Ford diesel engines utilise a mechanical water pump to circulate engine coolant. Over time the seals inside the water pump can wear out and cause the pump to leak, subjecting the engine to overheating. A home mechanic can remove the water pump from a Ford diesel engine, but it may take some time due to the need to remove some other parts.
