RADIATOR CAP/SYSTEM PRESSURE
INSPECTION
Remove the radiator cap.
Wet the sealing surfaces of the cap, then install the
cap onto tester.
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. It must hold
the specified pressure for at least 6 seconds.
RADIATOR CAP RELIEF PRESSURE:
108 – 137 kPa (1.1 – 1.4 kgf/cm

COOLANT REPLACEMENT
PREPARATION
Using coolant with silicate corrosion inhibitors may
cause premature wear of water pump seals or
blockage of radiator passages. Using tap water may
cause engine damage.
• The effectiveness of coolant decreases with the
accumulation of rust or if 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 rec-
ommended antifreeze.
RECOMMENDED ANTIFREEZE:
Pro Honda HP Coolant or an equivalent high
quality ethylene glycol antifreeze containing
silicate-free corrosion inhibitors
RECOMMENDED MIXTURE:
