Engine Coolant
This subject is covered in SECTION 6 ENGINE
COOLING SYSTEM.
Exhaust Line and Muffler
Inspect each exhaust line connection for tight-
ness, and examine muffler and other parts for
evidence of breakage and leakage of gases.
Repair or replace defective parts, if any.
Compression Pressure Measurement
Check compression pressure on all four cylinders
as follows:
1) Warm up engine.
2) Stop engine after warming up.
3) Remove all spark plugs and disconnect
high tension cord from ignition coil.
4) Install compression gauge (special tool) into
spark plug hole.
5) Disengage clutch (to lighten starting load on
engine), and depress accelerator pedal all
the way to make throttle full-open.
6) Crank engine with fully charged battery, and
read the highest pressure on compression
gauge.

7) Carry out steps 4) through 6) on each cylin-
der to obtain four readings.
NOTE:
Compression pressure value is measured by using
compression gauge (Special tool 09915-64510).
Oil Pump Discharge Pressure Measurement
NOTE:
Prior to checking oil pressure, check the follow-
ing.
