Downloaded from www.Manualslib.com manuals search engine PRESENTATION
THIS HANDBOOKsummarises the specifications, adjustments, checks and special features of CITROEN
private vehicles, not including UTILITY vehicles for which there exists a separate handbook.
The handbook is divided into nine groups representing the main functions :
GENERAL ENGINE INJECTION IGNITION CLUTCH, GEARBOX, DRIVESHAFTS AXLES,
SUSPENSION, STEERING BRAKES ELECTRICAL AIR CONDITIONING.
In each section, the vehicles are dealt with in the following order: C2C3C3 PLURIEL XSARA XSARA PICASSO BERLINGO (1)
and all models where applicable.
The information given in this handbook is based on vehicles marketed in EUROPE.
(1) NOTE : The BERLINGO familiale appears only in :
The correspondance tables for petrol and diesel engines.
The general chapter.

GENERAL
CAPACITIES (in litres)
Draining mandhod.
The oil capacities are defined according to the following mandhods.
1/
Vehicle on level surface (in high position, if equipped with hydropneumatic suspension).
2/Engine warm (oil temperature 80°C).
3/ Draining of the oil sump + removal of the cartridge (duration of draining + dripping = 15 min).
4/Refit plug + cartridge.
5/ Engine filling.
6/Engine starting (allowing the cartridge to be filled).
7/ Engine stopped (stationary for 5 min).
ESSENTIAL: Systematically check the oil level using the oil dipstick.

Draining.
IMPERATIVE:
The gearbox should be drained when the oil is warm (at least 60°C), to
eliminate the impurities in suspension in the oil.
NOTE:Draining is partial, the converter cannot be completely emptied.
Remove the drain plug
(1).
NOTE:Approx. 3 litres of oil should flow out.
Filling.
Refit the drain plug (1)(equipped with a new seal), tighten to2,4 ±0,2 m.daN.
Remove the oil filler cap (2).
Use tool [1].
Oil capacity for dry gearbox:

EW engine:5,85 litres.
DWengine:5,40 litres.
Oil remaining after draining:
3 litres(approx.).Quantity of oil to be put in :3 litres(approx.).Refit the oil filler cap (2)(equipped with a new seal), tighten to 2,4± 0,2 m.daN.
Initialise the oil wear counter (follow the diagnostic tool procedure).
