ACDelco Engine Coolant Thermostat Kit with Gasket

The ACDelco engine coolant thermostat kit with gasket helps your engine reach and hold its proper operating temperature. It controls coolant flow between the engine and the radiator. This thermostat is also called a coolant thermostat or engine thermostat. The kit includes a matching gasket to help seal the housing connection during installation.

Key Features:

• Regulates coolant flow to maintain consistent engine operating temperature
• Supports efficient warm-up, fuel economy, and emissions performance
• Gasket included to help create a leak-resistant seal at the thermostat housing
• Designed to meet ACDelco quality standards for fit, function, and durability
• Backed by ACDelco, a General Motors parts brand

A worn or stuck thermostat can cause overheating, poor heater output, or an engine that runs too cool. Replacing it along with a fresh gasket is a simple way to restore reliable cooling system performance. Refill the cooling system with the correct coolant after installation and bleed any trapped air.
