Filling Sequence
To prevent the inconvenience of having the generator
set shut down or become damaged due to overheating,
keep the cooling air inlets to the system clean and
unobstructed at all times. Inspect the exterior of the
radiator for obstructions; remove all dirt and foreign
material with a soft brush or cloth (to avoid damaging
radiatorfins).Checkallhosesandconnectionsforleaks
and replace any hoses that are cracked, frayed, or feel
spongy. When coolant level checks are made, check
condition of the radiator cap rubber seal; replace if
cracked or deteriorating. Remove dirt and other debris
from the radiator cap and filler neck.
Coolant capacity for the 10CCOZ-Mobile inline radiator
modelis 5.1 qts.(4.8 L). Drainpetcocks are providedon
thebottomtankofthe radiator and anotherintheengine
block to drain the system. When draining the coolant,
remove the radiator cap and open the block drain
locatedneartheflywheelhousing andtheradiatordrain;
this will allow the entire system to drain and prevent air
pockets from forming and restricting coolant passagein
the block. To refill the cooling system, close both drains
and fill the radiator to the proper level with the
recommended coolant mixture. See Figure 3-9 for
coolant fill location. Replace the radiator cap and
operate the engine until the thermostat opens and the
radiator upper hose becomes hot. Stop the engine and
allowto cool. Addcoolant tothe radiatorto raisecoolant
level just below the overflow tube on the filler neck.
Replace the radiator cap.
A coolant solution of 50% ethylene glycol and 50%
clean, softened water is required to inhibit corrosion,
prevent freezing to --34_F (--37_C), and to improve
cooling. The antifreeze should contain a rust inhibitor
and be changed every two years. Do not use alcohol or
methanolantifreezeormixthemwiththecoolant. Donot
add coolant to an engine that has overheated until the
engine has cooled. Adding coolant to an extremely hot
engine can cause a cracked block or cylinder head.
Check coolant level frequently and add antifreeze
solution as needed to maintain level just below the
overflow tube and at the min. level in the overflow tank
when cold (max. when hot).
NOTE
Special attention should be given when checking for
propercoolantlevel.After aradiatorhasbeendrained,it
normally requires some time before complete refill of all
air cavities take place.
