      • Also remove the old liquid gasket from mating surface of lower cylinder block.
      • Remove old liquid gasket from the bolt holes and threads.
      CAUTION: Do not scratch or damage the mating surfaces when cleaning off old liquid gasket.
   2. Install new O-rings on the bottom of lower cylinder block and oil pump.

      CAUTION:

      • Remove water, oil, dust, dirt, or other foreign material on all sealing surfaces prior to installation.
      • For bolt holes with mark, apply liquid gasket outside the hole.
      • Apply a bead of 4.5 to 5.5 mm (0.177 to 0.217 in) in diameter to area (A).
      • Attaching should be done within 5 minutes after coating.
      • The components must be installed within 5 minutes of the liquid gasket application. Then allow 30 minutes for the liquid gasket to set before refilling the engine oil.
      • Use Genuine RTV Silicone Sealant or equivalent. Refer to Recommended Chemical Products and Sealants .
   4. Install oil pan (upper).
      CAUTION:

      • Do not reuse O-rings.
      • Install avoiding misalignment of both oil pan gaskets and O-rings.
      • Tighten oil pan (upper) bolts in numerical order as shown.

      • There are two types of bolts.

        M8 x 100 mm (3.97 in)	: 7, 11, 12, 13
        M8 x 25 mm (0.98 in)	: All except the above

   5. Tighten transmission joint bolts.
2. Install oil strainer to oil pan (upper).
3. Install oil pan lower. Refer to OIL PAN LOWER.
4. Installation of the remaining components is in the reverse order of removal.

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 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 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:
