Cooling system 125
Coolant, changing
IMPORTANT! To avoid damage to the engine, different kinds
of coolant or corrosion protection must not be mixed with
each other, see page 169.
Change coolant every 6000 hours or every fourth year.
Draining
1 Remove the expansion tank cap (A).
2 Bend down hose (B) by the radiator and press in the clamp on
the drain nipple so that coolant flows out.
3 Let down the belly plate. Connect the drain hose on the nipple
on the engine's lower left side (C).
NOTE! The cooling system is not protected against freezing
after draining. Pockets of water may remain in the system.
Take care of filters/oils/liquids in an environmentally safe way,
see page 97.
