Haval h6 antifreeze leaked out for half a year.

It is not normal for Haval h6 antifreeze to leak after half a year.

Check the positive crankcase ventilation valve for wear. High consumption of antifreeze. Has the vehicle overheated before? Check the spark plug mounting hole for antifreeze leakage.

Check all the pipe heads on the engine for leakage caused by oxidation! Check the heater tank.
