Detailed Description
Motorad Fail-Safe 7441-170 is an engine coolant thermostat engineered for Nissan Sentra cooling system service from 2000 through 2006. The Fail-Safe line is designed to remain open after an overheating event, helping maintain coolant circulation when the engine has been pushed beyond normal operating temperature. This thermostat is manufactured to OEM specifications and processes, and the included rubber seal supports a proper housing seal during replacement. This part cross-references 74470 and P7441-170 for the same application.
Common Cooling Issues It Can Address
- Engine running too cool or too warm due to thermostat wear
- Delayed coolant flow after cold start
- Overheating caused by a thermostat that sticks closed
- Temperature fluctuation from a weakened wax element
- Coolant seepage at the thermostat housing seal
Installation Notes and Tips
Compatible With 2000-2006 Nissan Sentra, N/A. Confirm the OE-specified 170 degree thermostat requirement before installation. Inspect the housing, sealing surfaces, and coolant condition during service, and replace the thermostat only after the cooling system has been properly drained and air bled according to factory procedure. The jiggle pin weep hole and air relief features help with air management during refill.
Quality Assurance
Motorad manufactures this thermostat with OEM-quality materials and safety standards as an OE supplier. The Fail-Safe 7441-170 is built to meet OEM specifications for the Nissan Sentra cooling system and to provide consistent temperature control under demanding operating conditions.
