2. After warming up, turn off the engine.
3. To turn off the fuel pump, remove fuse No.1 (15A) from the fuse box located in the passenger compartment.
4. Start the engine and wait until the fuel runs out.
5. Remove all 4 spark plugs.
6. Install the compression tester adapter into the spark plug hole.
The measurement is made on each cylinder.
7. Press the accelerator pedal all the way down, crank the engine with the starter and measure the compression pressure.
Attention:
- Take measurements with a fully charged battery for a short time.
- Maximum compression pressure: 930 kPa (9.5 kg/cm²)/250 rpm.
8. Measure the compression on the other cylinders in the same way.
Pressure difference between cylinders: 200 kPa (2.0 kg/cm²)
If the compression pressure is low, check the following and repeat the measurement (if the engine condition is normal):
- Valve seating condition
- Damage to the cylinder head gasket
- Wear of piston rings
- Piston and cylinder wear
9. After checking, install all removed components.
