If Your Engine Overheats
0 Check the radiator fan.
If the fan is not working, turn the
engine off. Open the fuse box (page
156 ) and check the radiator fan fuse.
If the fuse is blown, replace it with the
proper (same rating) spare fuse. Start
the engine. If the needle climbs to the
red zone and stays there, turn the engine
off.
If the radiator fan is working, visually
check the coolant level in the reserve
tank, located behind the frame (page
81 ). It isn't necessary to touch the
radiator system.
0 If the reserve tank is low or empty, don't
ride without adding coolant (page 81 ).
After adding coolant, turn the engine on
and check the temperature gauge.
If the needle doesn't drop, do not ride.
The engine needs repair. Transport your
motorcycle to a Honda dealer (page
134 ).
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 gauge frequently.
If there's a mild leak, you can ride for
awhile, carefully watching the gauge. Be
prepared to stop and add more coolant or
water. If the leak is bad, transport your
motorcycle to a Honda dealer (page 134 ).
