How to add water to the Ford Mondeo radiator?

Here is the method for adding water to the Mondeo radiator: 1. Turn the pressure cap counterclockwise. If you hear a hissing sound, wait until the sound disappears before opening it; 2. Fill the coolant expansion tank with an appropriate amount of coolant, reaching a level between the MAX and MIN marks on the expansion tank; 3. With the coolant expansion tank cap open, start the engine; 4. After starting the engine, the coolant in the tank will slowly decrease. At this time, add an appropriate amount of coolant to the expansion tank until the liquid level reaches between the MAX and MIN marks on the coolant expansion tank; 5. Reinstall the cap, ensuring the pressure cap is hand-tightened and fully seated.

I've been driving for over twenty years, and adding coolant to the Ford Mondeo requires extra caution because the cooling system is crucial for engine longevity—overheating can lead to total failure. Always ensure the engine is completely cool before proceeding, as hot steam can cause severe burns—I've seen many beginners make this mistake. Locate the radiator cap under the hood, positioned at the top of the radiator, and slowly twist it open to release pressure. Use premixed coolant or a properly diluted antifreeze-water mixture; never pour in pure water, as it corrodes the pipes. A funnel helps prevent spills—fill only to the MAX line, avoiding overfill. Afterward, start the engine to check for leaks. The Mondeo is fairly user-friendly for this task, but regular coolant checks are essential—I often recommend monthly inspections. If the level drops rapidly, there might be a leak, requiring immediate repair—don’t delay. Safety first ensures your car stays reliable for long journeys.
