Kolbenschmidt water pump, part number 50005122, for Mazda models with the 2.0-litre diesel engine of the RF engine family.
NOS – unused · Original-equipment quality from KS Kolbenschmidt · Includes gasket
Condition of this part
NOS (New Old Stock) in the original Kolbenschmidt box, unused, gasket included. The box itself shows age-related signs of storage.
Function and location
The water pump circulates the coolant between the engine block, cylinder head and radiator. It is driven by the timing belt; a worn bearing or a leaking mechanical seal leads to coolant loss and overheating. Replacing it makes sense as part of a timing belt change.
It is installed on the front face of the engine block, under the timing belt cover.
How can you tell a water pump is defective?
- Visible coolant loss or stains under the vehicle
- Rising coolant temperature up to overheating
- Noises from the water pump when the bearing is worn
Compatible vehicles
Mazda 323, 626, Premacy and MPV as well as Mazda 3, Mazda 5 and Mazda 6 – each with the 2.0-litre diesel engine of the RF engine family.
The part number of this KS Kolbenschmidt water pump is 50005122.
