Coolant. Draining
The engine must be stopped before draining, and the
filler cap unscrewed.
WARNING! Do not open the filler cap (1) when
the engine is warm, except in emergencies.
Steam or hot fluid could spray out.
NOTE! Do not open filler cap (2).
On engines which are to be laid up or put in storage,
the engine cooling system should not be drained.
The coolant contains corrosion-inhibiting additives.
1. Remove the filler cap (1).
2. Open all drain points. Drain the coolant from the
radiator and engine block, using the drain hose.
The drain nipples are situated under the radiator
on the right side of the engine block.
3. Check that all coolant drains out. Deposits may
be found inside the drain plug/tap, and need to be
cleared away. There is otherwise a risk that cool-
ant could remain and cause frost damage. Check
whether the installation has any further taps or
plugs at the lowest points of the cooling water
pipes.
4. Shut any taps and check that the spring-loaded
covers on the nipples close completely. Install
the rubber plugs.
