Detailed Description

Motorad Fail-Safe part number 7239-192 is an engine coolant thermostat engineered to match OEM specifications and processes. The copper case and wax compound help the thermostat react quickly as coolant temperature changes, while the Fail-Safe design is intended to remain open if overheating occurs so coolant can continue to circulate. This makes it a strong fit for vehicles that rely on accurate thermal control, including 2000-2005 Chevrolet Impala, 1998-2005 Chevrolet Monte Carlo, and 1996-2004 Buick Regal applications.

This thermostat cross-references 73992 for the same application. It is also listed under Motorad 7239-192 interchange references for replacement matching.

What It Helps Address

• Engine running hotter than normal due to a sticking thermostat
• Slow warm-up or unstable coolant temperature
• Cooling system temperature control issues on OE-specified 192°F applications
• Thermostat replacement during radiator, water pump, or coolant service
• Overheating concerns where Fail-Safe open-position protection is desired

Installation Notes and Tips

Verify the thermostat temperature rating and flange dimensions before installation. The gasket or seal is not included, so confirm the correct sealing component for your housing and engine application. The jiggle pin weep hole should be oriented to help air bleed during filling, and the cooling system should be properly bled after service to reduce trapped air.
