Check the water pump for leaks and excessive play or looseness of the shaft and bearings. If there is evidence of excessive play when the fan blades are manually moved up and down, it shows that the bearings are rough. If water leaks from the hole located on the pump body, it indicates defective seal necessitating overhaul of the pump.
