Engine Radiator Maintenance
DAILY/8 HOURS
COOLANT LEVEL
Check the engine radiator coolant level and add coolant if necessary. The coolant should
be visible in the sight gage near the top of the radiator tank. A solution of 50% ethylene
glycol by volume is the recommended year-round coolant. Replenish the corrosion inhibitor
if necessary. Refer to the “Operation Guide” supplied with the engine, or the nearest Engine
manufacturer’s service center for guidance in selecting the proper conditioner for the
cooling system.
In climates where freezing does not occur, use a solution of clean water with a corrosion
inhibitor for optimum cooling.
MONTHLY/160 HOURS
RADIATOR EXTERIOR
Clean any foreign matter from the radiator cooling fins and through-core cooling passages
by directing compressed air and flushing water over the entire area of the core in the
reverse direction of normal air flow.
QUARTERLY
CORROSION INHIBITOR
Replenish the cooling system corrosion inhibitor every 500 hours of operation.
Never use a chromate base corrosion inhibitor when the coolant contains
ethylene glycol. Use only non-chromate base inhibitors. Chromate base inhibitors
reacting with ethylene glycol can produce chromium hydroxide, commonly
known as “green slime”. This substance reduces the heat transfer rate and can
cause serious engine overheating.
SEMI ANNUALLY
COOLING SYSTEM
Clean the cooling system at 2,000 hours or annually whichever comes first. Use a radiator
cleaning compound, following the instructions on the container. Flush the system with fresh
water and refill with an ethylene glycol solution of 50% by volume.
