INSPECTION AFTER REMOVAL
Cylinder Head Bolts Outer Diameter
 Cylinder head bolts are tightened by plastic zone tightening
method. Whenever the size difference between “d1” and “d2”
exceeds the limit, replace them with a new one.
 If reduction of outer diameter appears in a position other than “d2”,
use it as “d2” point.
Cylinder Head Distortion
NOTE:
When performing this inspection, cylinder block distortion should be also checking. Refer to EM-127, "
Cylinder
Block".
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Never allow gasket debris to enter passages for engine oil or engine coolant.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions.
 If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install new cylinder head gasket.
2. Tighten cylinder head bolts in numerical order as shown with the
following procedure to install cylinder head.
CAUTION:
If cylinder head bolts are re-used, check their outer diame-
ters before installation. Follow the “Cylinder Head Bolts
Outer Diameter” measurement procedure.
a. Apply new engine oil to threads and seating surfaces of mount-
ing bolts.
b. Tighten all bolts.
c. Completely loosen.
CAUTION:Limit (“d1”–“d2”): 0.15 mm (0.0059 in)

ENGINE ASSEMBLY
 If items or work required are not covered by the engine section, follow the procedures in the applica-
ble sections.
 Always use the support point specified for lifting.
 Use either 2-pole lift type or separate type lift as best you can. If board-on type is used for unavoid-
able reasons, support at the rear axle jacking point with a transmission jack or similar tool before
starting work, in preparation for the backward shift of center of gravity.
 For supporting points for lifting and jacking point at rear axle, refer to GI-48, "
Garage Jack and
Safety Stand and 2-Pole Lift".
REMOVAL
Outline
Remove the engine and the transaxle assembly from the vehicle downward. Separate the engine and the tran-
saxle.
Preparation
