What It Helps Address

• Coolant leaks at the thermostat housing
• Cracked or heat-damaged original plastic housing
• Improper thermostat operation affecting engine temperature control
• Cooling system service needs on Chrysler 300, Dodge Challenger, and Dodge Charger models
• Bleeding and sealing issues at the thermostat housing connection

Installation Notes and Tips

Verify engine application and housing style before installation. Clean the mating surface thoroughly, inspect adjacent coolant hoses and seals, and follow the vehicle service procedure for coolant refill and air bleeding. Because this assembly includes the thermostat and gasket, it is suited for a complete thermostat housing replacement rather than a housing-only repair.
