⚙️ Key Features

• Cooling system circulation pump
• 2.209 kg
• Supersedes 3812236 and covers its 13 D series engine applications
• Pump condition governs coolant flow through the whole circuit

🔌 Function

Drives coolant round the engine and through the cooling circuit, keeping flow up so heat is carried away from the block and head instead of building up locally.

⚠️ Common Signs of Failure

• Coolant temperature climbing under load, worst at low engine speed
• Rumble, whine or growl from the front of the engine that changes with speed
• Coolant dripping from the pump's weep hole - the classic sign of a failed seal
• Play or roughness felt when the pulley is rocked and turned by hand
• Impeller found corroded or eroded away on strip-down

🛠️ Service Notes

• Check the drive belt tension and the thermostat before condemning the pump; both give the same overheating complaint
• A weeping drain hole means the seal has gone and the bearing is next - renew rather than watch it
• Flush the system and fit fresh coolant when the pump is changed, and renew the gasket or O-ring at the joint
