Level Check; Top-Up - APRILIA RS4 125 Service Station Manual

RS4 125
DO NOT USE THE SCOOTER IF THE COOLANT LEVEL IS BELOW THE MINIMUM MARK.
WHEN CARRYING OUT MAINTENANCE OPERATIONS, IT IS ADVISABLE TO WEAR LATEX
GLOVES.
TAKE YOUR SCOOTER TO AN OFFICIAL aprilia DEALER TO HAVE COOLANT CHANGED.
Coolant solution is 50% water and 50% antifreeze fluid.
This is the ideal mixture for most operating temperatures and provides good corrosion protection.
It is advisable to use the same mixture even in hot weather as this minimises loss due to evaporation
and the need of frequent top-ups.
Thus, less evaporated water means fewer mineral salt deposits in the radiators, which helps preserve
the efficiency of the cooling system.
When the external temperature drops below zero degrees centigrade, check the cooling system fre-
quently and add more antifreeze solution if needed (up to 60% max.).
Use distilled water in the coolant mixture to avoid damaging the engine.
DO NOT REMOVE THE EXPANSION TANK PLUG WHEN THE ENGINE IS HOT, SINCE COOLANT
IS UNDER PRESSURE AND VERY HOT.
CAUTION
WAIT FOR THE ENGINE TO COOL DOWN BEFORE CHECKING OR TOPPING-UP COOLANT
LEVEL.
