TIMING CHAIN

Check for cracks and any excessive wear at link plates and roller
links of timing chain. Replace timing chain as necessary.

INSPECTION AFTER INSTALLATION

Inspection for Leaks

• 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-21, "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 chain tensioner drops after removal/installation, slack in guide may generate a
pounding noise during and just after the engine start. However, this does not indicate an unusualness. 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.
