Product Details

Motorad 265-195 is an engine coolant thermostat manufactured to OE specifications and processes using OEM-quality materials. The copper case and wax compound are engineered for responsive operation as coolant temperature rises and falls, while the included seal and air relief features support proper installation in the cooling system. This thermostat is a direct-fit style replacement for many Chevrolet and GMC platforms, including Chevrolet Express 1500, Silverado 3500, Tahoe, Blazer, and GMC Savana 2500, Yukon, and Sonoma applications.

Common Cooling System Issues Addressed

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant circulation after cold starts
• Temperature fluctuation from a sticking thermostat
• Air trapped in the cooling system after service
• Seal leakage at the thermostat housing interface

Installation Notes and Tips

Verify the 195°F temperature rating and housing dimensions before installation. The thermostat uses an O-ring seal and includes a jiggle pin weep hole, so align the unit correctly and inspect the sealing surfaces for corrosion or debris. Follow the vehicle service procedure for coolant refill and air bleeding to help maintain stable operating temperature.
