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-15, "FOR USA AND CANADA : Fluids and
Lubricants" (United States and Canada) or MA-16, "FOR MEXICO : Fluids and
Lubricants" (Mexico).
- 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 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 specified level, if necessary.
- Summary of the inspection items:
*Power steering fluid, brake fluid, etc.
