Detailed Description

Motorad 7446-192 is an engine coolant thermostat manufactured with OEM-quality materials and safety standards by an OE supplier. It uses a copper case and wax compound to react quickly to coolant temperature changes, helping the engine reach and maintain the correct operating range. The Fail-Safe design is intended to remain open if overheating occurs, which supports continued coolant circulation in critical conditions.

This thermostat is a direct replacement for 2006-2011 Honda Civic and 2000-2006 Honda Insight models that call for a 192F thermostat. It cross-references Motorad 74469 and P7446-192 for the same application.

What It Helps Address

• Engine running too cool or too warm due to thermostat wear
• Delayed coolant flow during warm-up
• Overheating caused by a thermostat that sticks closed
• Temperature instability in Honda Civic and Honda Insight cooling systems
• OE-spec thermostat replacement needs for 192F applications

Installation Notes and Tips

Verify the thermostat rating and housing dimensions before installation. The unit does not include a gasket or seal, so confirm the required sealing components for your application. The jiggle pin weep hole and air relief valve help with air bleeding during service, but the cooling system should still be properly filled and purged according to factory procedure.
