The defect
ON CERTAIN TRUCKS EQUIPPED WITH LIQUID NATURAL GAS (LNG) STYLE TANKS, NEITHER THE PRIMARY NOR THE SECONDARY RELIEF VALVES HAVE OPENED TO RELIEVE TANK PRESSURE UNDER CERTAIN CONDITIONS. SPECIFICALLY, THE INTRODUCTION OF WATER INTO THE DISCHARGE SIDE OF BOTH OF THESE VALVES SIMULTANEOUSLY AND SUBSEQUENT FREEZING IN SERVICE CAN RENDER THE VALVES TEMPORARILY INOPERATIVE.
The risk
THIS CONDITION CREATES THE RISK OF TANK OVER-PRESSURIZATION AND A POTENTIAL TANK RUPTURE, POSSIBLY RESULTING IN SERIOUS INJURY OR DEATH.
The remedy
DEALERS WILL RETROFIT THE LNG TANKS ON THE VEHICLES WITH A NEW PRIMARY RELIEF VALVE PIPE AWAY TUBE AND A NEW VENTILATED SHROUD COVER; ENSURE THE RELIEF VALVES ARE MOISTURE FREE AND ENSURE THAT THE RED COVER IS PRESENTLY IN PLACE ON THE SECONDARY RELIEF VALVE. THE RECALL BEGAN OCTOBER 14, 2004. OWNERS MAY CONTACT FREIGHTLINER AT 1-800-547-0712.
