The engine of Ruifeng car boils.

The problem of high water temperature depends on the specific situation: we must start with a simple inspection: the simplest one, such as the poor sealing of the lid of the expansion kettle, leads to a large amount of evaporation of coolant after the water temperature comes up, and the water temperature is naturally high. Then look at the cooling system, see if the fan works normally, see if the water tank is blocked, and see if the water circulation is blocked. Is the thermostat working properly? Then check whether the water pump is broken. Just accelerate in place and see if the water temperature will come down. If everything is all right, it is necessary to doubt whether it is flushing the cylinder bed, see if there is water in the engine oil, and see if there is bubbling in the kettle when accelerating.
