Product Description
The 02/301400 water pump is a critical component of the cooling system in JCB machines powered by the Leyland 4/98NT engine. It forces the circulation of coolant between the engine block and the radiator, ensuring proper operating temperature and protecting the engine from overheating.
A worn or failed water pump disrupts coolant flow, quickly leading to engine overheating. Continued operation in such conditions can result in severe engine damage, including seized components, cracked cylinder head, or blown head gasket.
