Fill (010-001-028)
CAUTION
During filling, air must be vented from the engine cool-
ing passages. Open the engine vent petcock. Make sure
to open the petcock on the aftercooler, for aftercooled
engines. The system must be filled slowly to prevent air
locks. Wait 2 to 3 minutes to allow air to be vented, then
add coolant to bring the level to the bottom of the
radiator filler neck. Failure to do so will cause entrap-
ment of air in cooling system and will cause engine to
overheat.
Fill the coolant system with a premixture of 50-percent
water and 50-percent ethylene-glycol-type antifreeze.
