PACCAR issued a recall on the 335 and 340 models

On certain trucks, the right side stabilizing rod which spans the cooling module and the right frame rail bracket was inadvertently designed too close in proximity to the alternator positive electrical terminal post. In the event the protective rubber boot on the terminal post was removed or cracked and the engine mounts allowed the engine to rock, electrical arcing could occur, which may ignite a fire in the engine compartment. Correction: Dealers will replace the right radiator stabilizing rod and corresponding mounting bracket with updated versions.
