CAUTION: All hoses and fittings of the cooling
system have calibrated inside diameters to as-
sure proper cooling of the engine. Always re-
place using appropriate Bombardier part num-
ber.
CAUTION: Never modify cooling system ar-
rangement, otherwise serious engine damage
could occur.
Refer to exploded view for coolant flow in circuit.
