    How to Procedures • Soluble Oils: Soluble oil additives are not approved for use in Detroit™ engine cooling systems. A small amount of oil adversely affects heat transfer. For example, a 1.25% concentration of soluble oil increases the fire deck temperature 6%.

  • Page 102 To best measure the quality of anti-freeze coolant, a check of the freeze point (glycol concentration), by refractometer, should be performed at each service interval to ensure anti-freeze levels are within specification. Detroit™ requires a freeze point between -31°C and -42°C (-24°F and -44°F) to guarantee optimal engine protection.

    The pre-mixed antifreeze is ready to use, while the concentrated coolant must be mixed with water prior to use. All fully formulated coolants used must also meet Detroit 93K217 specification. NOTE: Fully formulated antifreeze does not require a dosage of Supplemental Coolant Additive (SCA) at initial use.

An antifreeze concentration below 40% (40% antifreeze, 60% water) offers too little freeze and/or corrosion protection and is not recommended. WATER REQUIREMENTS Distilled or de-ionized water, which eliminates the adverse effects of minerals in tap water, is preferred.
