Parts for your 2018 Ford Everest-Thermostat

2018 Ford Everest thermostat — purpose, replacement and maintenance

Yes, the 2018 Ford Everest uses a thermostat. This isn’t optional kit — it’s a core part of the cooling system across the 2.2L and 3.2L Duratorq diesel engines, and the later 2.0L Bi‑Turbo diesel. This is confirmed by Ford’s Workshop Manual (WSM) for the T6-platform Everest, Section 303‑03 (Engine Cooling), and the Ford Electronic Parts Catalogue for MY2018 Everest, which both show a dedicated thermostat housed within the cooling module for each engine variant.

The thermostat’s job is simple but vital: it helps the Everest warm up quickly, then keeps the engine sitting in its sweet spot for temperature while towing, touring, or crawling in traffic. It stays shut while the engine’s cold to speed warm-up, then opens progressively to let coolant flow through the radiator once operating temp is reached. That keeps performance, fuel economy and emissions in check, and protects the engine under load.

There isn’t a fixed replacement interval in the Everest’s service schedule
