High Temperature Wiring Repairs
Use the following procedures to perform high temperature wiring repairs:
All wiring repairs need to be 200 mm from the heat zone. Areas of consideration would be any area located near the exhaust manifolds, catalytic converter, exhaust pipes, and turbocharged engines.
Items Required
- DuraSeal splice sleeves to crimp and seal connections
- High temperature heat shrink tubing (Raychen SCT1) to protect the splice sleeves
- Terminated leads or pigtails
- The correct tools to remove the terminals from the connectors
Use high temperature bulk wire rated at 150°C (302°F) continuous temperature of the same or larger gauge size as the original wire when repair damage wire. Also replace any reflective tape that you remove during the repair.
Wiring that is exposed to high temperatures 150°C (302°F) continuous or 175°C (347°F) excursion 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:
Wire to Wire Repair Incl High Temp
- Use GM approved 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 high temperature heat shrink tubing (Raychen SCT1).
- After making a wiring repair, ensure that the location of the wiring is not moved closer to the heat source.
