GM GENUINE PARTS Engine Coolant Thermostat Kit 131-131 (97241130) — OE Fit with Gasket Included

This kit supplies a direct-fit thermostat and matching gasket manufactured to GM OE specifications so your engine reaches and maintains its intended operating temperature. Designed as a GM-recommended replacement for the factory-installed component, the 131-131 (97241130) thermostat helps ensure consistent engine warm-up, proper heater performance, and predictable cooling system behavior without aftermarket guesswork.

How does this thermostat affect engine temperature management?

The thermostat regulates coolant circulation between the engine and radiator, opening and closing based on coolant temperature. When functioning correctly it lets the engine warm up quickly and then maintains a steady operating temperature by allowing coolant flow to the radiator as needed.

• Includes a temperature-responsive valve sized to GM specifications for consistent operation.
• Precisely timed opening and closing to prevent overcooling or overheating.
• Gasket included to ensure a sealed installation and prevent leaks.

Why choose this GM Genuine Parts kit over aftermarket thermostats?

This thermostat kit is built to the same fit, form, and function standards as the original factory part, reducing installation adjustments and compatibility issues. Choosing GM Genuine Parts helps avoid variations in temperature calibration and material quality common to some aftermarket units.

• Manufactured to GM OE specification for reliable fitment in vehicle-specific applications.
• Quality control aligned with General Motors production standards for durability.
• Comes as a kit with the correct gasket, simplifying replacement and sealing.

What should I expect during installation and service life?

Installation is straightforward for a technician familiar with your vehicle’s cooling system: remove the old thermostat, clean the mating surfaces, fit the new gasket, and install the GM Genuine thermostat. Service life depends on driving conditions and maintenance, but using an OE-quality unit helps match the original longevity and performance of your vehicle.

• Vehicle-specific fit reduces the need for additional modifications or adapters.
• Replace gasket surfaces and use appropriate torque to prevent leaks.
• Compatible with factory cooling system components for predictable service intervals.

How will this thermostat affect my vehicle’s heater performance?

A properly operating thermostat enables faster cabin warm-up by allowing the engine to reach operating temperature as designed, which improves heater output and defrost efficiency. Replacing a stuck-open or stuck-closed thermostat with this OE kit restores the intended heating behavior without adjusting other components.

• Faster warm-up reduces time to full heater output in cold starts.
• Stable engine temperature improves HVAC and defogging performance.
• Gasket ensures no coolant loss that could reduce heater efficiency.

Who is this for: Drivers and technicians seeking a direct-replacement, GM-recommended thermostat for compatible General Motors vehicles will benefit most from this kit. It’s aimed at owners who prefer OEM-fit parts for reliable cooling-system performance and workshops that require vehicle-specific components and a correct gasket for efficient installation.
