What causes a chain driven water pump to fail?
Another reason why chain-driven water pumps fail is a worn or defective tensioner and guides. Most engines use oil pressure to actuate a tensioner that puts pressure on a guide. If the tensioner fails (typically due to a lack of oil changes), the chain will move around due to centrifugal force acting on the chain.
