COOLING SYSTEM
General information
19A
Vehicles in the current range have cooling circuits with
the following basic specifications:
- hermetically-sealed pressurused circuit (expansion
chamber valve),
- circuit uses type « D » fluid,
- passenger compartment heating system via a
« heater matrix » radiator under the dashboard.
GENERAL PRECAUTION
Never use fluids other than the one specified: GLA-
CEOL RX (type D).
Never use coolants such as:
- ready-to-use coolant,
- anti-freeze (must be diluted; see directions on the
container).
When an operation requires the circuit to be completely
drained, it is essential to flush the circuit using clean
water, blow compressed air into it to remove as much
water as possible, fill and bleed the circuit, then
« measure the effective protection » of the circuit, i.e.:
- protection down to - 25 ˚C
±
2 ˚C for cold and tempe-
rate countries,
- protection down to - 40 ˚C
±
2 ˚C for very cold coun-
tries.
IMPORTANT
The circuits are designed to be pressurised, so be
careful at high temperatures (risk of serious burns).
Never remove the cap from the expansion bottle
while the engine is hot.
Similarly, take care when working under the bonnet,
as the radiator fan may start up unexpectedly.
WARNING
- The coolant helps to keep the engine running pro-
perly (heat exchange).
- The system does not operate using pure water.
