Compression Check: Testing and Inspection
1999 Suzuki Esteem GLX Sedan L4-1.6LSECTION Testing and Inspection
COMPRESSION CHECK
Check compression pressure on all four cylinders as follows:
1. Warm up engine.
2. Stop engine after warming up.
3. Disconnect ignition coil connector and remove ignition coils.
4. Remove all spark plugs and disconnect fuel injector wire harness at couplers.
5. Install special tool (Compression gauge) into spark plug hole.

(B): 09915-64510-002
(C): 09915-64530
(D): 09915-67010
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.
NOTE: For measuring compression pressure, crank engine at least 250 r/min. by using fully charged battery.
8. Carry out steps 5. through 7. on each cylinder to obtain four readings.
9. After checking, connect coupler of ignition coil and injectors and install spark plugs.

When to See a Mechanic
Stop DIY work and contact a certified mechanic immediately if any of the following apply:
- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
