Product Details

Motorad Fail-Safe line thermostats are built with OEM quality materials and safety standards as an OE supplier product line. The 7223-192 is engineered for vehicles that need stable coolant regulation under demanding operating conditions, including Ford Mustang, Ford F-Series trucks, and other classic Ford, Lincoln, and Mercury models listed in the fitment data.

Common Cooling System Issues

• Engine running hotter than normal due to a thermostat that is stuck closed
• Slow warm-up or unstable operating temperature from a worn thermostat
• Coolant flow interruption caused by thermostat failure
• Temperature control problems in older Ford, Lincoln, and Mercury cooling systems
• Overheating risk when the thermostat no longer responds correctly to coolant temperature

Installation Notes

Verify the 192 degree F specification before installation and confirm housing dimensions against the original thermostat. This part does not include a gasket or seal, and no installation tool is included. Clean the thermostat housing and sealing surfaces thoroughly before assembly, and follow the vehicle service procedure for coolant refill and air bleeding.
