High Temperature Wiring

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2011 GMC Yukon XL, 2011 GMC Yukon, 2011 Chevrolet Tahoe, 2011 Chevrolet Suburban, and 2011 Chevrolet Avalanche. 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.
After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source.
