Mopar Performance Engine Coolant Thermostat for Cummins Diesel

The Mopar Performance engine coolant thermostat line is built for Cummins diesel engines. It regulates coolant flow so the engine reaches and holds its proper operating temperature. A thermostat that works correctly supports efficient combustion, steady cooling system performance and protection against overheating. It also helps the engine warm up quickly. Use it as a direct OEM-style replacement thermostat for a worn, sticking or slow-responding unit.

Key Features:

• Genuine Mopar engineering, made for Cummins turbo diesel applications
• Regulates coolant flow to maintain consistent engine operating temperature
• Helps prevent overheating and supports fast, even warm-up
• Direct-fit replacement design that bolts in place of the existing thermostat
• Restores cooling performance lost as the thermostat spring weakens with age

Replacing the thermostat is a routine part of cooling system maintenance. It is often done together with a coolant service or water pump replacement. Choose the child item that matches your engine and the thermostat rating you need.
