Cleaning the heat exchanger
1. Remove the screws on the heat exchanger
covers (1) and remove the covers. Mark the
covers so that you can put them back on the
correct side.
2. Press in the cooler core (5) slightly on one
side and pull it out from the other side.
3. Clean the cooler core on the outside with par-
affin-based engine detergent. Remove any
internal deposits using a round rod. Renew
the cooler core if it is damaged.
Do not use caustic soda as this could damage the
aluminium.
4. Renew damaged or hard O-rings (3).
5. Assemble the heat exchanger. Tighten the
M8 screws on the cover to 15 Nm (11 lb-ft).
