S 07 MAINTENANCE
• Install the new impeller with a rotary motion in
the direction it will rotate.
• Lubricate the seal with glycerin. Install the O-ring/
gasket and cover.
CAUTION!
Do not use petroleum-based products to lubricate the in-
side of the pump. Use only glycerin. Other products can
damage the impeller, which will damage the pump and
cause motor failure. Do not operate the impeller without
water or lubricant, as this may cause motor failure or fire.
COOLANT REPLACEMENT
DANGER!
Do not remove the pressure cap from the heat exchanger
when the engine is hot. Then loosen the cap slightly to
release excess pressure before removing it completely.
ENVIRONMENT!
Use a suitable container. Used oil must be disposed of in
accordance with national and international laws and reg-
ulations.
Coolant draining

2. To drain the coolant, open the drain valve (1) on the
engine block under the oil pressure sensor.
3. Remove the expansion tank cap (2) and the exhaust
manifold cap (3).
4. Unscrew the clamps (4) and remove the hoses (5) and
