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.
