162 Taking Care of the Unexpected
If Your Engine Overheats
Normally, the segments on your coolant temperature gauge begin to move
above the C (cold) mark and remain within the section between C (cold) and H
(hot) marks. Hot weather may cause the number of segments the gauge displays
to climb faster than normal. So will temporary stress such as climbing a hill. If
you’re stuck in stop-and-go traffic, the number of segments may climb some,
but the radiator fan is designed to prevent overheating. Be aware of these
variations as you monitor the gauge.
If the number of segments climbs toward H (hot)
mark for
no apparent reason or
the segment H flashes, pull safely to the side of the road. If possible, park in a
shady area.
Continuing to ride with an overheated engine can cause serious engine damage.
• A steaming engine indicates a coolant leak. Shut the engine off and wait until
the steaming stops. Look for a leak, but don’t touch the engine or radiator
system. Let everything cool off first.
• If there’s no obvious problem, leave the engine on so the fan and coolant
circulating system can continue working. Monitor the temperature gauge.
The number of segments the gauge displays may drop after a brief stop with
no load on the engine.
• Check the radiator fans.
If the fans are not working, turn the engine off. Open the fuse box (page 165)
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 number of segments climbs
toward H (hot) mark and the segment H flashes, turn the engine off.
If the radiator fans are working, visually check the coolant level in the reserve
tank, located below the left maintenance lid. It isn’t necessary to touch the
radiator system.
