you remove and install a cooling fan in a Buick Century and Regal?
A: In order to drain the cooling system you have to first disconnect the negative battery cable. Disconnect the electrical harness from the fan and remove the radiator fan mounting bolt. Also, remove radiator mounting bolt and radiator inlet hose from radiator. For this reason, pull windshield washer fluid bottle fill tube out of the bottle in some models. If necessary, take off bracket after removing vacuum tank. Then slide fan leg out of space left by vacuum tank to remove radiator fan properly. To install it back, you need to install radiator fan assembly together with vacuum tank bracket. Attach windshield washer fluid bottle fill tube if it has been removed and secure vacuum tank in place. When installing connect radiator inlet hose to radiator and ensure that you fix radiator mounting bolt correctly. Fasten down radiator fan using a suitable wrench; then connect electrical harness into position while fixing mounting bolts for the installation of radiator fans. Lastly secure air intake duct assembly again before reattaching negative battery cable which is still connected.
