# 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
