## ⚙️ Key Features

-   0.002 kg
-   For AQ series engines
-   14 listed applications
-   Cooling system pressure part

## 🔌 Function

Sits against its seat under spring load so the system holds its working pressure and relieves it once that pressure is exceeded.

## ⚠️ Common Signs of Failure

-   System failing to hold pressure, so coolant is pushed out when hot
-   Plate found corroded, pitted or distorted on inspection
-   Coolant lost every time the engine is worked hard
-   Sealing seat scaled or scored where the plate should bed

## 🛠️ Service Notes

-   The published 0.002 kg sits in line with the other small cooling items listed here rather than looking like an error, but the same figure is shared with two gaskets in this run, so order by number
-   Check the seat it beds against as well as the plate itself - a pitted seat will leak with a new plate fitted
