• 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
