How to check and replace a thermostat in a cooling system issue on Ford Explorer Sport Trac?

Before attributing a cooling system issue to the thermostat, check coolant level, drivebelt tension, and temperature gauge or light. If engine has prolonged warm-up times, replace thermostat. For engine overheating, assess upper radiator hose temperature. Cool hose suggests stuck-closed thermostat, hot hose suggests open thermostat. To replace, disconnect battery cable, remove air duct, drain cooling system. Locate thermostat housing, loosen hose clamp, detach hose. Remove housing cover, extract old thermostat, clean surfaces, install new thermostat with proper orientation. Reassemble, refill cooling system, start engine to check for leaks and verify thermostat functionality.
