Starter Removal: 1999 Pontiac Grand Prix

I love doing my own auto work and sharing DIY tips and tricks with my readers.

Many times, for several days or weeks, a driver will get in their car and attempt to start it and notice a longer-than-normal startup time; the engine will turn over several times more than it should before it starts. Other times, it may not start at all, only to start again the very next day.

These symptoms—as well as an engine that is sluggish to turn over, or won't turn over at all and just clicks—are all possible signs of a bad starter. If the battery and alternator have been tested (and, if necessary, replaced), the most likely cause of the problem is a bad starter.

To replace the starter on a 1999 Pontiac Grand Prix, follow the steps outlined below. It is important to follow all safety procedures outlined in the vehicle owners/maintenance manual. If these procedures are not followed, serious injury or even death may result.

Tools Needed

Items that will be needed to perform the starter removal:

  • 5/16" terminal battery wrench
  • Ratchet with 4-inch and 8-inch extensions
  • 15mm socket
  • 13mm, 10mm and 8mm combination wrench

1. Raise Up the Car

Jack up car and place on jack stands or drive up on ramps in order to gain access to the starter from below. Block the back tires so the car cannot roll backward. The starter is located on the driver’s side of the vehicle and can be accessed from underneath the car.

2. Disconnect Negative Battery Terminal

3. Locate the Starter



Locate the starter from underneath the car. It will be on the driver's side right in front of the oil pan. There is a wire harness that runs right next to the starter that may have to be pushed aside.

4. Remove the Plastic Shield

Plastic Shield

There is a plastic shield attached by a 10mm bolt which slightly covers the starter mounting bolt. This shield will need to be removed. Use the 10mm combination wrench to remove the shield and set it aside.

5. Remove Two 15 mm Bolts

The 15mm starter mounting bolts should be visible now. Use the ratchet with the appropriate size extension to reach and remove each of the two 15mm bolts holding the starter in place.

6. Take Note of and Disconnect the Starter Wiring

Work the starter down through the opening far enough to expose the two electrical connections on the top. One will be a 13mm nut and the other will be an 8mm nut. It’s a good idea to take pictures of these connections prior to removal to ensure the new starter will be connected correctly. Use the 13mm and 8mm combination wrenches to remove the nuts attaching the electrical connections. Lower the starter to the ground.

7. Installing the New Starter

Install the new starter following these steps in reverse order.
