Water pump is a part of the coolant circuit. Usually the cause of the water pump failure is its wear. Permanent mechanical stress can result in leaks. Moreover, the pump can completely fail. If there appears coolant under the vehicle, this indicates a leak in the coolant circuit. When searching for a leak, it is necessary carefully to examine the water pump. A water pump failure can destroy your entire engine.
Water pumps can last a fairly long time on vehicles with properly maintained coolant systems. Changing your car or truck’s coolant in regularly scheduled intervals will go a long way in preventing failure of any coolant system components. An early sign would be what is known as the “weep hole drip,” which refers to a small amount of coolant leaking from the water pump onto the ground. Other possible auto water pump failures can be due to a cracked housing, broken impeller or main shaft.
