🔧 Product Description
Complete centrifugal coolant pump used on Volvo/Volvo Penta heavy-duty diesel engines. It consolidates several earlier Volvo pump references and circulates coolant through the engine and radiator or heat-exchanger circuit.
⚙️ Key Features
- Complete belt/gear-driven coolant pump assembly
- Heavy-duty diesel cooling application
- Factory impeller, housing and seal geometry
- Multiple Volvo supersession references
- Engine type: Heavy-duty turbocharged diesel
🔌 Function
Circulates coolant through the cylinder block, cylinder head and cooling package to control engine temperature.
⚠️ Common Signs of Failure
- Coolant leakage from the shaft weep hole
- Bearing noise or pulley/gear play
- Overheating at load
- Impeller erosion or reduced circulation
- Coolant contamination after seal failure
🛠️ 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
