Taking Care of the Unexpected
229
If the High Coolant Temperature
Indicator Lights
Normally, the high coolant temperature indicator will only light
momentarily when you turn the ignition switch to ON (q).
High coolant temperature may be caused by restriction of air flow to
the radiator (such as mud caked on the radiator), extended idling, an
oil leak, a coolant leak, a low oil level, a low coolant level, or
extended operation under adverse conditions.
If the all segment of the coolant temperature gauge and high
coolant temperature indicator are on while you’re riding, don’t
ignore it. Pull safely to a stop. Stop the engine as soon as it’s safe to
do so, and let it cool.
NOTICE
Continuing to ride with high coolant temperature or 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.
• Check for any restriction of air flow to the radiator.
• If there’s no obvious problem, leave the engine on so the fan and
coolant circulating system can continue working. Monitor the
coolant temperature gauge and high coolant temperature
indicator. The indicator may turn off after a brief stop with no
load on the engine.
• Check the radiator fan.
If the fan is not working, turn the engine off. Open the fuse box
(page 232) 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 all segment of the coolant temperature gauge and
high coolant temperature indicator stays on, turn the engine off.
If the radiator fan is working, visually check the coolant level in
the reserve tank, located under the left front fender. It isn’t
necessary to touch the radiator system.
