REAR TIMING CHAIN CASE
g. After installing rear timing chain case, check the surface height
difference between following parts on oil pan (upper) mounting
surface.
• If not within the standard, repeat the installation procedure.
2. Install water pump with new O-rings, if removed. Refer to CO-21, "Removal and Installation"
.
CAUTION:
Do not reuse O-rings.
3. Install timing chains and related components. Refer to EM-59, "Removal and Installation"
and EM-68,
"Removal and Installation (Secondary Timing Chain Tensioner)".
4. Install front timing chain case. Refer to EM-51, "Removal and Installation"
.
5. Install oil pan (upper) and (lower). Refer to EM-34, "Removal and Installation"
.
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 MA-13, "Fluids and Lubricants"
.
• 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.
NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide
may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop
after hydraulic pressure rises.
• 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 oil/fluid levels including engine oil and engine coolant. Refill to spec-
ified level, if necessary.
• Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
