NOTE: ELC 50/50 Premix is the standard factory fill for the
cooling system. ELC 50/50 Premix is used to replenish coolant
loss and ensure that glycol/water concentrations stay in balance.
If a customer wishes to use a conventional (non OAT ELC)
coolant, it should minimally meet ASTM D6210, Standard
Specification for fully - Formulated Glycol Base Engine Coolant
for Heavy Duty Engines. Coolant service intervals are more
frequent with conventional coolants.
4. Add the same volume of Extender to the cooling system.
5. Install and tighten the coolant tank cap until the plastic cap
clicks or the metal cap runs up against the detent.
