Check the radiator fans.
If either or both are not working, turn
the engine off. Open the fuse box
(page 216 ) and check the radiator fan
fuses. If the fuse is blown, replace it
with the proper (same rating) spare fuse.
Start the engine. If the warning
indicator and the high coolant
temperature indicator go on, turn the
engine off.
If the radiator fans are working,
visually check the coolant level in the
reserve tank, located behind the rear
brake fluid reservoir. It isn't necessary
to touch the radiator system.
The operation temperature of each
cooling f an is dif f erent. Theref ore, it is
normal when only one of the f ans operate.
If Your Engine Overheats
If the reserve tank is low or empty, don't
ride without adding coolant (page
After adding coolant, turn the engine on
and check the temperature meter.
If the temperature doesn't drop, do not
ride. The engine needs repair. Transport
your motorcycle to a Honda dealer
(page 187 ).
If the temperature drops to normal,
check the coolant level. If it has gone
down, add more coolant.
If you are able to resume riding, continue
to monitor the meter frequently.
If there's a mild leak, you can ride for
awhile, carefully watching the meter. Be
prepared to stop and add more coolant or
water. If the leak is bad, transport your
motorcycle to a Honda dealer (page
