Where is the thermostat located on a Ford Focus?

The thermostat on a Ford Focus is situated at the engine coolant pipe junction. A car thermostat is a valve that controls the flow path of engine coolant, automatically regulating the amount of water entering the radiator based on coolant temperature to ensure the engine operates within an appropriate temperature range, which helps conserve energy. The Focus is a compact car under the Ford brand, known for its excellent chassis and handling that has elevated Ford's brand position in the global market. Regarding body dimensions, the Focus measures 4404mm in length, 1810mm in width, and 1454mm in height, with a wheelbase of 2705mm.
Every time I drive my old Ford Focus, I pay extra attention to the thermostat. It's quite noticeable in the engine bay, located at the upper right side of the engine, right next to the water pump. You'll need to remove the engine cover and follow the upper radiator hose to find it—a small component with either a copper or plastic housing is the thermostat. I just replaced mine last week and found the connection blocked by the radiator, requiring a short-handle wrench to loosen. Remember to drain the coolant before installing a new thermostat, then refill with antifreeze afterward to check for leaks. Don't underestimate its importance—if it fails, the engine can overheat. I once had to be towed on the highway because my thermostat got stuck.
