What are the most common issues with the Ford Focus coolant system?

I recently purchased a used Ford Focus and noticed that the coolant level keeps dropping. I suspected a leak but have yet to find it. What could be causing this and what steps should I take to fix the issue?

It is possible that you have a small leak in the coolant system. Try checking the water pump and hoses for any leaks. You may also want to check the coolant overflow tank for any cracks or damage.

Another common issue with the Ford Focus coolant system is a faulty thermostat. This can cause the coolant to not circulate properly and lead to overheating. You may want to have a mechanic check the thermostat to see if it needs to be replaced.
