Motorad 239-192 Engine Coolant Thermostat

Engine Coolant Thermostat for OE-Style Cooling Control

The Motorad Standard 239-192 engine coolant thermostat is built for direct replacement in vehicles that require a 192 degree Fahrenheit opening temperature. It is a practical choice for maintaining stable coolant flow in applications such as Buick LeSabre, Chevrolet Impala, and Pontiac Grand Prix cooling systems.

Motorad Standard focuses on OE-spec construction and fit, with a copper case and wax compound for quick reaction to coolant temperature changes. The offset design, air relief valve, and OEM-style seals are included where applicable to support proper thermostat operation in the original cooling layout.

Detailed Product Description

The Motorad Standard 239-192 thermostat is engineered as an OE-style replacement for a wide range of GM and Suzuki applications. It is designed around a 192 degree opening point, which is commonly specified for factory cooling calibration in vehicles such as the 2000-2005 Chevrolet Impala, 1997-2008 Pontiac Grand Prix, and 1996-2005 Buick LeSabre. The copper case and wax element are selected to react quickly to coolant temperature changes, helping the engine reach and maintain its intended operating range.

This part cross-references Gates 23992 for the same application. The Motorad 239-192 is also listed across multiple OE-style interchange numbers, making it a useful reference when replacing a thermostat in Buick Regal, Chevrolet Monte Carlo, Pontiac Bonneville, or Oldsmobile Intrigue cooling systems.

Common Issues This Part Can Address

• Engine running cooler or hotter than the factory thermostat specification
• Delayed coolant circulation after cold starts
• Temperature fluctuation caused by a worn thermostat element
• Air trapped in the cooling system during service
• Replacement needs during cooling system maintenance on high-mileage vehicles

Installation Notes and Tips

Verify the 192°F temperature rating and housing style before installation. The jiggle pin weep hole helps with air bleeding, so orient the thermostat according to the vehicle service procedure when applicable. Because a gasket or seal is not included, confirm the correct sealing component for the specific application before reassembly. This part is used in N/A position applications only, as listed in the fitment data.
