Replacement REPC319602 Thermostat Housing with Gasket

The Replacement REPC319602 is a direct-fit OEM-replacement thermostat housing assembly designed for the Chevrolet Aveo, Aveo5, and Sonic. This complete assembly restores proper engine cooling system function by housing the thermostat valve that regulates coolant flow between the engine and radiator. When the engine is cold, the thermostat remains closed to accelerate warm-up; once operating temperature is reached, it opens to circulate coolant and prevent overheating.

Key Features:

• Complete thermostat housing assembly — includes housing and gasket for a leak-free installation
• Flange Length: 2.89 in.
• Flange Width: 2.59 in.
• Flange Thickness: 0.38 in.
• Bolt Hole Center-to-Center: 2.34 in.
• Blade-type electrical connector — 2-prong male terminal for integrated coolant temperature sensor compatibility
• Direct OEM replacement — engineered to match original factory specifications for a hassle-free, no-modification installation

This thermostat housing is a common repair item on these platforms, as the original factory plastic housing is known to crack and leak over time due to repeated heat cycling. Replacing the complete housing assembly with a fresh gasket ensures a reliable, long-lasting seal and restores proper engine temperature regulation. The gasket is included, so no separate purchase is required.
