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)

ENGINE ASSEMBLY
 When installation directions are specified, install parts according to the directions. Refer to EM-207, "Com-
ponent".
 Prior to installing the upper torque rod, apply a light coat of silicone
lubricant (A) to the washer facing side of the bushing inner tube as
shown.
NOTE:
 Apply silicone lubricant (A) by dabbing the outward facing tube
surface with a sponge or suitable tool.
 Do not apply excess lubricant.
 Make sure that each mounting insulator is seated properly, and tighten nuts and bolts.
 Tighten engine mounting insulator (RH) bolts in the numerical
order shown.
INSPECTION AFTER INSTALLATION
Inspection for Leaks
The following are procedures for checking fluids leak, lubricates leak and exhaust gases leak.
 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 LU-15, "
Inspection", CO-35, "Inspection".
 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 gases, or any oil/fluids includ-
ing engine oil and engine coolant.
 Bleed air from lines and hoses of applicable lines, such as in cooling system.
 After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to the
specified level, if necessary.
