Plastic coolant union on radiator hose going from the coolant expansion tank to the electric auxiliary coolant pump catastrophically failed when I was changing the lh driver side front headlight bulb. I was leaning over the front of the vehicle with my head down to view the back side of the headlamp to remove the bulb, the plastic coolant union broke at this exact time shooting hot engine coolant all over my face. I've suffered 2nd and 3rd degree burns to my face, lips, neck and chest as a result. The vehicle engine was on, at idle speed, vehicle stationary in driveway.
