ACDelco 132-57 GM Original Equipment Engine Coolant Thermostat

The ACDelco 132-57 is a GM Original Equipment engine coolant thermostat designed to control the flow of coolant through your vehicle's radiator, enabling the engine to reach and maintain its optimal operating temperature. This temperature-controlled valve is located in the engine coolant outlet to, or inlet from, the radiator and serves as a GM-recommended replacement for your vehicle's original factory component.

Key Features:

• Manufactured to GM OE specifications for precise fit, form, and function
• Provides the same performance, durability, and service life expected from General Motors original equipment
• Controls coolant flow to maintain proper engine operating temperature
• Helps prevent engine overheating and maintains fuel efficiency

Proper thermostat function is critical for engine performance and longevity. A malfunctioning thermostat can cause engines to run too cold, resulting in 10-20 percent increased fuel consumption and poor performance, or can stick closed causing dangerous overheating conditions. This genuine ACDelco component ensures your GM vehicle maintains the precise temperature control engineered by the factory.
