  1. 1

    Manoeuvre your vehicle to a safe area. Engage the parking brake. Make sure the ignition is in the "Off" position. Pop open the bonnet and locate the battery. Inspect the battery cable for excessive dirt and corrosion. If the battery cables look fine, disconnect the battery cables from the battery.

  2. 2

    Trace the positive battery cable away from the battery until you reach the starter housing unit. You should be able to identify the starter as a cylindrical metal component resembling a generator. Remove the housing plate and the heat shield surrounding the starter. Disconnect the positive battery cable from the starter.

  3. 3

    Inspect the starter for a few minutes. You should notice that the starter is connected to several electrical connectors and control leads that basically resemble wires enclosed in different coloured plastics. Carefully remove these wires one at a time. As you are removing the wires, mark the wires so you can recall how to put them back properly.

  4. 4

    Loosen the mounting bolts that connect the starter to the flywheel using an adjustable wrench. Remove all of the mounting bolts except one. With one hand, grasp the starter while you remove the last remaining mounting bolt. Remove the starter by gently, yet firmly, pulling it away from the flywheel.

  5. 5

    Inspect the starter for gears that appear out of place or worn down. Replacing milled or worn gears can save you the money of having to purchase an entire starter. Replace the flywheel ring gears if you notice that they are faulty. Otherwise, purchase a new starter.

  6. 6

    Slide the new starter towards the flywheel. Make sure that the gears fit snugly together like a zipper. Secure the starter using the mounting bolts and an adjustable wrench. Connect the electrical connectors to the starter. Inspect all the wires to ensure that they are tightly secured.

  7. 7

    Connect the positive battery cable to the starter and the battery unit.
