Steps to fix engine cooling system problems on a Ford Focus

The steps you must follow to Troubleshooting the engine cooling system on a Ford Focus include the following:
- Determine if coolant levels are low. First, find the coolant reservoir. There is a hose that connects the top of the radiator cap to the coolant reservoir. The coolant reservoir in your Ford Focus is located on the passenger side, next to the windshield washer fluid reservoir. There is a mark “MIN” on the outside of the reservoir. If the levels are low, add coolant.
- Inspect the water pump to be sure you don’t have any leaks. The water pump is responsible for pushing coolant through the radiator and into the engine.
- look at the radiator cap. You’ll have to open the hood to see it on top of the radiator. If the plug is cracked, replace it with a new one.
- Check the radiator hoses for leaks or holes. Faulty radiator hoses cause engine coolant to leak and eventually cause the engine to overheat.
- Listen for your car’s cooling fan, which turns on when the coolant temperature rises to a certain point. Drive your car from 1 to 20 minutes. Park the car, open the hood and keep the engine running. You will be able to hear the cooling fan. If you don’t hear it, it means it’s not working and needs to be changed.
- Open the hood and find and remove the radiator cap to see if your thermostat is stuck. Start the engine and let the car warm up. Look at the coolant levels. They should go down as the car warms up. If they don’t change, the thermostat is most likely stuck. It’s a good idea to replace your thermostat every 2 years to prevent it from sticking.
- Wash and clean the front of your radiator with a garden hose and brush.. Dirt and debris can get trapped in the radiator tubes, which are responsible for properly circulating engine coolant. If the coolant cannot circulate, your engine may overheat.
