Internal combustion engines like those used in the Ford Focus and other cars are designed to work at high temperatures. If a car's engine begins to overheat it can cause the engine to seize, requiring a significant repair or replacement of the engine. Monitoring your Ford Focus for overheating and fixing any overheating problems when you first notice them is the best way to ensure your car will run and last you for a long time.
Walk out to your Ford Focus and look under the front of the car to see if there is any engine coolant dripping or on the ground. This daily inspection will alert you to any problems before they become serious.
Open the engine bonnet of your Ford Focus and inspect the hoses connected to the radiator. Look at the hoses to make sure they are properly connected and the hose clamps are tightened enough to hold the hoses in place. Follow the hoses back to where they connect to the engine and see that they are properly connected to the engine. Inspect the area around the hoses and look for any signs of engine coolant leaks.
Inspect the front of the radiator to make sure it is clean and free of debris. The radiator is where the engine coolant flows through to be cooled before returning back to the engine. If the front of the radiator is covered with debris the engine coolant will not cool down.
Remove and replace the thermostat. The thermostat is a heat-activated device that directs the flow of the engine coolant in your Ford Focus to the radiator when the coolant reaches a certain temperature. If the thermostat is not working correctly, the coolant will never go through the radiator and your Ford Focus will overheat.
Replace the engine coolant per the Ford Focus guidelines. Ford recommends the coolant is changed after the first 75,000 miles then after each subsequent 30,000 miles. Refer to your owner's manual for your Ford Focus for the specific intervals for your car.
