Inspecting the belt system is also important in this regard as it can be the cause of the premature failure of the shaft that can reduce the life of the pump. In fact, a leaking pump can lead to problems related to the tensioner and the belt. As a good preventive measure it is always suggested that when some problems develop regarding water pumps one can change the entire components like pump, drive components and belt at the same time.

The internal mechanical seal in the pump protects the bearing and prevents the coolant from entering the bearing assembly. Some seepage is natural in the initial days of a new pump. Continuation of weeping after the initial days is abnormal and represents some problems related to the pump. Contaminated coolant is the main reason for this problem. Flush out the system completely prior to  the installation of the new pump. Refill the pump with the suggested coolant.

This type of leakage is characterized by the bleed marks formed by seepage or drips. Defects in the installation of the pump can be the reason for the mounting surface leakage. This problem can be solved by re-installing the pump strictly following the specifications regarding the torque. Ascertain that the gasket/seals are perfectly positioned. Replace sealants, if any, cleaning the rim and replace them evenly. If it is not due to any wrong installation then it has to be replaced immediately.

Rust or corrosion happening to the water pumps can easily be distinguished by naked eye. One example is the problems caused by the impeller fin.

Causes: Contamination of the coolant, mixing of coolants of different varieties etc. can lead to rust or corrosion. Air bubbles caused by a damaged pressure cap can also accelerate the rusting process.

Solution: Replacing the water pump is the only solution once the corrosion has started. It will be very good if the cooling system is completely flushed before trying to install the brand new pump. Also assure that the system is refilled with exact coolant recommended by the manufacturer. Examine the pressure cap and if any defects are noticed replace it immediately.
