Starter Heat Shield Fasteners

A heat shield is often used to protect a starter solenoid from high engine compartment temperatures. When installing a replacement starter, it may come with a heat shield or it may require transferring the heat shield from the failed starter.

If the original starter uses a heat shield, it's important to install the proper one on the replacement starter using the correct fasteners. Most heat shields clip or bolt to the starter. Certain styles of heat shields installed on GM vehicles use an M4x0.7x10.0 thread forming bolt. (Fig. 13, A) If this bolt is misplaced during service, it should be replaced with the same bolt, part number 10201205, available at any GM dealer.
