There are many things that can prevent a diesel truck from starting in the winter, from a weak battery to air or water in the fuel lines. And no matter the weather, running out of Diesel Exhaust Fluid (DEF) will also stop the truck cold. If the engine is shut off when the DEF tank is empty, many systems won’t let it restart until DEF is replenished. This isn’t engine failure, but a deliberate design to protect emissions system integrity. When refilling a DEF tank that has run empty, add Rislone DEF Crystal Clean® to dissolve any white crystal deposits that may have formed. Learn more at Rislone.com/diesel-defense.
