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.
WARNING!
Never drain or refill the cooling system when engine is hot.
Temperature of coolant varies between 40 °C - 90 °C.
WARNING!
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.
