Defect
On certain chassis built with lng engines, the lng tank's primary and secondary relief valves could fail to open and relieve tank pressure.
Safety 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.
Remedy
Dealers will retrofit the lng tanks with a new primary relief valve pipe away tube and a new ventilated shroud. The recall began on may 14, 2004. Owners should contact fontaine at 1-800-544-8175.
Notes
Customers can also contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-DOT (1-888-327-4236).
