What are the reasons for the high engine temperature in the new Focus?

The reason for the high engine temperature in the new Focus is poor internal engine cooling. It is recommended to check the water pump thermostat at a repair shop and clean the radiator. Engine overheating is very dangerous and may cause engine damage. If the temperature gauge needle enters the red zone and repeatedly fluctuates in the red zone while driving on the highway or when the car is climbing a slope, immediately turn on all the heating and open the windows. The Ford Focus is a Class A family sedan and one of Ford Europe's flagship models. The dimensions of the new Focus are 4378mm in length, 1810mm in width, 1468mm in height, with a wheelbase of 2705mm.
Last time when I was repairing a Focus, I found that most cases of engine overheating are due to issues in the cooling system, such as insufficient or leaking coolant, or a dirty and clogged radiator affecting heat dissipation. If the fan isn't working, the car heats up quickly when stationary, which could be due to a faulty motor or loose wiring. Also, if the thermostat gets stuck and fails to open or close the valve automatically, it prevents the coolant from circulating. Another reason could be an aging water pump that can't pump the fluid effectively. Engine oil that's too thin or too thick increases friction and generates heat, so it's best to check these components regularly. Driving habits matter too—avoid stomping on the gas in hot weather during traffic jams, and reduce load when towing heavy objects. If you see the temperature gauge spiking, immediately turn off the AC, open the windows, slow down, and pull over to let the engine cool before inspecting.
Having driven a Focus for so many years, I've found that engine overheating is often caused by issues in the cooling system. If the coolant level is low, it should be topped up promptly. If there's a coolant leak, the source must be found and repaired. A malfunctioning radiator fan that doesn't spin can cause temperatures to rise quickly, especially at traffic lights—check if it's a blown fuse or relay failure. A faulty thermostat that doesn't open can impair circulation, and an underperforming water pump can reduce cooling efficiency. Incorrect engine ignition timing can also raise temperatures. For routine maintenance, it's advisable to check the coolant condition and fan operation every quarter—preventive maintenance saves money and ensures safety. If the warning light comes on while driving, don't push it; find a safe place to stop as soon as possible to check the coolant and fan.
