1. Warm up engine.
2. Turn ignition switch OFF.
3. Release fuel pressure.
Refer to EC-38, ªReleasing Fuel Pressureº.
4. Remove ignition coils.
5. Remove spark plugs.
+Clean area around plug with compressed air before removing
the spark plug.

6. Attach a compression tester to No. 1 cylinder.
7. Depress accelerator pedal fully to keep throttle valve wide
open.
8. Crank engine and record highest gauge indication.
9. Repeat the measurement on each cylinder as shown above.
+Always use a fully-charged battery to obtain specified
engine speed.

10. If 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 retest compression.
+If adding oil improves cylinder compression, piston rings
may be worn or damaged. If so, replace piston rings after
checking piston.
+If pressure stays low, a valve may be sticking or seating
improperly. Inspect and repair valve and valve seat. Refer
to SDS, EM-70. If valve or valve seat is damaged
excessively, replace them.
+If compression in any two adjacent cylinders is low and if add-
ing oil does not improve compression, there is leakage past the
gasket surface. If so, replace cylinder head gasket.
11. Reinstall spark plugs, ignition coils and fuel pump fuse.
12. Perform ªSelf-diagnosis Procedureº referring to EC-68, ªHow
to Erase DTCº if any DTC appears.

1. Inspect for cracks, fraying, wear or oil adhesion. If necessary,
replace with a new one.
+When replacing belt, make sure the new belt has the same
number of ribs as the old one.
2. Inspect drive belt deflections by pushing on the belt midway
between pulleys.
3. Turn crankshaft two revolutions and recheck drive belt deflec-
tion.
+Inspect drive belt deflection when engine is cold.
+Adjust if belt deflections exceed the limit.
