Precaution for Removal and Disassembly

1. When instructed to use special service tools, use the specified tools. Always be careful to work safely, avoid forceful or uninstructed operations.
2. Exercise maximum care to avoid damage to mating or sliding surfaces.
3. Cover openings of engine system with tape or equivalent, if necessary, to seal out foreign materials.
4. Mark and arrange disassembly parts in an organized way for easy troubleshooting and reassembly.
5. 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 specified, do exactly as specified. Power tools may be used in the step.

Precaution for Assembly and Installation

1. Use torque wrench to tighten bolts or nuts to specification.
2. 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.
3. Replace with new gasket, packing, oil seal or O-ring.
4. Thoroughly wash, clean, and air-blow each part. Carefully check engine oil or engine coolant passages for any restriction and blockage.
5. Avoid damaging sliding or mating surfaces. Completely remove foreign materials such as cloth lint or dust. Before assembly, oil sliding surfaces well.
6. Release air within route when refilling after draining engine coolant.
7. 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.
8. After repairing, start engine and increase engine speed to check engine coolant, fuel, engine oil, and exhaust gasses for leakage.

INSTALLATION

Installation is in the reverse order of removal.

Note. Turn crankshaft pulley clockwise several times to equalize tension between each pulley. Confirm tension of drive belt indicator (fixed side) is within the allowable working range.

23. Install front and rear engine slingers. Engine slinger torque Front engine slinger: 48.1 N.m (4.9 kg-m, 35 ft-lb) Rear engine slinger: 22.0 N.m (2.2 kg-m, 16 ft-lb)
24. Remove transmission. Refer to [ «TRANSMISSION ASSEMBLY: REMOVAL AND INSTALLATION FROM VEHICLE»(ref-375726-S08109484552010102800000) (M/T models), [ «TRANSMISSION ASSEMBLY: REMOVAL AND INSTALLATION FOR QR25DE»(ref-375705-S22438690232010102800000) ] (A/T models).
25. Lift with hoist and secure the engine in position.
26. Remove engine assembly from vehicle, avoiding interference with vehicle body. CAUTION: Before and during this lifting, always check if any harnesses are left connected.
27. Remove the parts that may restrict installation of engine to engine stand. NOTE: The procedure is described assuming that you use a engine holding the surface, to which transmission is installed. Remove drive plate (A/T models) or flywheel (M/T models). Holding crankshaft pulley bolts, lock crankshaft to remove flywheel or drive plate bolts. Loosen bolts diagonally. CAUTION: Be careful not to damage drive plate. Especially avoid deforming and damaging of signal plate teeth (circumference position). Place the drive plate with signal plate surface facing other than downward. Keep magnetic materials away from signal plate. CAUTION: Use an engine stand that has a load capacity [approximately 240kg (529 lb) or more] large enough for supporting the engine weight. If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the potential risk of overturning the stand. Remove fuel tube and fuel injector assembly. Refer to [ «FUEL INJECTOR AND FUEL TUBE: REMOVAL AND INSTALLATION [QR25DE]»(ref-375719-S03811651132010102800000) ] Remove intake manifold. Refer to [ «INTAKE MANIFOLD: REMOVAL AND INSTALLATION»(ref-375720-S41952777752010102800000) ]. Remove rocker cover. Refer to [ «ROCKER COVER: REMOVAL AND INSTALLATION [QR25DE]»(ref-375720-S12046884292010102800000) ]. Other removable brackets. CAUTION: Before removing the hanging chains, make sure the engine stand is stable and there is no risk of overturning.
28. Remove generator. Refer to [ «GENERATOR: REMOVAL AND INSTALLATION - QR25DE MODELS»(ref-375739-S09762652382010102800000) ]
29. Remove engine mounting insulator bracket (upper) with power tool.

Installation is in the reverse order of removal.

1. Do not allow engine oil to get on engine mounting insulator. Be careful not to damage engine mounting insulator.
2. When installation directions are specified, install parts according to the direction marks on them referring to the figure of components.
3. Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
