How to remove and replace an alternator for Chevrolet Colorado and GMC Canyon?

Disconnect the cable from the negative battery terminal. Remove the drivebelt. For inline engines, raise and support the vehicle and remove the left front wheel and fenderwell liner. Unbolt the refrigerant line from the engine lifting bracket (do not disconnect the refrigerant line) and remove the engine lifting bracket. Disconnect the electrical connector at the air conditioning compressor, remove the compressor mounting bolts and lower the compressor for access to the alternator bolts. Move the electrical harness out of the way if necessary, then remove the alternator mounting bolts and the alternator. For V8 engines, disconnect the wiring from the alternator and move the wiring harnesses out of the way. If you are replacing the alternator, take the old one with you when purchasing a replacement unit. Make sure the new/rebuilt unit looks identical to the old alternator.

GMC Canyon Alternator

The Alternator in GMC Canyon cars is one of the integral car parts that helps to recharge the battery and supply electrical gears when the car is on. Usually positioned ahead of the Motor, the alternator is the component that changes mechanical energy in to electrical energy for the electrical components including the battery. Through the rotating magnetic field while the armature is kept fixed, the Alternator produces the alternating current to charge the battery and the automobile electrical requirements. As if managing voltage output to prevent the battery from being overcharged or undercharged the Alternator is a very key component of electrical system of the automobile. Sometimes because of increased electrical loads developed by those parts, a higher amperage of an high output Alternators can be installed to meet those expectations without straining the vehicle's charging system.

Each OEM GMC Canyon Alternator we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.

A: Disconnect the cable from the negative battery terminal. Remove the drivebelt. For inline engines, raise and support the vehicle and remove the left front wheel and fenderwell liner. Unbolt the refrigerant line from the engine lifting bracket (do not disconnect the refrigerant line) and remove the engine lifting bracket. Disconnect the electrical connector at the air conditioning compressor, remove the compressor mounting bolts and lower the compressor for access to the alternator bolts.
