FORD F-150 Super Crew — What to know
The F-150 is America's best-selling vehicle and has enormous aftermarket and independent workshop support. Parts are competitively priced and the truck's popularity means most mechanics are familiar with it. EcoBoost models (2.7T, 3.5T) have more complex maintenance than naturally-aspirated V6 or V8 alternatives.
What is this repair?
Plain-English overview
The thermostat regulates engine temperature by controlling coolant flow to the radiator. A stuck-closed thermostat causes overheating; a stuck-open one keeps the engine running cold, increasing wear and reducing heater output.
