Tool for bleeding clutch hydraulics (Tool No. 21 5 030)
21 5 030 I
The clutch is hydraulically actuated by the master and slave
cylinders. With the self-adjusting clutch
(SAC), clutch disc
wear is automatically taken up through the self-adjusting
pressure plate springs, making pedal feel consistent through-
out the life of the clutch.
A soft or spongy feel to the clutch pedal, long pedal free-play,
or grinding noises
from the gears while shifting can all indi-
cate problems with the clutch hydraulics. In these circum-
stances it is best to
star? with a clutch fluid flush, followed, if
necessary, by replacement of the hydraulic parts.
NOTE-
The clutch hydraulic system shares the fluid reservoir and flu-
id with the brake hydraulic system.
Clutch hydraulic system,
bleeding and flushing
If the clutchlbralte fluid is murky or muddy, or has not been
changed within the last two years, flush the system and
change the fluid. Flushing the old fluid from the clutch lines is
done using a bralte system pressure bleeder.
- Remove brake fluid reservoir cap. Using a clean syringe, re-
move brake fluid from reservoir. Refill reservoir with clean
DOT
4 bralte fluid.
Worlting inside engine compartment, remove left
interiorven-
tilation filter housing:
Release 3 plastic taps
(A) on duct. Earlier models use a
single release latch.
Rotate duct inward to remove.
Disconnect electrical harness to hood position switch.
Remove filter housing cover.
Release spring lock
(B) on interior ventilation housing and
remove housing.

rod completely into slave cylinder.
Hold slave cylinder so that bleeder valve is at highest point.
Open bleeder valve and allow brake fluid to expel until
clean fluid comes out, free of air bubbles.
* Close bleeder valve and disconnect pressure bleeding
equipment from fluid reservoir.
Slowly unscrew and detach special tool 21

connect to brake fluid reservoir and apply pressurize.
Do not exceed a pressure of
2 bar (29 psi) when pressure
bleeding the

4 Disconnect bralte fluid level sensor connector (A) from fluid
reservoir. Remove reservoir cap.
. Using a clean syringe, empty bralte fluid reservoir.
Where applicable, disconnect hydraulic clutch system sup-
ply line from fluid reservoir duct
(5). Keep supply line sup-
ported and above clutch master cylinder to prevent air
bubbles from reaching clutch hydraulic system.
Where applicable, disconnect DSC system precharge
pump supply line from fluid reservoir duct
(C). Secure sup-
ply line in vertical position to prevent fluid loss.
Plug open brake fluid lines and ducts to prevent fluid leak-
age or contamination.
- Remove brake fluid reservoir by tilting sideways.
