MAINTENANCE
It is extremely important that when antifreeze
is used, that it be mixed with water in a
separate container before adding. NEVER
add straight antifreeze to the radiator.
Recommended mix is 50/50 lowtox
(propylene glycol) phosphate-free antifreeze
with tap water. DO NOT mix in ethylene
glycol. Refer to engine operatorís manual.
The radiator for this cooling system is
provided with two drain valves; one at each
end of the lower tank. When draining the
system, it is necessary to open both these
valves to drain the radiator completely.
Add coolant to the bottom of the fill cap again.
Install radiator pressure cap. Add coolant to
the proper line on the over flow tank between
FULL and LOW.
When refilling the system, it is important that
all trapped air be purged. The following
procedure will help to insure this:
1. Make sure the engine is level. Fill the
overflow reservoir up to the MAX mark
with coolant mixture.
2. Slowly fill the radiator to the bottom of the
filler neck with coolant mixture.
3. With radiator cap off, start the engine
and let it warm up (no-load). Then, if
necessary, add more coolant mixture to
bring the level back up to the bottom of
the filler neck.
4. Reinstall the radiator cap and run the
engine a short time with the system
sealed while watching the temperature
gauge. If the temperature gauge goes
past 230 degrees and does not drop
back to approximately 190 degrees,
indicating the thermostat has opened,
allow the engine to cool down, check for
leaks and repeat the procedure.
This is a sealed system. If it becomes
necessary to add coolant mixture at a later
date, check for leaks and if the overflow
reservoir has not been drained completely,
add coolant mixture to the reservoir only. This
will help prevent air pockets in the radiator top
tank and lessen the chance of introducing
contaminates to the system.
