• Do not damage or scratch the outer circumference of

the rear oil seal.

• Tap until flattened with the front edge of the oil seal retainer. 

3. Installation of the remaining components is in the reverse order of removal. Refer to 

TM-206, "Removal

and Installation (2WD)"

, 

TM-208, "Removal and Installation (4WD)"

.

CAUTION:

• When replacing an engine or transmission you must make sure the dowels are installed cor-

rectly during re-assembly.

• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of

drivetrain components.

• Cylinder head bolts are tightened by plastic zone tightening

method. Whenever the size difference between d1 and d2 exceeds

the limit, replace the bolt with a new one. 

• If reduction of diameter appears in a position other than d2, use it

as d2 point.

INSTALLATION

1. Install a new cylinder head gasket.
2. Install the cylinder head. Follow the steps below to tighten the

bolts in the numerical order shown.

CAUTION:

• If cylinder head bolts are re-used, check their diameters

before installation. Follow the "Cylinder Head Bolts Diam-

eter" procedure.

a. Apply engine oil to threads and seating surface of the bolts.

b. Measure the tightening angle using Tool.

CAUTION:

Measure the tightening angle using Tool. Do not measure

visually. 

3. Installation of the remaining components is in the reverse order of removal.

INSPECTION AFTER INSTALLATION

• Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required

quantity, fill to the specified level. Refer to 

GI-15, "Recommended Chemical Products and Sealants"

.

• Use procedure below to check for fuel leakage.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leak-

age at connection points.

• Start engine. With engine speed increased, check again for fuel leakage at connection points.

• Run engine to check for unusual noise and vibration.

• Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including

engine oil and engine coolant.

• Bleed air from passages in lines and hoses, such as in cooling system.

• After cooling down engine, again check oils/fluids including engine oil and engine coolant. Refill to specified

level, if necessary.
