Clutch Fluid

8. Clutch Fluid

A: INSPECTION

1) Park the vehicle on a level surface.
2) Inspect the fluid level using the scale on the out-
side of reservoir tank. If the level is below “MIN”,
add fluid to bring it up to “MAX”, and then inspect
for leakage.

B: REPLACEMENT

CAUTION:
• The FMVSS No. 116, fresh DOT3 or 4 brake
fluid must be used.
• When loosening the bleeder screw, cover the
bleeder with cloth to prevent brake fluid from
being splashed over surrounding parts.
• Avoid mixing different brands of brake fluid
to prevent the quality of fluid from degrading.
• Be careful not to allow dirt or dust to get into
the reservoir tank.

NOTE:
• During bleeding operation, keep the clutch reser-
voir tank filled with brake fluid to eliminate entry of
air.
• Clutch pedal operation must be very slow.
• Bleed air from the oil line with help of a co-work-
er.
• The necessary amount of brake fluid is approx.
70 m

2 (2.4 US fl oz, 2.5 Imp fl oz) for total clutch

system.
1) Remove the air intake chamber. <Ref. to
IN(H4SO 2.0)-7, REMOVAL, Air Intake Chamber.>
2) Drain the brake fluid from reservoir tank.
3) Refill the reservoir tank with recommended
brake fluid.

Recommended brake fluid:

FMVSS No. 116, fresh DOT3 or 4 brake fluid

4) Drain all the contaminated fluid in the same
method as air bleeding.

NOTE:
Keep the clutch reservoir tank filled with brake fluid
to eliminate entry of air.

Clutch Fluid Air Bleeding

9. Clutch Fluid Air Bleeding

A: PROCEDURE

1. 5MT MODEL

NOTE:
Bleed air from the oil line with help of a co-worker.
1) Remove the air intake chamber. <Ref. to
IN(H4SO 2.0)-7, REMOVAL, Air Intake Chamber.>
2) Remove the intercooler. <Ref. to IN(H4DOTC)-
12, REMOVAL, Intercooler.>
3) Fit one end of a vinyl tube into the air bleeder of
operating cylinder and the other end into a brake
fluid container.

4) Slowly depress the clutch pedal and keep it de-
pressed. Open the air bleeder to discharge air to-
gether with the fluid.
Release the air bleeder for 1 or 2 seconds. Next,
with the bleeder closed, slowly release the clutch
pedal.

CAUTION:
Cover the bleeder with cloth to prevent brake 
fluid from being splashed over surrounding 
parts when loosening the bleeder.

5) Repeat the step 4) until there are no more air
bubbles in the vinyl tube.

6) Tighten the air bleeder.

Tightening torque:

T: 8 N

⋅

m (0.8 kgf-m, 5.8 ft-lb)

7) After depressing the clutch pedal, make sure
that there are no leaks evident in the entire clutch
system.
8) After bleeding air from the clutch system, ensure
that clutch operates properly.

2. 6MT MODEL

NOTE:
Bleed air from the oil line with help of a co-worker.
1) Remove the air cleaner case. <Ref. to
IN(H6DO)-5, REMOVAL, Air Cleaner Case.>
2) Fit one end of a vinyl tube into the air bleeder of
master cylinder and the other end into a brake fluid
container.
3) Remove the operating cylinder.

NOTE:
Do not remove the clutch hose.

4) Fix the piston with clamp to avoid the piston from
jumping out.
