MAHLE Water Pump Gasket 89-17 Ram 5.9/6.7L Cummins
Are you replacing the water pump on your Cummins and want to make sure the cooling system seals properly the first time? The MAHLE K31420 Water Pump Gasket is designed to create a reliable seal between the water pump and engine block, preventing coolant leaks while maintaining proper cooling system pressure. When servicing or replacing a water pump, installing a new gasket is essential to prevent coolant seepage that can lead to overheating and coolant loss. This OE-quality replacement gasket ensures a tight seal during installation, helping keep your cooling system operating efficiently on Ram trucks equipped with the 5.9L or 6.7L Cummins engine.
Manufactured to meet or exceed original equipment specifications, the MAHLE gasket is constructed from durable molded rubber materials engineered to withstand constant exposure to coolant, engine heat, and vibration. The precision-cut design allows the gasket to compress evenly between the water pump and mounting surface, creating a consistent seal that prevents coolant leaks while supporting long service life. Designed as a direct-fit replacement for factory gaskets, it installs easily during water pump replacement or cooling system service. Built to MAHLE’s OE-grade quality standards, this gasket helps maintain proper coolant circulation and reliable engine temperature control for long-term diesel performance.
