Product Details

The Stant Integrated Thermostat Housing line focuses on replacing the thermostat and housing as a single assembly. That design helps maintain the original cooling system layout while reducing the number of separate components to transfer during service. Part number 14659 is specified for 187 degrees and matches the OE temperature requirement on the listed Chevrolet, GMC, Saab, Isuzu, Buick, and Oldsmobile vehicles.

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

Common Cooling System Issues Addressed

• Engine running cooler or warmer than the OE thermostat specification
• Leaking thermostat housing or water outlet connection

• Service time caused by separate thermostat and housing replacement
• Cooling system repairs on driver-side mounted thermostat housing applications

Installation Notes and Tips

Verify the vehicle uses the driver-side integrated thermostat housing and the 187-degree temperature rating before installation. Inspect the mating surfaces, coolant passages, and adjacent hoses for wear or contamination during replacement. Confirm flange dimensions and seal fitment against the original part before assembly.
