    Is the water pump working properly? Do you know the last time the impeller was replaced? Is it possible it may be running too hot? I’m sure it isn’t running on the driveway with very much throttole. If it is on a garden hose, the hose pressure will mask a poorly functioning water pump. Just some thoughts.
