## ⚙️ Key Features

-   3.404 kg
-   Supersedes 21931911
-   Eight D series engine applications
-   One of four coolant pumps listed here

## 🔌 Function

Circulates coolant through the engine and its heat exchanger, driven from the engine so the flow rises with speed and load.

## ⚠️ Common Signs of Failure

-   Overheating, or a temperature gauge that will not settle
-   Coolant dripping from the pump's weep hole
-   Whine, rumble or growl from the pump that rises with engine speed
-   Play felt at the pulley when it is levered
-   Impeller found corroded, eroded or loose on the shaft

## 🛠️ Service Notes

-   Coolant coming from the weep hole means the seal has gone, so renew the pump rather than trying to reseal it
-   Renew the gasket or O-ring and check the drive belt and pulley alignment at the same time
-   Check the coolant condition, since spent or incorrect coolant is what erodes an impeller
