Radiator Cap/System Pressure Inspection; Coolant Replacement Preparation - Honda MUV700 big red Service Manual

RADIATOR CAP/SYSTEM PRESSURE
INSPECTION
Remove the radiator cap !page 7-4),
Wet the sealing surfaces of the cap, then install the
cap onto tester.
TOOLS:
Cooling system pressure tester
Cooling system adaptor
SVTS4AH
OTCJ33984A
Pressurize the radiator cap using the tester.
Replace the radiator cap jf it does nOI 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:
93 - 123 kPa (0.95 - 1.25 kgf/c:m', 14 - 18 psi)
Pressure test the radiator, engine and hoses, and
check for leaks.

COOLANT REPLACEMENT
PREPARATION
I
NOTICE
I
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.
NOTE
• 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 co ntaining
silicate-free corrosion inhibitors
RECOMMENDED MIXTURE:
1:1 (distilled weter end recommended antifreeze)
