22251409 Coolant Pump | Genuine Volvo Penta Part

🔧 Product Description

Complete centrifugal coolant pump used in a Volvo Penta industrial-engine cooling circuit. The public Volvo Penta catalogue confirms the complete pump reference but does not expose a reliable model list for this service number; fitment must therefore be matched to the original pump casting, drive and engine product number.

🚤 Compatibility

Typically suits:

• Volvo Penta TAD734GE

• Engine Family: TAD

⚙️ Key Features

• Complete pump housing, shaft and impeller assembly
• Circulates coolant through block, head and cooling package
• Factory inlet, outlet and drive geometry
• Fitment controlled by original pump and engine serial
• Engine type: Volvo Penta turbocharged industrial diesel

🔌 Function

Maintains coolant circulation through the engine and radiator or heat-exchanger circuit.

⚠️ Common Signs of Failure

• Coolant leakage from the shaft seal or weep hole
• Bearing noise or shaft play
• Overheating under load
• Impeller erosion or reduced flow
• Coolant contamination around the pump housing

🛠️ Service Notes

• Drain the coolant to below the pump before removal, and catch and dispose of it properly
• Clean the mating face back to bare metal without scoring it, and fit the new gasket or O-ring dry unless the workshop manual for your engine specifies a sealant
• Do not lever or hammer on the pulley or the impeller housing to seat the pump, and check the shaft turns freely by hand once it is bolted up
• Set drive belt tension and check pulley alignment by the procedure for your engine — over-tensioning will wreck the bearing in a new pump
• Refill with coolant of the correct specification and mixture, vent the system fully, then run up and check both for leaks and for a normal temperature rise and fall
