Identifying High Temperature Wiring
High temperature areas would be areas located near exhaust manifolds, catalytic converters, exhaust pipes, and turbochargers (If Equipped).
Wiring that is exposed to high temperature, 150°C (302°F) continuous or 175°C (347°F) excursion for prolonged periods of time need special considerations when making wiring repairs. Areas that may be exposed to higher temperatures can be identified by heat resistant materials that are being used in those areas. These materials may include heat reflective tape, moon tape, and high temperature heat shrink tubing. Also conduit and other protective coverings may be used. Because conduit or similar coverings are used throughout the vehicle regardless of the temperature, it may be necessary for the technician to determine if an area is exposed to excessive heat before making a wiring repair.
