• Dowel pins are used for several parts alignment. When replacing and reassembling parts with dowel pins,

check that dowel pins are installed in the original position.

• Must cover openings of engine system with a tape or equivalent, to seal out foreign materials.
• Mark and arrange disassembly parts in an organized way for easy troubleshooting and reassembly.
• 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.

ASSEMBLY AND INSTALLATION

• 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 engine oil or engine 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. 

• After disassembling, or exposing any internal engine parts, change engine oil and replace oil filter with a new

one.

• Release air within route when refilling after draining engine coolant. 
• After repairing, start the engine and increase engine speed to check engine coolant, fuel, engine oil, and

exhaust gases for leakage.

Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.

1.

Pull out oil level gauge and wipe it clean.

2.

Insert oil level gauge and check the engine oil level is within the
range shown in the figure.

3.

If it is out of range, adjust it.

ENGINE OIL APPEARANCE

• Check engine oil for white turbidity or heavy contamination.
• If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.

Repair or replace damaged parts.

ENGINE OIL LEAKAGE

Check for engine oil leakage around the following areas:
• Oil pans (lower and upper)
• Oil pan drain plug
• Oil pressure switch
• Oil temperature sensor
• Oil filter
• Water pump cover
• Oil cooler 
• Valve timing control covers (bank 1 and bank 2)
• Intake valve timing control solenoid valve (bank 1 and bank 2)
• Mating surface between cylinder head and rocker cover
• Mating surface between front timing chain case and rear timing chain case
• Mating surface between rear timing chain case and cylinder head
• Mating surface between rear timing chain case and cylinder block
• Mating surface between rear timing chain case and oil pan (upper)
• Mating surface between cylinder block and cylinder head
• Crankshaft oil seals (front and rear)
• Camshaft position sensor (PHASE) 

OIL PRESSURE CHECK

WARNING:

• Be careful not to get burn yourself, as engine oil may be hot.
• Oil pressure check should be done in “Parking position”.

1.

Check the engine oil level.

2.

Remove splash guard (RH). Refer to 

EXT-26, "FENDER PROTECTOR : Exploded View"
