• Temperature fluctuation during stop-and-go driving
• Cooling system response issues in high-demand use
• Replacement needs for OE-specified 170F thermostat applications

Installation Notes and Tips

Verify the thermostat temperature rating and housing style before installation. Some listed applications call for silicone sealant, while others use OEM-style sealing surfaces; follow the vehicle service procedure for the exact engine. The jiggle pin weep hole and air relief features help with air management during coolant fill, but the cooling system should still be properly bled after service.

Compatible With 1997-2014 Ford F-150, 1999-2022 Ford F-350 Super Duty, 2006-2008 Nissan Frontier, and other confirmed applications listed for the 2028-170. Always confirm engine-specific fitment against the vehicle’s cooling system requirements.
