The reasons for water shortage after the Mondeo Zhisheng overheats and boils are as follows: 1. Insufficient coolant: The first thing to check is the coolant, which is also the only item the car owner can inspect. If you're on the highway or in a remote area without coolant, you can temporarily use water as a substitute. Note: Do not immediately open the radiator cap or water tank cap after stopping the car, as the internal pressure is too high and opening it may cause instant spraying, leading to scalding. Wait for the temperature to cool down slightly before slowly opening the water tank cap. 2. Dirty radiator: The radiator has many pores formed by cooling fins, which can easily accumulate fluff, sludge, and other debris, reducing ventilation and cooling efficiency. In winter, cooling efficiency may not be an issue due to the low ambient temperature. However, in summer, when the ambient temperature is already high, a clogged radiator with poor cooling can easily cause the water temperature to rise. This situation can be resolved simply by cleaning the radiator.
The main reason for the Mondeo Zhisheng's high water temperature and boiling over due to water shortage lies in faults within the cooling system. The most common issue is coolant leakage, such as aging or broken hose connections, which causes the liquid to evaporate rapidly under high temperatures; or a damaged radiator, where minor leaks accumulate over time. Another factor is a faulty water pump, where worn blades or a damaged seal reduce circulation efficiency, exacerbating overheating and boiling when coolant levels are insufficient. If the antifreeze level was already low and regular checks were neglected, high-temperature driving makes it easier for the water to boil dry. These problems become more common as the vehicle ages, so it's recommended to have a technician thoroughly inspect the cooling components during every maintenance service.
