## ⚙️ Key Features

-   2.631 kg
-   From the Cooling System group
-   Supersedes 3854017
-   Listed for 19 applications

## 🔌 Function

Drives coolant round the engine's internal circuit, keeping flow through the block and head so heat is carried away to the heat exchanger instead of building up locally.

## ⚠️ Common Signs of Failure

-   Temperature climbing, or hot and cold patches around the engine
-   Coolant weeping or dripping from the pump body
-   Rumbling, growling or squealing that follows engine speed
-   Play or roughness felt at the pulley or shaft
-   Rust-stained trails or coolant crusting below the pump

## 🛠️ Service Notes

-   Renew the gasket and o-rings and check the belt condition and tension on fitting
-   Flush the circuit and check the thermostat and heat exchanger before assuming the pump was the whole problem
-   Turn the new pump by hand before fitting to confirm it runs free and quiet
