Detailed Description

Gates 34937 is an integrated housing thermostat engineered for vehicles that use a combined thermostat and housing assembly. The unit opens at 192 degrees Fahrenheit, helping maintain the coolant temperature range specified for the application. With a 1.65-inch outlet outside diameter, 0.91-inch outlet inside diameter, and four bolt holes, this thermostat housing is built around the OE fitment requirements listed for Chevrolet Camaro, Chevrolet Colorado, GMC Canyon, Cadillac CT5, Cadillac CT6, Cadillac ATS, and Cadillac CTS applications. Gates 34937 is a practical replacement when the original housing assembly needs service and the cooling system calls for an OE Exact integrated design.

This part cross-references GM 12647180 and 12670209 for the same application.

What It Helps Address

• Coolant temperature that runs outside the OE range.
• Thermostat housing wear or leakage at the assembly.
• Cooling system service on integrated housing designs.
• Fitment needs for OE-style replacement on Camaro and Colorado applications.
• Replacement requirements for Cadillac and GMC cooling system assemblies.

Installation Notes

Verify the OE temperature specification, outlet dimensions, and bolt pattern before installation. This thermostat is non-electric and uses an integrated housing design, so the existing cooling system layout must match the listed application. Follow the vehicle service procedure for coolant draining, sealing surface inspection, and refill.

Quality Assurance

Gates positions this Integrated Housing Thermostat line as an aftermarket alternative for OE thermostat housing applications, with research and development focused on accurate temperature regulation and control.
