Engine overheating

WARNING

EWA10400

Do not remove the radiator cap when the engine and radiator are hot. Scalding hot fluid and steam may be
blown out under pressure, which could cause serious injury. Be sure to wait until the engine has cooled.

After removing the radiator cap retaining bolt, place a thick rag, like a towel, over the radiator cap, and then
slowly rotate the cap counterclockwise to the detent to allow any residual pressure to escape. When the hissing
sound has stopped, press down on the cap while turning it counterclockwise, and then remove the cap.

NOTE:

If coolant is not available, tap water can be temporarily used instead, provided that it is changed to the recommended coolant
as soon as possible.

Wait until the 
engine has cooled.

Check the coolant level in the 
reservoir and radiator.

The coolant level 
is OK.

The coolant level is low.
Check the cooling system
for leakage.

Have a Yamaha dealer check
and repair the cooling system.

Add coolant. (See NOTE.)

Start the engine. If the engine overheats again, 

have a 

Yamaha dealer check and repair the cooling system.

There is
leakage.

There is 
no leakage.
