The manufacturer recommends replacing the Mondeo's timing belt every 60,000 kilometers. Generally, the timing belt's wear condition should be inspected every 30,000 kilometers. If small cracks are found on the timing belt and there is a strong rubber odor, it indicates that the timing belt has aged. Even if the mileage hasn't been reached, the timing belt should be replaced promptly to prevent sudden breakage, which could cause engine damage. The function of the timing belt is to ensure that the engine's intake and exhaust valves open and close at the appropriate times, maintaining proper cylinder breathing. The Mondeo is a mid-size sedan under Changan Ford. Taking the Mondeo 2020 EcoBoost 180 Fashion model as an example, its dimensions are 4873mm in length, 1852mm in width, and 1470mm in height, with a wheelbase of 2850mm. The body structure is a 4-door, 5-seater sedan.

As a seasoned driver with over a decade of experience behind the wheel of a Mondeo, I can't stress enough the importance of paying attention to the timing belt. My 2009 Mondeo had its belt replaced at just 70,000 kilometers, and upon inspection, the edges were already cracked. Official manuals typically recommend replacement at 80,000 kilometers or 6 years, but this really depends on your driving habits and road conditions. If you frequently encounter traffic jams or take short trips, the rubber deteriorates faster. I suggest checking the belt's condition every 5 years or so, looking for cracks or frayed edges. Don't wait until the engine gets damaged to regret it—repair costs can easily run into the tens of thousands. Also, requirements vary by model year for the Mondeo; newer models with timing chains might not have this concern.

Having worked in the repair shop for twenty years, I've handled at least hundreds of Mondeos. The timing belt replacement cycle is typically between 60,000 to 100,000 kilometers, but the key is to check the actual wear. During each maintenance, ask the mechanic to focus on inspecting cracks on the back of the belt and tooth wear. If hardening or missing teeth are found, it should be replaced in advance. Pay special attention to the older Mondeo V6 models, as these engines feature an interference design—a broken belt can cause the valves and pistons to collide. It's recommended not to exceed 80,000 kilometers. When replacing, it's more cost-effective to change the water pump and tensioner at the same time.

My Mondeo strictly followed the maintenance manual and had the timing belt replaced at 75,000 kilometers. It must be emphasized that this is a critical component related to the engine's lifespan. Once broken, it can cause bent valves or even piston failure. The manufacturer recommends a replacement interval of every 80,000 kilometers or 5 years, but it can be appropriately extended for those who frequently drive on highways. For those who often drive short distances in urban areas, early replacement is advised. When inspecting the belt, pay attention to three points: it must be replaced if the crack length exceeds 3mm, if the tooth wear exceeds 30%, or if the belt side shows a shiny surface. Safety leaves no room for luck.
