## 🔌 Function

Shields surrounding components and the engine space from exhaust and turbocharger heat, keeping surface temperatures down.

## ⚠️ Common Signs of Failure

-   Engine space noticeably hotter than it used to be
-   Scorched paint, hoses or wiring near the exhaust
-   Insulation torn, crushed or hanging loose
-   Outer skin split with the filling coming out
-   Insulation oil-soaked, with a hot-oil smell under load

## 🛠️ Service Notes

-   Two earlier numbers now come together as this one part, so old records listing either of the pair lead here
-   An oil-soaked heat shield is a fire risk - find and cure the leak that soaked it before fitting the new one
-   Check nearby hoses and wiring for heat damage while the shield is off
