Water Pump: Testing and Inspection

A quick test to tell whether or not the pump is working is to see if the heater warms properly. A defective pump will not be able to circulate heated
coolant through the long heater hose.

NOTE:  It is normal for the water pump to weep a small amount of coolant from the weep hole (black stain on water pump body). Do not replace the
water pump if this condition exists. Replace the water pump if a heavy deposit or a steady flow of green/brown engine coolant is evident on water
pump body from the weep hole (shaft seal failure). Be sure to perform a thorough analysis before replacing water pump.
