Question

Quizplus · Accepted Answer

If the impeller blades are worn or slipping on the shaft, the water pump will not be able to provide the proper amount of coolant flow through the system. The other options (coolant leaking from the weep hole, bearing failure causing a loose shaft, and noisy bearing) may indicate a problem with the water pump, but may not necessarily result in a failure to provide coolant flow.
