BRAKE FLUID
BLEEDING
HINT:
If any work is done on the brake system or if air is suspected in
the brake lines, bleed the system of air.
NOTICE:
Do not let brake fluid remain on a painted surface. Wash it
off immediately.
1. FILL BRAKE RESERVOIR WITH BRAKE FLUID
Check the fluid level in the reservoir after bleeding each wheel.
Add fluid, if necessary. Fluid: SAE J1703 or FMVSS No.116 DOT3
2. BLEED MASTER CYLINDER

If the master cylinder has been disassembled or if the reservoir
becomes empty, bleed the air from the master cylinder.
(a) Disconnect the brake lines from the master cylinder.
(b) Slowly depress the brake pedal and hold it.
(c) Block off the outlet plugs with your fingers, and release the brake pedal.
(d) Repeat (b) and (c) 3 or 4 times.
3. CONNECT VINYL TUBE TO BRA KE CALIPER BLEED-
ER PLUG
Insert other end of the tube in a half −full container of brake fluid.

and mix it according to the manufacturer’s direc-
tions.

ene−glycol (but not more than 70 %) is recom-
mended.

(3) With the engine OFF, add new fluid through the oil
filler pipe.
Fluid type: ATF DEXRON ®II
Capacity:
Dry fill: 11.0 liters (11.6 US qts, 9.7 Imp. qts)
Drain and refill: 1.9 liters (2.0 US qts, 1.7 Imp. qts)
(4) Start the engine and shift the shift lever into all posi-
tions from P to L position and then shift into P posi-
tion.
(5) With the engine idling, check the fluid level. Add fluid up to the COOL level on the dipstick.
(6) Check the fluid level at the normal operating tem- perature 70 − 80° C (158 − 176°F) and add as nec-
essary.
NOTICE:
Do not overfill.
(d) Check the fluid leaks.
Check for leaks in the transmission.
If there are leaks, it is necessary to repair or replace O −rings,
Seal packings, oil seals, plugs or other parts.
(e) Inspect and adjust the throttle cable. (1) Check that the throttle valve is fully closed.
(2) Check that the inner cable is not slack.
(3) Measure the distance between the outer cable endand stopper on the cable.
Standard distance: 0 − 1 mm (0 − 0.04 in.)
If the distance is not standard, adjust the cable by the adjusting
nuts.
(f) Inspect and adjust the shift lever position. When shifting the shift lever from the N position to other
positions, check that the lever can be shifted smoothly
and accurately to each position and that the position indi-
cator correctly indicates the position.
If the indicator is not aligned with the correct position, carry out
the following adjustment procedures. (1) Loosen the nut on the control rod.
(2) Push the control rod fully rearward.

COMPRESSION
INSPECTION
HINT:
If there is lack of power, excessive oil consumption or poor fuel
economy, measure the compression pressure.
1. WARM UP AND STOP ENGINE
Allow the engine to warm up to normal operating temperature.
2. DISCONNECT DISTRIBUTOR CONNECTOR
3. REMOVE SPARK PLUGS (See page IG−1 )
4. CHECK CYLINDER COMPRESSION PRESSURE
(a) Insert a compression gauge into the spark plug hole.
(b) Fully open the throttle.
(c) While cranking the engine, measure the compression pressure.
HINT:
Always use a fully charged battery to obtain engine speed of
250 rpm or more.
(d) Repeat steps (a) through (c) for each cylinder.
NOTICE:
This measurement must be done in as short a time as pos-
sible. Compression pressure:
1,176 kPa (12.0 kgf/cm
2, 171 psi) or more
Minimum pressure: 883 kPa (9.0 kgf/cm
2, 128 psi)
Difference between each cylinder:
98 kPa (1.0 kgf/cm
2, 14 psi) or less
If the cylinder compression in one or more cylinders is low, pour
a small amount of engine oil into the cylinder through the spark
plug hole and repeat steps (a) through (c) for cylinders with low
compression.
If adding oil helps the compression, it is likely that
the piston rings and/or cylinder bore are worn or
damaged.
If pressure stays low, a valve may be sticking or
seating is improper, or there may be leakage past
the gasket.
5. REINSTALL SPARK PLUGS (See page IG−1 )

9. Rear valves of No. 6 cylinder
ADJUST VALVE CLEARANCE
(a) Remove the distributor (See page IG−10).
(b) Remove the camshafts (See page EM−28).
(c) Remove the adjusting shim with a small screwdriver.
(d) Determine the replacement adjusting shim size by follow- ing the Formula or Charts:
Using a micrometer, measure the thickness of the
removed shim.
Calculate the thickness of a new shim so that the
valve clearance comes within specified value.
T ....... Thickness of removed shim
A ....... Measured valve clearance
N ....... Thickness of new shim
Intake: N = T + (A − 0.20 mm (0.008 in.))
Exhaust: N = T + (A − 0.30 mm (0.012 in.))
Select a new shim with a thickness as close as pos-
sible to the calculated value.
HINT:
Shims are available in 17 sized in increments of 0.05 mm
(0.0020 in.), from 2.50 mm (0.0984 in.) to 3.30 mm (0.1299 in.).
