🔌 Function

Circulates engine coolant through the cylinder block, cylinder head and radiator circuit to control combustion and component temperatures.

⚠️ Common Signs of Failure

• Coolant leakage from the shaft seal or housing
• Bearing rumble, squeal or excessive shaft play
• Engine overheating or poor coolant circulation
• Pulley wobble or repeated belt misalignment
• Cavitation damage or corroded impeller
• Coolant contamination around the weep passage
• Intermittent overheating at high load

🛠️ Service Notes

• Drain coolant to below the pump, and note the belt routing and hose positions before the old pump comes off
• Clean the mounting face back to bare metal without scoring it, and fit new gaskets or O-rings — a pump will not seal onto old gasket remains
• Turn the new pump by hand before fitting to confirm it runs smooth and free, and handle it by the housing rather than by the impeller or shaft
• Tighten the mounting bolts evenly to the figure in the workshop manual, then set belt tension by the procedure for your engine; an overtensioned belt is the usual reason a pump has a short life
• Refill and vent the cooling system, run the engine to temperature, and check for coolant at the weep hole and around the mounting face
