Checking Coolant Level
The coolant reservoir with filler
neck is arranged away from the
radiator. To add coolant, the car
must be on level ground.
Warning:
Do not remove pressure cap on
coolant reservoir if engine tempera­
ture is above 90° C/194° F. Allow
engine to cool down before remov­
ing cap. The coolant reservoir
contains hot water and is under
pressure.
Using a rag, turn cap to first notch
to relieve excess pressure. If
opened immediately, hot scalding
fluid and steam will be blown out
under pressure.
If a small amount of coolant has to
be added (due to evaporation of
water), plain water can be used.
If a larger quantity of coolant has to
be added, a 50/50 mixture of water
and anti-corrosion/antifreeze
should be used:
The coolant level must reach:
• the mark indicated on the reser­
voir when the coolant is cold
• approximately
2
cm /
0.8
in higher
when the coolant is hot
The drain plugs are situated on the
R-H and L-H engine side and on
the radiator bottom.
