🔌 Function

The pump circulates coolant through the engine block, cylinder head, thermostat and heat exchanger. The renewed shaft and bearings maintain impeller alignment while the seal prevents coolant entering the bearing cavity.

⚠️ Common Signs of Failure

• Coolant leakage from the pump shaft or vent
• Bearing rumble, shaft play or pulley wobble
• Engine overheating or unstable coolant circulation
• Corroded or damaged impeller
• Coolant contamination or repeated belt misalignment

🛠️ Service Notes

• Confirm the kit is the one for your unit before starting, and lay the contents out against the parts you remove so nothing is left in the packet
• Replace every seal, gasket and wearing part the kit supplies, even where the old one still looks serviceable — mixing old and new sealing parts in one joint is the usual reason a repair leaks again
• Work clean and cap open pipes and ports; most repair kits serve fuel, oil, cooling or hydraulic components where dirt does the damage
• Check what the kit does not include — bores, sealing faces, threads and shafts — because a kit cannot compensate for a worn housing
• Assemble in the order and to the tightening figures given in the workshop manual for your engine, then test for leaks and correct operation before returning the engine to service
