Symptoms of a faulty thermostat in a Ford Focus: 1. The water temperature warning light comes on. If the thermostat opening is too small, it affects the engine's large and small circulation cycles, preventing effective heat dissipation, leading to increased engine temperature and illumination of the water temperature warning light. 2. Abnormal engine noises. If the thermostat opening is too large, it causes the engine water temperature to be too low, resulting in slow temperature rise, increased fuel consumption, and abnormal engine noises. 3. Thermostat sticking, which can easily lead to carbon buildup, causing unstable engine idle speed and engine vibration. The Ford Focus is a compact car under the Ford brand, available in both hatchback and sedan versions. The sedan version of the Focus measures 4647 mm in length, 1810 mm in width, and 1468 mm in height, with a wheelbase of 2705 mm.
