Oil capacities are defined according to the following methods
16
GENERAL
CAPACITIES (in litres)
Draining of the engine lubrication system by GRAVITY
Place the vehicle on horizontal ground (in the high position if
hydropneumatic suspension).
The engine should be hot (oil temperature 80°C).
Drain the sump by gravity.
Remove the oil filter cartridge (time for draining and drip-drip = 15
minutesapprox.).
Refit the cap with a new seal.
Refit a new oil filter cartridge.
Refill the engine with oil (see table for oil capacity).
Start the engine to fill the oil filter cartridge.
Stop the engine (allow to stabilise for 5 minutes).Draining of the engine lubrication system by SUCTION
Place the vehicle on horizontal ground (in the high position if
hydropneumatic suspension).
The engine should be hot (oil temperature 80°C).
Remove the oil by suction through the dipstick tube.
Remove the oil filter cartridge.
Maintain the suction of oil in the sump (15 minutesapprox.).
Refit a new oil filter cartridge.
Refill the engine with oil (see table for oil capacity).
Start the engine to fill the oil filter cartridge.
Stop the engine (allow to stabilise for 5 minutes).
WARNING: Remove the suction container before starting the engine.
ESSENTIAL: Systematically check the oil level using the oil dipstick.
