Standard Life Coolant (also known as Conventional) Drain Intervals:
Engine Series SLC
Series 60, 50, 40
300,000 miles (482,800 km) or 2 years
MBE4000, MBE900
DD5, DD8, DD13, DD15, DD16
Supplemental Coolant Additives (SCA)
Supplemental Coolant Additive (SCA) Solutions- for Ethylene or
Propylene Glycol-based Antifreeze Coolants
The coolant must be maintained with the proper concentration of corrosion
inhibitors. As the concentration of inhibitors deplete, additional SCA must be
added to the coolant as indicated by a nitrite concentration of 900 PPM, or less. If
the nitrite concentration is greater than 900 PPM, do not add additional SCA. If the
nitrite concentration is above 3200 PPM, the system is over-inhibited. The system
should be partially drained and filled with a 50/50 mix of water and EG or PG.
Supplemental Coolant Additive (SCA) Solutions - for Water-based
Coolants (Legacy Engines Only)
In warm climates where freeze protection is not required, water only with corrosion
inhibitors is approved for use. Water-only systems need to be treated with the
proper dosage of corrosion inhibitors. Detroit™ approved conventional SCA or
OAT corrosion inhibitors must be added to the water to provide required corrosion
and cavitation erosion protection.
Need-Release Coolant Filters (STANDARD LIFE COOLANT ONLY
1
)
Need-Release coolant filters are available for Series 50, Series 60 and pre-2016 DD
series engines. Membranes in the filters release SCAs before the coolant
approaches a corrosive condition, protecting the engine from corrosion. The need-
release elements release the SCA charge as needed, as opposed to the maintenance
SCA elements, which instantaneously release the SCA charge. Need-release
coolant filter elements should be replaced after one year or 100,000 miles (160,000
km), or 3,000 operating hours, whichever comes first.
1. Need-Release filters are not to be used with ELC type coolants. Such use will
cause serious damage to the engine.
