Diesel water pumps are very delicate. They are also highly unpredictable; some can only go 50k miles before they fail whereas others are still able to run even after a long while.
That being said, there is nothing quite as frustrating as a diesel water pump failure while at work or driving. This could also lead to engine damage. As such, there factors that should be put into consideration in preventative water pump replacement.
When a water pump is leaking on a diesel engine, it should be replaced as soon as possible. This is in a bid to avoid costly engine problems. It is also important to note that most diesel engines don’t have a water pump maintenance interval.

This is because the water pump is expected to last the life of the engine under normal use. Unfortunately, that is rarely the case since many of these engines don’t see what’s considered “normal use”. Similarly, others see far more than the expected mileage on the engine.
Generally, service professionals have the tendency of waiting for things to break down before replacing them. However, equipment such as water pumps are labor intensive to replace. As such, the replacement is often held off until they start showing red flags. To avoid waiting until it’s too late, the water pump can be replaced when the vehicle is undergoing routine maintenance. This will not only save the hassle of replacing the pump, but will also ensure smooth running of the same.
On the other hand, when replacing a pump, be sure to select the best pump for the job. Some people opt to get re-manufactured units in order to keep costs at a minimal. However, there are companies that manufacture brand new diesel water pumps that go for more or less the same price as that of a manufactured unit.
