Compression Check
Check compression pressure on all 4 cylinders as follows:
1) Warm up engine.
2) Stop engine after warming up.
NOTE:
After warming up engine, place transmission gear shift lever in “Neutral” (shift selector lever to “P” range for A/T model), and set parking brake and block drive wheels.
3) Disconnect accelerator cable (1) from clamp (2) (For left hand steering vehicle only).
4) Remove cylinder head upper cover (3).
5) Disconnect ignition coil couplers (1).
6) Remove ignition coil assemblies (2) with high-tension cord (3).
7) Remove all spark plugs.
8) Disconnect fuel injector wires (4) at the coupler.
9) Install special tools (Compression gauge) into spark plug hole.
Special Tool
(A) : 09915–64510–001
(B) : 09915–64510–002
(C) : 09915–64530
(D) : 09915–67010
10) Disengage clutch (1) (to lighten starting load on engine) for M/T vehicle, and depress accelerator pedal (2) all the way to make throttle fully open.
11) Crank engine with fully charged battery, and read the highest pressure on compression gauge.
NOTE:
• For measuring compression pressure, crank engine at least 250 rpm by using fully charged battery.
• If check results are below the limit valve, check installation condition for special tool.
Compression pressure
Standard : 1400 kPa (14.0 kg/cm², 199.0 psi)
Limit : 1100 kPa (11.0 kg/cm², 156.0 psi)
Max. difference between any two cylinders : 100 kPa (1.0 kg/cm², 14.2 psi)
12) Carry out Steps 9) through 11) on each cylinder to obtain 4 readings.
13) After checking, install spark plugs and ignition coil assemblies (1) with high-tension cord (2).
14) Connect ignition coil couplers (3).
15) Connect fuel injector wires (4) at the coupler.
16) Check cylinder head upper cover gasket for deterioration and then install it into groove of cylinder head upper cover (1) securely.
17) Install cylinder head upper cover with gasket on to cylinder head cover.
18) Connect accelerator cable (2) to clamp (3) (For left hand steering vehicle only).
