General Description
MECHANICAL
8. ENGINE MOUNTING
C: CAUTION
•Wear work clothing, including a cap, protective
goggles and protective shoes during operation.
•Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
•Keep the disassembled parts in order and pro-
tect them from dust and dirt.
•Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
•Be careful not to burn yourself, because each
part on the vehicle is hot after running.
•Be sure to tighten fasteners including bolts and
nuts to the specified torque.
•Place shop jacks or rigid racks at the specified
points.
•Before disconnecting connectors of sensors or
units, be sure to disconnect the ground cable from
the battery.
•All parts should be thoroughly cleaned, paying
special attention to engine oil passages, pistons
and bearings.
•Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
•Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
•All removed parts, if to be reused, should be re-
installed in the original positions and directions.
•Bolts, nuts and washers should be replaced with
new ones as required.
•Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
•Remove or install the engine in an area where
chain hoists, lifting devices, etc. are available for
ready use.
•Be sure not to damage coated surfaces of body
panels with tools, or not to stain seats and windows
with coolant or oil. Place a cover over fender, as re-
quired, for protection.
•Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
•Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.

Compression
MECHANICAL
2. Compression
A: INSPECTION
CAUTION:
After warming-up, engine becomes very hot. Be
careful not to burn yourself during measure-
ment.
1) After warming-up the engine, turn the ignition
switch to OFF.
2) Make sure that the battery is fully charged.
3) Release the fuel pressure.
4) Remove all the spark plugs.
5) Check the starter motor for satisfactory perfor-
mance and operation.
6) Hold the compression gauge tightly against the
spark plug hole.
NOTE:
When using a screw-in type compression gauge,
the screw (put into cylinder head spark plug hole)
should be less than 18 mm (0.71 in) long.
7) Fully open the throttle valve.
8) Crank the engine by means of the starter motor,
and read the maximum value on the gauge when
the pointer is steady.
9) Perform at least two measurements per cylinder,
and make sure that the values are correct.
Compression (350 rpm and fully open throttle):
Standard:
1,275 — 1,471 kPa (13.0 — 1.50 kgf/cm2,
185 — 213 psi)
Service limit:
1,128 kPa (11.5 kgf/cm2, 164 psi)

Engine Oil Pressure
MECHANICAL
6. Engine Oil Pressure
A: INSPECTION
1) Remove the oil pressure switch from cylinder
block.
2) Connect the oil pressure gauge hose to cylinder
block.
3) Connect the ground cable to the battery.
4) Start the engine, and measure the oil pressure.
OIL PRESSURE (at oil temperature of 80°C
(176°F)):
Standard:
135 kPa (1.4 kgf/cm2, 20 psi) or more (at
600 rpm)
500 kPa (5.1 kgf/cm2, 73 psi) or more (at
5,000 rpm)
CAUTION:
•If the oil pressure is out of specification,
check oil pump, oil filter and lubrication line.
•If the oil pressure warning light is turned ON
and oil pressure is in specification, replace the
oil pressure switch.
5) After measuring the oil pressure, install the oil
pressure switch.
Tightening torque:
25 N·m (2.5 kgf-m, 18 ft-lb)
