TIMING CHAIN
 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 check 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.

ENGINE ASSEMBLY
 Place chocks at front and back of rear wheels.
 For engines not equipped with engine slingers, attach proper slingers and bolts described in PARTS
CATALOG.
CAUTION:
 Always be careful to work safely, avoid forceful or uninstructed operations.
 Never start working until exhaust system and engine coolant are cool enough.
 If items or work required are not covered by the engine section, refer to the applicable sections.

INSPECTION AFTER INSTALLATION
Inspection for Leakage
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 MA-11, "
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.

WARNING:
Be careful not to touch rotating parts. (drive belt, idler pul-
ley, and crankshaft pulley, etc.)
CAUTION:
 Prevent splashing by using a shop cloth so as to prevent
the worker from injury from engine oil and so as to prevent engine oil contamination.
 Prevent splashing by using a shop cloth so as to prevent engine oil from being splashed to
engine and vehicle. Especially, be careful no to apply engine oil to rubber parts of drive belt,
engine mounting insulator, etc. Wipe engine oil off immediately if it is splashed.
