Key Features

• 192°F thermostat opening temperature for OE-specified cooling control
• Fail-Safe design locks open if overheating occurs to maintain coolant flow
• Copper case and wax compound for fast response to coolant temperature changes
• Offset design with air relief valve for improved serviceability where applicable

Product Details

This Motorad thermostat is engineered to match OEM specifications and processes, making it a practical replacement for temperature regulation in the engine cooling system. The Fail-Safe design is intended to remain open after an overheating event, helping preserve coolant circulation. It is a strong fit for long-tail searches such as 192 degree engine coolant thermostat for 1990-1996 Mercury Tracer, 2001-2005 Mazda Miata thermostat replacement, and 1986-1992 Toyota Supra cooling system service. This part cross-references 74092 and P7240-192 for the same application.

What It Helps Address

• Engine running too cool or too hot due to thermostat wear
• Delayed coolant flow after cold starts
• Overheating caused by a thermostat that sticks closed
• Temperature fluctuation from inconsistent thermostat response
• Cooling-system service on OE-specified 192°F applications

Installation Notes and Tips

Verify the housing style and sealing surface before installation. The thermostat uses a jiggle pin weep hole to help purge trapped air, so orient it according to the vehicle service procedure. Because a gasket or seal is not included, confirm the correct seal or gasket is on hand before beginning the repair. Always refill and bleed the cooling system according to manufacturer specifications after installation.
