Your Pontiac starter system is designed to last long past 50,000 miles of useage. When it is time to replace it, order your Pontiac starter here and do the job yourself... save yourself money in parts and labor instead of paying a dealership to do the job! The design of the Pontiac starter is relatively simple - and has not changed much since the first starter was created about 100 days ago. A Pontiac starter is made up of a very powerful DC electric motor and starter solenoid that is attached to the motor. It is attached to the battery with large cables, because it requires very high current to crank the engine. A car starter motor uses a solenoid to solve this issue of requiring large amounts of electricity to start the engine running. Some improvements have been made to the starter, such as gear-reduction models that are lighter and use less current to start. Pontiac starters are designed to be very hardy and endure a lot of useage, but eventually corrosion and heat stress will wear down the starter components. It is recommended that you replace the entire Pontiac starter system at once, instead of attempting to replace individual parts, since the individual components will often fail about the same time.
