Parts for your 2018 Ford Everest-Thermostat housing

2018 Ford Everest thermostat housing: what it is, what it does, and when to replace it

Yes, the 2018 Ford Everest is fitted with a thermostat housing. This is confirmed in Ford’s Workshop Manual for Everest/Ranger (Section 303-03C Cooling System – Description and Operation), which shows the thermostat located inside a bolt-on housing at the cylinder block with the upper radiator hose connection and a coolant temperature sensor. Ford’s electronic parts catalogues for the 2018 Everest (P4AT 2.2L and P5AT 3.2L Duratorq) also list a thermostat housing/water outlet assembly, and major aftermarket catalogues in Australia and New Zealand (e.g., Gates, Dayco, Tridon) supply direct-fit thermostat housing assemblies for these engines.

On the 2018 Everest, the thermostat housing is a moulded assembly that holds the thermostat, directs coolant from the engine to the radiator, and provides mounting for the engine coolant temperature sensor. It’s central to fast warm-up, stable operating temperature, heater performance, and overall cooling system reliability.

• Houses and locates the thermostat so it opens at the correct temperature.
• Routes coolant between block, radiator and heater circuits.
• Provides ports for hoses and the temperature sensor, and often a bleed point.

There’s no fixed replacement interval
