OPERATOR’S MANUAL
COOLING SYSTEM
LIQUID COOLED ENGINES
Always replenish the system with the solution (50 % antifreeze, 50
% water). Pure antifreeze without water freezes.
Always use ethylene-glycol antifreeze containing corrosion
inhibitors specially recommended for aluminium engines.
The engine cooling system should be drained and refilled with a
new coolant mixture before each storage period.
NOTE: Cooling system is pressurised.
NOTE: Never drain or refill the cooling system when engine is hot.
Temperature of coolant varies between 40 °C - 90 °C.
CAUTION! In case temperature of coolant is over 100 °C, reduce
speed, drive on loose snow for better cooling, or stop the engine
immediately.
Draining the cooling system
Siphon the coolant mixture from the cooling system using a primer
pump, a length of plastic hose and steel tubing inserted as deep as
possible into the lower hose of the engine.
Remove the bleed screw on the cylinder head, water pump house
and radiators connecting hose and lift the rear of the vehicle to get
engine and radiators totally empty.
Refill the cooling system
· Open the bleed screws.
· Refill the cooling system slowly until coolant runs out from
bleed screws. Make sure, that air is totally removed from
the system.
· Tighten bleed screws.
