Use a mixture of 50 percent water and 50 percent
ethylene glycol antifreeze to fill the cooling system.
* 4BTA and 6BTA engines use a jacket-water
aftercooler. If a Charge Air Cooler is used, the
coolant capacity is the same as the naturally
aspirated or turbocharged only engines.
Never use water alone for coolant. Damage
from corrosion can be the result of using
water alone for coolant.
