Check oil level. Dipstick is on top of engine between branches of intake manifold (Figure 2-8). Oil level should be
between top and bottom of rough hatchmark area of the stick. Fill with oil, when necessary, through the oil filler
cap on top of the engine. Use diesel lubricating oil CD (MIL-L2104), SAE 20W30, above 50°F and oil CD, SAE
10W, below 50F.
g.
Check coolant level in heat exchanger by opening cap at front of engine. If necessary, fill to upper edge of splash
plate on thermostat housing. Coolant must be either a 50-50 mixture of fresh, clean water and corrosion-
protective antifreeze or fresh, clean water with a corrosion-protective additive. If coolant level is very low, check
again after engine has started and is idling. If necessary, add additional coolant to bring it to upper edge of
