Cooling system antifreeze protection
and coolant level, checking


CAUTION!

Part numbers are for reference only. Always
check with your Parts Dept. for the latest
parts information.
Coolant antifreeze, Part No. G 11 prevents frost
and corrosion damage, lime deposits, and also
raises the boiling temperature. Cooling system
must be filled year round with antifreeze and
corrosion protection agent.
Concentration of coolant must not be reduced by
adding wa ter, even during summer or in warmer
climates. Coolant antifreeze percentage must be
at least 40%.
Because of its high boiling point, coolant
contributes to safe operation at high engine load,
especially in warmer climates.

- Check concentration of coolant antifreeze.

Antifreeze protection must be approximately
-25 C (-13 F) for US and -35 C (-31 F)
for Canada.

For antifreeze protection down to

approximately -40 C (-40 F), the
percentage of G 11 may be increased up to
60%. The percentage of G 11 must not
exceed 60%, higher amounts will decrease
frost protection and cooling capacity.

If antifreeze protection is not adequate, drain
off quantity indicated in following table and
top off with coolant antifreeze G 11.
