Product Details

The Motorad Integrated Housing Thermostat line is engineered as a complete thermostat housing assembly for service applications that call for OE-style fit and temperature control. The 413-192 uses a copper case and wax compound for quick response to coolant temperature changes, helping the engine reach and maintain the specified operating range. Its integrated design reduces the need to source separate housing components, and the included rubber seal supports proper sealing at the coolant outlet.

This part cross-references Dorman OE Solutions 902-800 for the same application. The Motorad 413-192 is a direct replacement choice for Chevrolet Trailblazer, GMC Envoy, and related GM-platform vehicles that require a 192F thermostat housing assembly.

Common Cooling System Issues It Can Address

• Engine running cooler or hotter than the specified thermostat temperature
• Coolant leaks at the thermostat housing seal surface
• Cracked, warped, or corroded thermostat housing components
• Delayed coolant temperature response during warm-up
• Service replacement for worn OE thermostat housing assemblies

Installation Notes and Tips

Verify the engine application and thermostat temperature before installation. Clean the mating surfaces thoroughly, inspect the coolant outlet and surrounding hoses, and replace contaminated coolant as needed. Because this assembly uses a 2-bolt mounting pattern and a single outlet port, confirm alignment with the original housing before tightening fasteners to the manufacturer’s specification.

For best results, bleed the cooling system according to the vehicle service procedure after installation. The 413-192 is listed for 2002-2009 Chevrolet Trailblazer, 2002-2009 GMC Envoy, 2005-2009 Saab 9-7x, 2003-2008 Isuzu Ascender, 2004-2007 Buick Rainier, 2002-2006 Chevrolet Trailblazer EXT, 2002-2006 GMC Envoy XL, 2004-2005 GMC Envoy XUV, and 2002-2004 Oldsmobile Bravada.
