4 Checking coolant level
Check the coolant level in the header tank.
This has to be checked when the engine
is cold.
Remove the cap of the filler neck on the
heat exchanger.
The level of the coolant must be approx.
1 cm (3/8”) below the lower edge of the
filler neck.
If necessary, top up.
When topping up coolant, remove the
bolt from the upper side of the thermostat
cover, so that air can escape from the
cooling system.
Wa r N i N g
Never open the cap on the header tank
when the engine is at operating tempera-
ture.
5 Topping up coolant

with a mixture of anti-freeze (40 %) and tap
water (60 %) or with a special coolant. For
specification, see page 67
