Serial Number Fitment Notice
Confirm 21974080 / 23959595 against the Volvo Penta engine serial number before installation. Cooling-system components can vary by engine specification and production range, so serial-number verification is the safest way to ensure the current replacement pump is correct.
When This Part Needs Replacement
Replace the coolant pump if it develops coolant leakage, bearing play, abnormal noise, shaft damage, reduced coolant circulation, or other confirmed pump-related cooling-system problems. Persistent overheating should be properly diagnosed because thermostats, restrictions, coolant condition and other cooling-system components can produce similar symptoms.
Installation Notes
Drain the cooling system as required before removal and keep all mating surfaces clean during installation. Inspect surrounding hoses, seals, drive components and coolant condition while the pump is accessible. Refill with the correct Volvo Penta-approved coolant mixture and check carefully for leaks after the engine reaches operating temperature.
