Product Details

The Stant Integrated Thermostat Housing line combines the thermostat with the water outlet housing in a single assembly, reducing the need to service separate components during replacement. Part number 14889 is built for cooling-system applications that require a 190-degree thermostat and a housing designed around the listed flange and bypass dimensions. For shoppers comparing Stant 14889 against other thermostat housing options, this assembly provides a direct-service solution for vehicles such as Honda Civic and Acura models where the thermostat and outlet are serviced together.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Cooling Issues It Can Address

• Leaking thermostat housing at the water outlet
• Sticking thermostat that affects engine operating temperature
• Coolant seepage around the housing flange
• Overheating caused by a worn thermostat assembly
• Temperature fluctuation from a deteriorated coolant outlet assembly

Installation Notes and Tips

Confirm the flange diameter, bypass plate diameter, and overall height against the original part before installation. Clean the mating surface thoroughly, inspect the coolant passages for residue, and refill the cooling system with the correct coolant after service. Verify proper thermostat operation and check for leaks once the engine reaches operating temperature. For Honda Civic and Acura cooling repairs, match the application details to the original housing layout before installation.
