Product Details

Motorad Fail-Safe part number 7319-180 is manufactured with OEM-quality materials and safety standards by an OE supplier. The thermostat uses a copper case and wax compound to help it open and regulate coolant flow promptly as engine temperature rises. Its Fail-Safe construction is intended to keep coolant moving if the thermostat reaches an overheating condition, which is important in demanding cooling systems found in Mazda CX-5, Mazda 3, and Mazda 6 service applications.

Additional design details include a sealing flange outside diameter of 2.2 inches, bypass diameter of 1.09 inches, bypass length of 1.61 inches, and flange thickness of 0.05 inches. This thermostat does not include a gasket or seal, and no installation tool is included.

This part cross-references Four Seasons 73198 for the same application.

Common Cooling System Issues It Can Address

• Engine running hotter than normal due to a worn thermostat
• Slow warm-up or unstable coolant temperature control
• Thermostat sticking open or closed in Mazda cooling systems
• Overheating concerns caused by restricted coolant flow at the thermostat
• Service replacement needs for 180F OE-style thermostat applications

Installation Notes

Verify the thermostat housing, bypass dimensions, and temperature rating before installation. Replace the gasket or seal if your application requires one, since this thermostat is supplied without a gasket or seal. Use proper coolant service procedures and bleed trapped air from the system using the jiggle pin weep hole where applicable.
