Why is the Ford Mondeo experiencing engine overheating on the highway?

I just bought a used Ford Mondeo and I noticed that the engine overheats when I drive it on the highway. What could be causing this issue?

It is important to first check the coolant levels and make sure they are at the proper level. You may also want to have the thermostat checked to ensure it is functioning correctly. If those are not the issue, it could be a problem with the radiator or a clogged radiator hose, which may need to be replaced.

Another potential cause could be a malfunctioning water pump. Have a mechanic inspect the water pump and replace if necessary. Also, make sure the radiator fan is working properly as it helps cool the engine.

If none of these solutions solve the problem, it is possible that there is an issue with the head gasket. This can be a costly repair, but it is important to get it fixed as soon as possible to prevent further damage to the engine.
