Each and every water pump has a issue called weep hole. The internal mechanical seal of the pump seals the shaft in order to shield bearings by not allowing coolant to pass by way of bearing assembly. When the pump is new, a few seepage from the weep hole is standard due to the fact it requires around ten minutes for a mechanical seal to seat itself appropriately. The leakage occurs due to the contaminated coolant getting used. It is advisable to thoroughly clean the cooling system before installing the new pump and use the manufacturer advisable coolant.
