Cleaning Radiator and Screen
To prevent engine overheating, keep the screen and
radiator clean. Normally, check the screen and
radiator daily and, if necessary, clean any debris from
these parts. However, it will be necessary to check and
clean the screen and radiator frequently in extremely
dusty and dirty conditions.
Note: If the engine shuts off due to overheating, first
check the radiator and screen for an excessive buildup
of debris.

Changing Coolant in the Cooling
System
Capacity of cooling system is approximately 6 quarts
1
(5.7 L). The cooling system must be filled with a
50/50 solution of water and permanent ethylene glycol
anti-freeze. Every two years, drain the coolant from
the radiator by opening the drain cock (Fig. 28). After
coolant has drained, flush the entire system and refill
it with a 50/50 solution of water and anti-freeze.

Repeat the previous steps on the remaining
nozzles.
Remove the screen.
Working from the fan side of the radiator, either
spray the radiator with a water hose or blow with
compressed air.
After the radiator is thoroughly cleaned, clean
out debris that may have collected in the channel
at the radiator base.
Clean and install the screen.
