10. Install camshaft sprocket (EXH) (2).
NOTE:
Secure the hexagonal part (A) of camshaft (EXH) using wrench
to tighten bolt.
11. Install timing chain and related parts. Refer to EM-160 .
12. Inspect and adjust valve clearance. Refer to EM-178, " Valve Clearance " .
13. Installation of the remaining components is in the reverse order of removal.
INSPECTION AFTER INSTALLATION The following are procedures for chec king fluids leak, lubricates leak.
• Before starting engine, check oil/fluid levels incl uding engine coolant and engine oil. If less than required
quantity, fill to the specified level. Refer to GI-42, " Recommended Chemical Product and Sealant " .
• 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/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 leak age of fuel, or any oil/fluids including 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.
Summary of the inspection items:
* Transmission/transaxle/CVT fluid, power steering fluid, brake fluid, etc.
Inspection of Camshaft Sprocket (INT) Oil Groove
CAUTION:
• Perform this inspection only when DTC P0011 is detected in self-diagnostic results of CONSULT-III
and it is directed according to inspect ion procedure of EC section. Refer to EC-638, " Diagnosis Pro-
cedure " (Type 1) or
EC-1153, " Diagnosis Procedure " (Type 2).
• Check when engine is cold so as to pr event burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-16, " Inspection " .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while checking.
a. Remove intake manifold. Refer to EM-141, " Component " .
