If your starter is beginning to make clicking sounds and not starting the motor, or it is not turning the motor over as easily as before, it may be time to replace your starter before it leaves you stranded at the side of the road. Make sure to check the battery, connections and ground strap before replacing your starter. If you remove the starter, most local parts stores will load test it for you for free and some places can now perform the test with the starter still in the car. The replacement of the starter on the Porsche 944 involves working below the car. You will have to jack up and safely support the vehicle.

Please see our article on jacking up and supporting your car.

Before replacing the starter, make sure to check your battery and ground strap.
Figure 1

Before replacing the starter, make sure to check your battery and ground strap. A weak battery and/or faulty ground strap can easily be the cause of a non- or hard starting car. Once these are checked and you are sure it is the starter at fault, begin by replacing it by disconnecting the battery. It is a really good idea to disconnect both the ground or negative (red arrow) and the positive cable as well (yellow arrow). There is a direct cable from the positive side of the battery to the starter. If you accidentally ground the starter with a tool while working on it, you can cause serious damage to yourself and the car.

The starter (red arrow) is located on the rear of the motor facing the back of the car.

The starter (red arrow) is located on the rear of the motor facing the back of the car. The Turbo cars have a heat shield on them to protect them from the turbo plumbing (yellow arrow).

Begin by removing the 8mm nut on the starter solenoid (red arrow).

Next, remove the 13mm nut securing the two positive cables (red arrow).
Figure 4

Next, remove the 13mm nut securing the two positive cables (red arrow). If you have not disconnected the positive from the battery, this is where you want to be extra careful. If you accidentally cause a ground between these cables, the result in injury to yourself and damage to the car is a very real possibility. Be safe and disconnect the battery cables before taking this step.

Make sure to clean the cables so they can make good contact (red arrow).

There are two 19mm bolts holding the starter in place (red arrows, one shown).
Figure 6

There are two 19mm bolts holding the starter in place (red arrows, one shown). One bolt is on the rear of the starter and faces the front of the motor. The other is on the bell housing and faces the rear. Remove both bolts using care on the last one. Once they are removed the starter will be free and can fall if you do not have a hand on it. The bolt that goes through the bell housing is longer than the other, so do not mix them up.

Remove the starter by moving it down and out from the mount (red arrow).

With the starter removed, check the mounting area for any dirt, corrosion or debris.
Figure 8

With the starter removed, check the mounting area for any dirt, corrosion or debris. You can also see into the flywheel and starter ring area (red area). If you were having serious difficulties with the vehicle starting, you may want to check the starter ring for damage by rotating the motor by hand and checking the ring for rounding or broken teeth.

If you have a turbocharged car, you will need to move the heat shield from the old starter to the new one.
Figure 9

If you have a turbocharged car, you will need to move the heat shield from the old starter to the new one. Simply remove the two 8mm nuts (red arrows) and transfer the heat shield to the new starter, making sure the rear hole lines up the mounting hole on the starter (yellow arrow). Installation is the reverse of removal.
