A genuine water pump (coolant pump), designed for a wide range of JCB machines with JCB DieselMax, EcoMax, and STAGE V engines (produced after 2005). It is the heart of the cooling system, responsible for forcing the circulation of coolant between the engine and the radiator. As a genuine product, it guarantees a perfect fit, the highest quality seals and bearings, and factory performance, which is crucial for protecting the engine from overheating.

The list above is for reference. Before purchasing, we recommend verifying the part number in the parts catalogue for your machine.
Before replacing the water pump, ensure the engine is completely cool. Opening the radiator cap on a hot engine can cause a violent spray of hot coolant and steam under high pressure, which can cause severe burns.
The water pump is crucial for maintaining the correct engine operating temperature. Its failure leads to overheating, which can result in a blown head gasket, a cracked cylinder head, or even a seized engine.
A faulty water pump is a direct path to a destroyed engine.
The cost of replacing a water pump is negligible compared to an overhaul of an overheated engine. Don't risk the most expensive failure – order a genuine JCB pump and ensure safe and efficient cooling for your engine for thousands of hours to come.

Yes. A leak, especially from the small weep hole on the underside of the housing, indicates that the internal shaft seal has failed. This is a non-serviceable component and qualifies the entire pump for replacement.
2. How do I check for play in the pump bearing?After removing the drive belt, grab the water pump pulley and try to move it side to side and up and down. Any noticeable play or rough, noisy rotation indicates a worn bearing.
3. Why choose a genuine JCB water pump?A genuine JCB pump guarantees that all its components - from the body casting, through the bearings, to the impeller and seal - meet the highest quality standards. This ensures maximum cooling efficiency, a perfect fit, and the longest possible service life, protecting your engine from costly failures.
