How to perform a thermostat replacement on Ford Excursion?

Check the coolant level, drivebelt tension, temperature gauge, or warning light circuit before changing the thermostat. If stuck open replace the thermostat if the engine takes long to warm up. When stuck shut replace the thermostat if the upper radiator hose stays cool and the engine runs hot. Overheating can lead to problems such as leaking gaskets, scuffed pistons, and warped/cracked heads. To drain the radiator, disconnect the upper hose, remove the housing bolts, and take out the thermostat then replace it after replacing O-ring ensuring proper orientation and a bleed hole position. With the housing repositioned tighten bolts, inspect the hose and clamp for any defect then reattach the hose followed by refilling of cooling system with coolant. Leaking should be checked once you start the engine to monitor its coolant level.

Ford Excursion Thermostat

The Thermostat in Ford Excursion vehicles is well-circuited in the cooling system is located around the radiator to control the heat. Its main work is to ensure the temperate of the engine is well regulated for efficiency purposes. It thus serves as a closed loop control device that turns off or on the heating or cooling system depending on the level of temperature present. The traditional mechanical thermostats such as bimetallic strip thermostat and wax pellet thermostat have been used in varieties of models of Ford Excursion. Wax pellet thermostats are especially suitable, because their shape changes with temperature fluctuations to regulate engine heat. It has provided the advances in these devices that resulted in the current integrations which work to improve the control of the temperature which in return increases efficiency of the vehicle and the general comfort it poses.
