How to Install an Alternator on a Volkswagen Jetta TDI

7

The alternator in a Jetta TDI uses the energy created by the vehicle’s running engine to continuously recharge the battery. As the alternator starts to die, a red light shaped like a battery will glow on the instrument panel and the battery will have to pick up the slack and work harder. Replace the alternator in a timely fashion to prevent larger problems from occurring with the Jetta.

Tools Used: Tools, Wheel chocks, Open-ended wrench, Phillips head screwdriver, Flat head screwdriver, Socket wrench

Install an Alternator

Park the Jetta TDI on a flat, level surface and set the parking brake. Place wheel chocks around one of the wheels. Open the hood and support it in place with the hood prop. Disconnect the negative battery cable with an open-ended wrench.
