MAINTENANCE
COOLING SYSTEM
FOR SAFETY: When servicing machine, avoid
contact with hot engine coolant. Do not remove
cap from radiator when engine is hot. Allow
engine to cool.
Check the radiator coolant level in the radiator site
glass daily. The coolant level must be visible in the
radiator site glass. Use distilled water mixed with
a permanent-type, ethylene glycol antifreeze to a
−
34° C (
−
30° F) rating. Add coolant to the radiator.
Add one pint of conditioner to each coolant
change.
Check the radiator hoses and clamps every 100
hours of operation. Tighten loose clamps. Replace
the hoses and clamps if the hoses are cracked,
hardened, or swollen.
Check the radiator core exterior, hydraulic cooler,
and turbo cooler
fi
ns for debris daily. Blow or rinse
dust and debris collected on the radiator from the
inside face (closest to the engine fan) of the grill
and radiator
fi
ns and out to the exterior of the
machine. Be careful to not bend the cooling
fi
ns
when cleaning. Clean thoroughly to prevent the
fi
ns from becoming encrusted with dust. Clean the
radiator and cooler only after they have cooled to
avoid cracking.
ATTENTION! Do not wash the fuel injection
pump or turbocharger when the engine is
running or warm. This could damage these
components.
Flush the radiator and the cooling system every
1600 hours of operation, using a dependable
cleaning compound. Add one pint of conditioner
(TENNANT part no. 770172) to each coolant
change.
