Filling with coolant using a
pump
1. Connect a suitable pump with a hose to the
drain valve (arrowed).
2. Open air bleed on intercooler (arrow).
3. Open drain valve and pump coolant into en-
gine at 0.5 bar minimum.
4. When coolant emerges from the bleed valve,
close the bleed valve.
5. Top expansion tank up to the overflow.
6. Close drain valve.
7. Check pressure cap is in perfect condition
and clean sealing faces if necessary.
8. Position breather valve on filler neck and
close.
9. Start engine (→ Page 47).
10. After 10 seconds of running the engine with-
out load, shut down the engine (→ Page 49).
11. Turn pressure cap of coolant expansion tank
counterclockwise until the first stop and al-
low pressure to escape.
12. Turn pressure cap counterclockwise and re-
move.
13. Check coolant level (→ Page 126) and top up
coolant as required:
a) Top up with coolant via expansion tank
until the coolant level is constant at the
overflow.
