he HY has an open cooling system. It is essential to check if the radiator cap is the right one ! The water pump can evacuate some cooling water through a small opening. New water pumps need approx. 500 km to 1000 km to get at 99,5 % leakproof. It is just normal to see some drops of water on the water pump!
