- The problem
- On certain chassis built with lng engines, the nexgen lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.
- The risk
- This could cause ice buildup on the discharge side of the primary and secondary pressure system allowing the relief system to freeze and become blocked resulting in over pressurization of the lng tanks creating the risk of catastrophic tank rupture which could cause serious injury or death.
- The fix
- Dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began april 6, 2004. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact mack at 1-610-709-3337.
