INSPECTION AFTER INSTALLATION
The following are procedures for checking fluids leak, lubricates 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 GI-46, "
Recommended Chemical Products and Sealants" .

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
leakage 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 leakage 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-II
and it is directed according to inspection procedure of EC section. Refer to EC-47, "
ON BOARD
DIAGNOSTIC (OBD) SYSTEM" .

Check when engine is cold so as to prevent burns from the splashing engine oil.
1. Check engine oil level. Refer to LU-5, "
ENGINE OIL LEVEL" .
2. Perform the following procedure so as to prevent the engine from being unintentionally started while
checking.
a. Remove intake manifold. Refer to EM-18, "
