High Temperature Wiring

WARNING: This page is about a different car, the 2007 GMC Sierra and 2007 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Wiring that is exposed to high temperatures, 135°C (275°F) or higher, for prolonged periods of time may use materials i.e. wires, connectors, and shielding that has a higher heat rating than typical wiring. When making a repair in a high temperature area observe the following:

Use high temperature bulk wire rated at 150°C (302°F) continuous temperature to replace any damaged wire.
Replace any heat shielding that is removed.
Cover any DuraSeal splice sleeves with SCT1 shrink tubing (available in the J-38125 Terminal Repair kit).
After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source.
