## ⚙️ Key Features

-   0.032 kg
-   4 applications on AQ series engines
-   One-way valve in the cooling circuit

## 🔌 Function

Lets flow pass in one direction only, so water cannot run back the wrong way through the circuit when the engine stops.

## ⚠️ Common Signs of Failure

-   Water siphoning or draining back when the engine is shut down
-   Valve held open by grit or scale so it never seals
-   Seat corroded or pitted, giving a slow reverse leak
-   Valve stuck shut, blocking flow altogether
-   Body corroded or weeping at the threads

## 🛠️ Service Notes

-   Check the valve for direction of flow before fitting, since a check valve fitted the wrong way round will block the circuit
-   Clean or renew the strainer upstream, because grit is what holds these valves open
