A bad water pump can be a lead to for concern to numerous automobile owners and so in today's article, we are going to look at the indicators of a bad water pump. 1Check for shaft seal failure by carefully inspecting the water pump weep hole When a water pump is new. some seepage is standard in the initial hours of operation as the seal seats Other than that, any leakage that occurs is due to seal failure and the pump requirements replacement. There might be tell tale trails of rust calcium and coolant deposits on the water pump housing with the weep hole as the origin.
Water pumps are not good displacement pumps. The water pump is a centrifugal pump that can move a huge volume of coolant without having increasing the stress of the coolant. The pump pulls coolant in at the center of the impeller. Centrifugal force throws the coolant outward so that it is discharged at the impeller ideas.
Leaks: One particular of the early signs is a coolant leak from the water pump. The water pump has a weep (bleed) hole in the lower portion see the photo. A tiny quantity of dry coolant residue about the weep hole is regular, but coolant leaking from the weep hole is a sign that the pump is on its way.
