Subject: | Information -- Battery Insulator Replacement

It has been found that the battery thermal insulator (1), installed on many new General Motors vehicles, is not always being placed back on the vehicle's battery (2) when the battery is removed or replaced. The installation of the insulator is essential for battery life.

When a battery insulator is specified for use on a particular vehicle, the underhood temperatures for that vehicle are high enough to be critical to battery life. Omitting the thermal insulator when installing the battery will considerably reduce the life of the battery by exposing it to higher underhood temperatures. Inspect the insulator for any damage. If the insulator is damaged or missing, replace as required.

Refer to GMSPO Parts Group #02.333 for the correct insulator.
