Precaution for Procedur e without Cowl Top Cover INFOID:0000000004784258
When performing the procedure after removing cowl top cover, cover
the lower end of windshield.
Precaution for Drain Coolant INFOID:0000000004784260
• Drain coolant when engine is cooled.
Precaution for Disco nnecting Fuel Piping INFOID:0000000004784261
• 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:0000000004784262
• 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:0000000004784263
• 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:0000000004784264
• 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

Measure the diameter of valv
e stem with a micrometer (A).
Valve Guide Inner Diameter Measure the inner diameter of valve guide with a bore gauge.
Valve Guide Clearance (Valve guide clearance) = (Valve guide inner diameter) – (Valve stem diameter).
• If it exceeds the limit, replace valve guide and/or valve.
VALVE GUIDE REPLACEMENT When valve guide is removed, replace with oversized [0.2 mm (0.008 in)] valve guide.
1. To remove valve guide, heat cylinder head to 110 ° to 130 °C
(230 ° to 266 °F) by soaking in heated oil (A).
2. Drive out valve guide using suitable tools. WARNING:
Cylinder head contai ns heat, when workin g, wear protective
equipment to avoid getting burned. Standard
Intake : 5.465 - 5.480 mm (0.2152 - 0.2157 in)

24. Remove A/C compressor with piping connected from t
he engine. Temporarily secure it on the vehicle side
with a rope to avoid putting load on it. Refer to MTC-80, " Removal and Installation of Compressor -
MR18DE " .
25. Remove the intake manifold to prevent the hanging chain from interfering. Refer to EM-141, " Compo-
nent " .
26. Install engine slinger to cylinder head front left side (A) and rear right side (B) and support the engine position with a hoist.
27. Support engine and transaxle assembly with a hoist and secure the engine in appropriate position.
28. Use a manual lift table caddy (A) or equivalently rigid tool such as a transmission jack. Securely support bottom of the engine
and the transaxle, and simultaneously adjust hoist tension.
CAUTION:
Put a piece of wood or someth ing similar as the supporting
surface, secure a completely stable condition.
29. Remove torque rod (RH) (1), engine insulator (RH) (2) and engine bracket (RH) (3).
30. Remove engine through bolt-securing nut (C).
31. Remove the engine and the transaxle assembly from the vehicle downward by carefully operating sup- porting tools.
CAUTION:
• During the operation, make sure that no part interferes with the vehicle side.
• Before and during this lifting, alw ays check if any harnesses are left connected.
• During the removal operation, alw ays be careful to prevent the vehicle from falling off the lift due
to changes in the center of gravity.
• If necessary, support the vehicle by setting jack or suitable tool at the rear.
• During operation, securely suppor t the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely sup port the engine slingers with a hoist.
32. Remove starter motor. Refer to SC-9 .
33. Separate the engine and the transaxle and mount the engine on a suitable engine stand. Refer to AT-232(A/T models),
CVT-182 or
CVT-354 (CVT models) or
MT-58 (M/T models).
