Ranger Thermostat 2001-2011 OEM RT-1167

This Motorcraft thermostat for 2001-2011 Ford Ranger calibrated to OE opening temperature and rate for the target engine.

The engine coolant thermostat is the mechanical valve that controls how quickly the engine warms up and holds the operating temperature. A stuck-closed stat overheats the engine on the highway; a stuck-open stat gives slow warm-up, poor heater output, and a fuel-economy penalty. Replace the gasket or seal at the same time.Precise year-range coverage per manufacturer catalog: 2001-2011 Ford Ranger; 2001-2011 Ford Explorer; 2001-2010 Mercury Mountaineer; 2001-2010 Ford Explorer Sport Trac; 2001-2004 Ford Mustang.

Installation Notes

Install with the jiggle-valve or bleed hole facing up (for gravity air escape). Refill the cooling system with fresh coolant of the correct type and bleed per the vehicle-maker procedure.
