12.3) Requirements on the cooling system
■ ATTENTION: All components of the cooling system have to be secured suitably.
▲ WARNING: The size and layout of the cooling system must be designed to keep
the operating temperatures within the specified limits.
To minimize flow resistance employ radiator with low flow resistance
and parallel flow as realized on the original BOMBARDIER-ROTAX
radiator and use short hoses and pipelines.
Coolant hoses:
➪ temperature durability: min. 125°C (257° F)
➪ pressure durability: min. 5 bar (73 p.s.i.)
➪ nom. inside dia : 25 mm (1")
➪ bending radius: min. 175 mm (7")
➪ material: Suitable for 100 % Glycol and antifreeze agents.
■ ATTENTION: Pay attention to ozone stability!
◆ NOTE: If installation require longer distances use aluminium pipes (25 mm
(1") inside dia.) instead of hoses.
12.4) Size and position of connections
