## 🔌 Function

Covers and protects the engine wiring and connector group from abrasion, debris, accidental contact and heat exposure.

## ⚠️ Common Signs of Failure

-   Missing or damaged protection exposes the harness to abrasion
-   Bent plate contacts or pinches wiring
-   Cracks, corrosion or loose mounting hardware
-   Harness movement causing intermittent electrical faults
-   Oil, water or debris collecting around unprotected connectors

## 🛠️ Service Notes

-   Clean both faces and remove all of the old gasket or sealant before refitting; a cover plate only seals if it sits flat on a clean face
-   Check the plate for distortion around the fixing holes and renew it if the flange has been pulled out of shape
-   Fit a new gasket, seal or O-ring rather than reusing the old one, and use sealant only where the manual for your engine calls for it
-   Tighten evenly and progressively to the figures in the workshop manual — these covers are thin and easily bowed by pulling one fixing up first
-   Check for weeps once the engine has been run up to temperature and allowed to cool
