Platform recipes (4)
- Common-rail injector replacement for 2003-2007 trucks (mode fm-c59-cr-injector-wear): worn nozzles and copper-seal blow-by ('chuffing')
- Fuel supply health across all three 5.9 generations (mode fm-c59-lift-pump-failure): every electric frame pump on these trucks is a consumable, and 2005+ moved it in-tank
- Killer Dowel Pin (KDP) prevention for the 12v P-pump engines (mode fm-c59-kdp-dowel-pin): the dowel pin that locates the front cover can back out and drop into the gear case
- VP44 death cascade repair for 1998.5-2002 24v trucks (mode fm-c59-vp44-failure)
