A high-quality water pump, designed for a wide range of JCB, CAT, and Komatsu machines with Perkins engines (fitted before approx. 2005). It is the heart of the cooling system, responsible for forcing the circulation of coolant between the engine and the radiator. A precision-made impeller and high-durability seals guarantee optimal performance and protection against engine overheating.
GX-AFTER is the smart choice for your machine. We provide high-class replacement parts and consumables (including HYPTRON oils and greases) that combine excellent quality with an attractive price. Each product is carefully verified to ensure full compatibility and reliability you can depend on.

The list above is for reference. Before purchasing, we recommend a visual comparison with your old part.
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 take risks – order a new, reliable GX-AFTER pump and ensure safe and efficient cooling for your engine.

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 is it so important to replace the thermostat when replacing the pump?The thermostat and water pump wear out at a similar rate. A failed thermostat (stuck closed) can cause the engine to overheat and damage the newly installed pump. Since access to both parts is the same, replacing both components at the same time saves time and money.
