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 checked. Refer to EM-219, "
Inspec-
tion After Disassembly".
1. Wipe off engine oil and remove water scale (like deposit), gasket, sealant, carbon, etc. with a scraper.
CAUTION:
Use utmost care not to allow gasket debris to enter passages for engine oil or water.
2. At each of several locations on bottom surface of cylinder head,
measure the distortion in six directions using straightedge (A)
and feeler gauge (B).
 If it exceeds the limit, replace cylinder head.
INSTALLATION
1. Install cylinder head gasket.
2. Apply new engine oil to threads and seating surface of bolts.
CAUTION:
If cylinder head bolts re-used, check their outer diameters before installation. Follow the "Cylinder
Head Bolts Outer Diameter" measurement procedure.
3. Install cylinder head, follow the steps below to tighten cylinder
head bolts in numerical order as shown.Limit (“d1” – “d2”): 0.15 mm (0.0059 in)

24. Remove the intake manifold to prevent the hanging chain from interfering. Refer to EM-156, "Removal
and Installation".
25. Install engine slinger to cylinder head front left side (A) and rear
right side (B) and support the engine position with a hoist.
26. Support engine and transaxle assembly with a hoist and secure the engine in appropriate position.
27. 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 something similar as the supporting
surface, secure a completely stable condition.
28. Remove torque rod (RH) (1), engine insulator (RH) (2) and
engine bracket (RH) (3).
29. Remove engine through bolt-securing nut (C).
30. 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, always check if any harnesses are left connected.
 During the removal operation, always 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 support the engine by placing a piece of wood under the engine oil
pan and transaxle oil pan. Securely support the engine slingers with a hoist.
31. When the engine hoisting is not performed simultaneously, install engine slinger to cylinder head front left
side and rear right side. Refer to EM-207, "
Component".
32. Remove starter motor. Refer to STR-24, "
Removal and Installation".
33. Lift with a hoist and position above engine.
34. Separate the engine and the transaxle. Refer to EM-207, "
Component" .
