Coolant replacement
Do not remove the radiator cap “1”, drain bolt and
hoses when the engine and radiator are hot. Scalding
hot fluid and steam may be blown out under pressure,
which could cause serious injury. When the engine
has cooled, place a thick towel over the radiator cap,
slowly rotate the cap counterclockwise to the detent.
This procedure allows any residual pressure to
escape. When the hissing sound has stopped, press
down on the cap while turning counterclockwise and
remove it.
– Remove the engine guard.
– Place the vehicle on a flat surface, in a vertical position by
placing a suitable stand under the engine.
– Remove the radiator cover “1” and the coolant drain plug
“2”, then drain the coolant completely by collecting it in the
container under the engine;
– Install a new washer on the drain plug “1” and install it in
its housing;
– Fill the engine and the radiator with “ETHYLENE GLYCOL
WITH ANTICORROSIVE FOR ALUMINIUM ENGINES”, up to
the level previously indicated.
Coolant quantity:
0,93 L (0.98 US qt, 0.82 Imp.qt)
Do not add additives or other substances and use
the products recommended in the “RECOMMENDED
PRODUCTS TABLE” section.
Do not mix more than one type of ethylene glycol
antifreeze containing corrosion inhibitors for
aluminum engine.
Do not use water containing impurities or oil.
4.2 COOLANT
Checking the coolant level
Do not remove the radiator cap “1”, drain bolt and
hoses when the engine and radiator are hot. Scalding
hot fluid and steam may be blown out under pressure,
which could cause serious injury. When the engine
has cooled, place a thick towel over the radiator cap,
slowly rotate the cap counterclockwise to the detent.
This procedure allows any residual pressure to
escape. When the hissing sound has stopped, press
down on the cap while turning counterclockwise and
remove it.
Hard water or salt water is harmful to the engine
parts. You may use distilled water, if you can’t get
soft water.
– Place the machine on a level place, and hold it in an upright
position;
– Remove the radiator cap “1” and check the coolant level.
Add coolant if the coolant level is low.
