Inspecting engine oil level
When inspecting, pay attention to the following points:
Before inspecting, warm up the engine to normal temper-
ature.
Wait at least 3 minutes after switching off the engine to al-
low the oil to flow back into the oil pan.
–Withdraw dipstick, wipe off with a clean cloth and re-
insert dipstick fully.
–Withdraw dipstick once again and read off oil level.
Fig. 1: Oil dipstick version I
Fig. 2: Oil dipstick version ll
The oil level in area -a-
–The oil must be topped up. It is sufficient when the oil
level rises to the area -b-.
The oil level in area -b-
–The oil can be topped up. It is possible that the oil level
will rise to the area -c-.
The oil level in area -c-
–The oil must not be topped up.
♦The oil level must not, under any circumstances, be
above area -a- - danger of damage to the catalytic
converter.
♦The vehicle must be standing on level ground when
measuring the oil level. Wait a few minutes after
switching off the engine to allow the oil to flow back
into the oil pan.
Change engine oil
♦The engine oil should always be changed, if possible,
when the engine is at normal operating temperature.
♦If the engine oil is drained, replace the seal of the oil
drain plug.

which can also be used as an all-season oil, except in ex-
tremely cold climatic zones.

The given specifications must be indicated on the can in-
dividually or together with other specifications.
Only use engine oils:
QGO, QG2

Oils may be intermixed when topping up.
In exceptional cases:
Multigrade oils according to ACEA A2 or A3. Such oils
must only be used once for topping up within the speci-
fied oil change interval if, in exceptional cases, no ap-
proved engine oil is available.

Specification VW 505 01 or VW 505 00 (oil according
to VW 505 00 cannot be used for TDI PD - engines)
Oils may be intermixed when topping up.

–Close the oil filler opening again.
–Start engine and check for leaks.
–Check the engine oil level again and top up with oil if
necessary.
–Wait at least 3 minutes after topping up the oil again
before inspecting the oil level again.
–Install the noise insulation.
The oil level must not be above the -max- marking to
avoid damage to the catalytic converter. See Inspecting
engine oil level ⇒02-3 page 8.
Inspecting antifreeze protection, replen-
ishing coolant additive if necessary
♦Collect drained coolant for proper disposal.
♦Observe the disposal instructions for the drained cool-
ant.
Special tools, test and measuring equipment and
auxiliary items required
♦Refractomer -T10007-
Inspecting antifreeze protection of the coolant
♦The refractometer -T10007- may, for example, be
used for inspecting the antifreeze protection of the
coolant.
Note
WARNING!
Coolant additives are toxic!
Do not inhale coolant vapours, do not swallow
coolant, avoid contact with skin and eyes; haz-
ardous if consumed!

–Extract a small quantity of coolant with the pipette and
place on the measuring glass. Hold unit against a light
source and read off the temperature down to which
antifreeze protection exists on the scale for ethylene
glycol.
♦Antifreeze protection must be ensured down to about
-25 C.
♦Down to about -35 C in countries with an arctic cli-
mate.
♦If a greater antifreeze concentration is required for cli-
matic reasons, the concentration may be increased up
to 60 % (i.e. antifreeze protection down to about -40
C). Any further increase in concentration increase
would reduce the antifreeze protection and impair
cooling efficiency.
Replenishing coolant additive
♦Coolant additive G12 - red in colour, complying with
standard TL VW 774 D, must not be mixed with other
coolant additives which comply with standard TL VW
774 C(B) -bluish-green in colour-. If these two coolant
additives are mixed the coolant will turn brown. Brown
coolant must be drained immediately, the cooling sys-
tem flushed out with drinking water and filled with
fresh coolant. If this is not done the engine and cooling
system may suffer damage.
♦Coolant additives complying with standard TL VW 774
C (G11) -bluish-green in colour-, must only be used
for topping up on vehicles fitted with a cooling system
which is already filled with this coolant.
♦Vehicles produced as of MJ 03 are filled with coolant
additive G12 PLUS which has a lilac colour and con-
forms with the standard TL VW 774 F.
♦Coolant additive G12 PLUS must only be mixed with
coolant additives G12 and G11.
♦Coolant additive G12 PLUS is recommended for use
on all vehicles when changing the coolant.
If the vehicle is filled with the recommended coolant and
the antifreeze protection is not adequate, drain part of the
coolant from the cooling system.
–After this, fill the cooling system with concentrated
coolant additive.
The coolant capacity is:

–Perform a test drive and again check the coolant anti-
freeze protection.
Inspecting coolant level (volume)
–The coolant expansion reservoir is located on the right
of the engine compartment.
–Inspect coolant level only when the engine is not run-
ning.
Specified coolant level for the Inspection Service:
•Engine cold: between„MAX“ and „MIN“ marking.
•Engine warm: slightly above the „MAX“ marking.
♦The cooling system is filled all year round with a mix-
ture of water and antifreeze/anti-corrosion agent.
Coolant additives prevent damage from frost and cor-
rosion and the accumulation of lime scale while also
raising the boiling point of the coolant. For these rea-
sons the cooling system must always be filled all year
round with radiator antifreeze and anti-corrosion
agent offering these properties.
♦Coolant additive G12 - red in colour, complying with
standard TL VW 774 D, must not be mixed with other
coolant additives which comply with standard TL VW
774 C(B) -bluish-green in colour-. If these two coolant
additives are mixed the coolant will turn brown. Brown
coolant must be drained immediately, the cooling sys-
tem flushed out with drinking water and filled with
