INSPECTION AFTER REMOVAL

Clean oil strainer if any object is attached.

INSTALLATION

1.Install oil strainer and tighten bolt to specified torque. Exploded View.





2.Apply Genuine Silicone RTV Sealant or equivalent, to the front cover gasket and the rear oil seal retainer gasket as shown.
Recommended Chemical Products And Sealants.
Tool number: WS39930000 (-)

CAUTION:
The components must be installed within 5 minutes of the liquid gasket application. Then allow 30 minutes for the liquid gasket to set before operating the engine.





3.Install the front cover gasket and rear oil seal retainer gasket as shown.

CAUTION:
Do not reuse gaskets.





4.Apply a bead of sealant to the cylinder block mating surface of the upper oil pan to a limited portion as shown.
- Use Genuine Silicone RTV Sealant, or equivalent. Recommended Chemical Products And Sealants.
- Be sure the sealant is applied to a limited portion as shown, and the sealant is 4.0 - 5.0 mm (0.157 - 0.197 in) or 4.5 - 5.5 mm (0.177 - 0.217 in) wide.

5.Install new O-rings on the cylinder block and oil pump body.

CAUTION:
Do not reuse O-rings.





6.Install the upper oil pan.
- Tighten upper oil pan bolts in the order as shown.
- Wait at least 30 minutes before refilling the engine with oil.
7.Install the lower oil pan. Lower Oil Pan.
8.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. Recommended Chemical Products And Sealants (United
States and Canada) or Recommended Chemical Products And Sealants (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.
