Post Water Pump Diagnosis and Failures

Most quick water pump failures can be directly traced back to improper fan belt tension .

When running any engine sans fans belts to ascertain noises, be SURE to turn the heater FULL ON as hot spots can occur very quickly and spoil your day .

Glad it wasn't a vacuum pump failing .
