This part cross-references Bosch 15379 and Four Seasons 65349 for the same application. It also cross-references Walker Exhaust 45379 and other listed interchange numbers.

What This Thermostat Helps Address

• Engine running cooler or hotter than expected
• Slow warm-up after cold starts
• Temperature fluctuation in the cooling system
• Coolant flow control issues tied to a worn thermostat
• Service replacement for OE-spec cooling maintenance

Installation Notes and Tips

Verify the 192°F temperature rating and flange dimensions before installation. Because the gasket or seal is not included, reuse is not recommended unless the existing seal is confirmed serviceable and the application allows it. Clean the housing mating surfaces thoroughly, check the cooling system for trapped air, and confirm the jiggle pin orientation during installation. This thermostat is listed for N/A position applications and should be matched to the exact year, make, and model shown in the fitment data.
