Temperature Indicator Lights
Normally, the high oil/coolant temperature indicator will only light
momentarily when you turn the ignition ON (q). Occasionally, it may
flicker at or near idling speed.
High oil/coolant temperature may be caused by restriction of air flow
to the radiator (such as mud caked on the radiator or oil cooler),
extended idling, an oil leak, a coolant leak, a low oil level, a low
coolant level, or extended operation under adverse conditions.
If the indicator comes 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 low oil pressure 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 or oil cooler.
• If there's no obvious problem, leave the engine on so the fan and
coolant circulating system can continue working. Monitor the
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 199) 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 high coolant temperature indicator comes on and
stays on, turn the engine off.
If the radiator fan is working, visually check the coolant level in
the reserve tank, located under the rear fender. It isn't necessary
to touch the radiator system.
