Precaution for Procedur e without Cowl Top Cover INFOID:0000000004307110
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Precaution for Drain Coolant INFOID:0000000004307112
• Drain coolant when engine is cooled.
Precaution for Disco nnecting Fuel Piping INFOID:0000000004307113
• Before starting work, make sure no fire or spark producing items are in the work area.
• Release fuel pressure before disassembly.
• After disconnecting pipes, plug openings to stop fuel leakage.
Precaution for Removal and Disassembly INFOID:0000000004307114
• When instructed to use special service tools, use the spec ified tools. Always be careful to work safely, avoid
forceful or uninstructed operations.
• Exercise maximum care to avoid damage to mating or sliding surfaces.
• Cover openings of engine system with tape or the equiva lent, if necessary, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and assembly.
• When loosening nuts and bolts, as a basic rule, start with the one furthest outside, then the one diagonally opposite, and so on. If the order of loosening is specif ied, do exactly as specified. Power tools may be used
where noted in the step.
Precaution for Inspection, Repair and Replacement INFOID:0000000004307115
• Before repairing or replacing, thoroughly inspect parts. Inspect new replacement parts in the same way, and
replace if necessary.
Precaution for Assembly and Installation INFOID:0000000004307116
• Use torque wrench to tighten bolts or nuts to specification.
• When tightening nuts and bolts, as a basic rule, equally tighten in several different steps starting with the ones in center, then ones on inside and outside diagonally in this order. If the order of tightening is specified,
do exactly as specified.
• Replace with new gasket, packing, oil seal or O-ring.
• Thoroughly wash, clean, and air-blow each part. Carefully check oil or coolant passages for any restriction
and blockage.
• Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.
• Release air within route after draining coolant.
• Before starting engine, apply fuel pressure to fuel lines with turning ignition switch ON (with engine stopped). Then make sure that there are no leaks at fuel line connections.
• After repairing, start engine and increase engine speed to check coolant, fuel, oil, and exhaust systems for leakage. PIIB3706J

CHECKING COMPRESSION PRESSURE 1. Warm up engine thoroughly. Then, stop it.
2. Release fuel pressure. Refer to EC-574, " Fuel Pressure Check " (Type 1) or
EC-1086, " Fuel Pressure
Check " (Type 2).
3. Disconnect fuel pump fuse (1) to avoid fuel injection during mea- surement.
4. Remove engine cover. Refer to EM-141, " Component " .
5. Remove ignition coil and spark plug from each cylinder. Refer to EM-153 .
6. Connect an engine tachometer (not required in use of CONSULT-III).
7. Install a suitable compression tester (B) with an adapter (A) onto spark plug hole.
• Use the adapter whose picking up end inserted to spark plug hole is smaller than 20 mm (0.79 in) in diameter. Otherwise, it
may be caught by cylinder head during removal.
8. With accelerator pedal fully depressed, turn ignition switch to “START” for cranking. When the gauge pointer stabilizes, read the compression pressure and the engine rpm. Perform these steps to check each
cylinder.
Compression pressure: Unit: kPa (bar, kg/cm2
