Coolant Terms
Ethylene Glycol containing a corrosion inhibitor package and which
meets an appropriate heavy-duty specification (i.e., TMC RP-329
Type A or ASTM Standard D6210 Type A for ethylene glycol).
The fluid mixture circulating in the engine cooling system, typically a
mixture of 50% water and 50% antifreeze.
Precipitated sludge or deposit formation on cooling system
components.
Contains all the necessary inhibitors to protect a diesel engine, and
does not, therefore, require a pre-charge of Supplemental Coolant
Additive before its first use.
The coolant that is used in a new or rebuilt engine, or any time the
cooling system is emptied and then refilled with coolant.
Organic Acid Technology. An inhibitor system based on organic acid
inhibitors instead of traditional North American inhibitor formulations.
Supplemental Coolant Additive. Supplemental Coolant Additives are
used in a preventive maintenance program to prevent corrosion,
cavitation, and the formation of deposits.
