    Diesel Exhaust Fluid Availability Diesel Exhaust Fluid (DEF) is available in various container sizes at authorized Detroit™ service outlets, truck stops and many truck service outlets. DEF is available in container sizes as small as 2.5 gallons for convenient, in-vehicle storage in case of emergency use.

  • Page 68: How To Select Coolants

    Concentrated coolants should be mixed at 50% (50% coolant/50% water). All ELCs used must also meet DFS 93K217 specification. Detroit™ requires that these types of coolants be free of nitrite and phosphate. Detroit™ has found that ELC's containing nitrite may lead to a breakdown of the coolant and subsequent damage to the cooling system.
  • Page 69 These coolants require interval testing to maintain inhibitor concentration. SLC antifreeze coolants are commercially available from Detroit™ service outlets and other manufacturers as either concentrated or as pre-mixed coolant. Concentrated coolants should be mixed at 50% (50% coolant/50% water). All fully formulated coolants used must also meet DFS 93K217 specification.
  • Page 70 Coolants Not Permitted The following coolants are not to be used in Detroit™ Gen 5 Heavy Duty engines : • Automotive/Passenger car-type coolants must not be used because they offer no liner pitting protection. Also, these types of coolants generally contain high levels of phosphates and silicates.

  • Page 71: How To Select Fuel

    Cooling systems operated with a chromate-inhibited coolant must be chemically cleaned with specially formulate cleaning agents available through authorized Detroit™ service outlets. Only use Detroit™ approved cleaning agents. • Phosphate Inhibitors: Phosphate has tendency to form deposits on surfaces transferring high heat which ultimately affect cooling capabilities.

  • Page 72: How To Drain The Fuel Coalescer

    The use of supplemental fuel additives does not necessarily void the engine warranty. However, warranty and repair expenses which are determined, by Detroit™ or its representative, to have resulted from a fuel additive will not be covered by Detroit™ warranty.
