Pressurize the radiator cap using the tester.
Replace the radiator cap
if
it
does not hold pressure , or
if relief pressure is too high or too low. II must hold the
specified pressure for at least 6 seconds.

Usmg coolant with silicate corrosion inhibitors may
cause premature wear
o(
water pump seals or blockage
of radiator passages. USing lap waler may cause
engine damage.
NOTE
The effectiveness of coolant decreases With the
accumulation of rust or
jf
there is a change in the
mixing proportion dUring usage. Therefore. for best
performance change the coolant regularly as
specified in the maintenance schedule.
Mix only distilled, low mineral water with the
recommended antifreeze .
RECOMMENDED ANTIFREEZE :
Pro Honda HP Coolant or an equivalent high
quality ethylene glycol antifreeze containing slli-
cate·free corrosion Inhibitors
RECOMMENDED MIXTURE :
1:1 (mixture with distilled water)
