    5.3.1 Fully Formulated Antifreeze Antifreeze approved for use in the MBE 4000 engine is a mixture of glycol compound (ethylene glycol), and corrosion inhibitors. Antifreeze containing glycol compounds and corrosion inhibitors is known as fully-formulated antifreeze.
  • Page 396 The concentrations of some inhibitors will gradually deplete during normal engine operation. SCAs replenish the protection for cooling system components. The coolant must be maintained with the proper concentration of SCA. Detroit Diesel Power Cool maintenance SCAs are recommended. All information subject to change without notice.
  • Page 397 Recycled Antifreeze Recycled antifreeze that complies with TMC RP-329 Type “A” (for ethylene glycol) is approved for use in MBE 4000 engines. The antifreeze must be recycled by distillation, reverse osmosis, or ion exchange. Other recycled antifreeze, especially any antifreeze recycled by means of filtration processes, is not approved.
  • Page 398 This can cause deposits or dropout in the cooling system. The following types of corrosion inhibitors are approved for use in MBE 4000 engines: Supplemental Coolant Additives (SCAs) Nitrated Organic Acid Technology (NOAT) Inhibitors Corrosion inhibitors are very important in maintaining engine life. All corrosion inhibitors protect against corrosion caused by acid, and cavitation of wet cylinder liners.
  • Page 399 5.3.6 Non-Approved Coolants The following types of coolant are not approved for use in MBE 4000 engines: Antifreeze or coolant containing phosphate can cause dropout, overheating, and damage to coolant pump seals. Automotive coolants offer no protection against liner pitting, and generally contain high levels of phosphate and silicate.
