Oil cooler, engine and reverse gear.
Cleaning
If a leak is suspected, the oil cooler must be disman-
tled from the engine or reverse gear and test
pressurised separately. This must be done by an
authorised workshop.
1. Open the drain cock (1) on the oil cooler. Detach
the coolant lines to and from the oil cooler.
2. Remove both end covers (2) and press out the in-
sert (can only be removed in one direction).
3. Wash the insert in e.g. white spirit and blow dry
2
with compressed air (or allow it to drip-dry). Clean
the inside of the tubes and the end covers using
suitable brushes. Clean the housing as well.
4. Refit the parts in reverse order. Use new greased
sealing rings.
5. Close the drain cock and open the sea cock. Start
the engine and check for leaks.
Maintenance: Seawater system
CAUTION! Close the sea cock before working
on the cooling system.
