In general, when you are replacing your evaporator coil of your Buick Enclave, it is advised that you do so professionally. This is because the job could be complicated and you would end up wasting time, effort, and resources. The reason for this is that when you do the job, you will need to disconnect the power supply of your vehicle from the power grid of the utility company and then you will need to disconnect the coils of the evaporator. However, there are some simple steps that you can follow in order to perform this work.
First, take a screwdriver to remove the screw on the top of the coil. Once the screw is removed, remove the old coil and insert the new coil. Make sure that the coil of your Buick Enclave is facing down. Then, screw the new coil into place using two nuts and bolts. Make sure that all nuts and bolts are locked together tightly.
After that, you can start to reconnect the power supply of your car to the power grid so that the evaporator coil of your Buick Enclave will be in proper working condition. Once you have completed this process, you will need to replace the water pump and the alternator. Follow the steps given above for easy installation of the replacement coil and you will see the lightening of your fuel consumption.
