THROTTLE BODY AND INTAKE MANIFOLD
REMOVAL
1) Relieve fuel pressure according to procedure described in
“FUEL PRESSURE RELIEF PROCEDURE” of Section 6.
2) Disconnect negative cable at battery.
3) Drain cooling system.
WARNING:
To help avoid danger of being burned, do not remove
drain plug (2) and radiator cap while engine and radiator
(1) are still hot. Scalding fluid and steam can be blown out
under pressure if plug and cap are taken off too soon.

WARNING:
For vehicles equipped with Supplement Restraint (Air Bag) System:

Service on and around the air bag system components or wiring must be performed only by an autho-
rized SUZUKI dealer. Refer to “Air Bag System Components and Wiring Location View” under “Gener-
al Description” in air bag system section in order to confirm whether you are performing service on
or near the air bag system components or wiring. Please observe all WARNINGS and “Service Precau-
tions” under “On-Vehicle Service” in air bag system section before performing service on or around
the air bag system components or wiring. Failure to follow WARNINGS could result in unintentional
activation of the system or could render the system inoperative. Either or these two conditions may
result in severe injury.

Technical service work must be started at least 90 seconds after the ignition switch is turned to the
“LOCK” position and the negative cable is disconnected from the battery. Otherwise, the system may
be activated by reserve energy in the Sensing and Diagnostic Module (SDM).

ON-VEHICLE SERVICE
COMPRESSION CHECK
Check compression pressure on all four cylinders as follows:
1) Warm up engine.
2) Stop engine after warming up.
NOTE:
After warming up engine, place transmission gear shift le-
ver in “Neutral” (shift selector lever to “P” range for A / T
model), and set parking brake and block drive wheels.
3) Remove ignition coil assemblies (1) and all spark plugs (2) refer-
ring to Section 6F.
WARNING:
Failure in disconnecting couplers from ignition coil as-
semblies can cause spark to occur in engine room possi-
bly resulting in a dangerous explosion.
4) Disconnect fuel injector wire harness at couplers (2).
5) Install special tools (Compression gauge) into spark plug hole.

6) Disengage clutch (to lighten starting load on engine) for M / T
model, and depress accelerator pedal all the way to make
throttle valve full-open.
7) Crank engine with fully charged battery, and read the highest
pressure on compression gauge.

8) Carry out steps 5) through 7) on each cylinder to obtain four
readings.
9) After checking, connect couplers to fuel injectors securely and
install spark plugs and ignition coil assemblies.
