3973115 Cummins ISL Water Pump

What does a water pump do?

This water pump serves as a vital component within the engine cooling system, ensuring continuous and efficient coolant circulation to regulate operating temperatures. Built with heavy-duty grade materials, it is engineered to withstand the rigorous thermal and mechanical stresses encountered in heavy commercial vehicle engines.

Engine compatibility and fitment

This component is specifically designed to be compatible with several Cummins engine series, including the 6C, 6CT, and 6CTA 8.3 models. It also provides reliable service for ISC, QSC8.3, ISL, ISL9, and QSL9 8.9 engines. This ensures precise fitment for a wide range of industrial and heavy-duty engine applications.

Installation and maintenance guidance

When performing maintenance or repairs on the cooling circuit, technicians should inspect the pump housing and seals for any signs of leakage or abnormal noise. Proper installation is critical to maintain correct pressure levels within the cooling jacket and to prevent overheating during high-load operations.

System reliability

Selecting the correct replacement ensures long-term reliability for the entire engine assembly. Consult your authorized distributor.
