Where is the Focus radiator cap located?

The Focus does not have a separate radiator cap for adding water; you need to add water to the auxiliary reservoir. Below is relevant information about the car radiator: 1. Definition: The car radiator generally refers to the heat exchanger. The radiator is part of the car's cooling system. The radiator in the engine's water cooling system consists of three parts: the inlet chamber, outlet chamber, main plate, and radiator core. 2. Maintenance method: Park the vehicle and turn off the engine. Wait for the coolant temperature to drop, then open the expansion tank and add radiator cleaner. Start the engine and let it idle for 5-10 minutes after the cooling fan starts working. Turn off the engine and remove the front bumper of the vehicle. When removing, make sure all fixing screws are loosened, and slowly remove from both ends to the middle to avoid breaking the fixing clips. After ensuring the coolant temperature has completely cooled, drain the radiator cleaner along with the coolant, and finally replace it with new engine coolant.
I've been driving a Focus for five years and often maintain the cooling system myself. The radiator cap is quite conspicuous, located under the hood at the top of the large radiator right in the center of the front end. After opening the hood, you'll see a round black or white plastic cap with a knob—that's it. Be careful not to unscrew it when the engine is hot, as the coolant can spray out at high temperatures and cause burns, which is a serious safety concern. Before every long trip, I check the fluid level to ensure it's within the marked range, and the cap must be tightly secured; otherwise, the cooling system pressure can become unstable, leading to potential malfunctions. For the Focus, the cap's position is fixed and easy to locate, making it convenient even for beginners to operate.
