 INSPECTION AFTER ASSEMBLY
 
 Inspection for Leakage


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 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 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 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.
