Removal and Installation

REMOVAL

WARNING:

• Be careful not to get burned, engine coolant and engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer; avoid direct skin contact with used oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as possible.

1. Drain engine oil.
2. Loosen bolts in reverse order as shown.

: Engine front

3. Insert Tool (A) between oil pan (upper) and oil pan (lower).

Tool number : KV10111100 (J37228)

CAUTION:

• Do not damage mating surfaces.
• Do not insert a screwdriver. This damages the mating surfaces.

4. Slide the Tool (A) by tapping on the side of tool with a suitable tool to loosen the oil pan (lower).
5. Remove oil pan (lower).

INSPECTION AFTER REMOVAL

Clean debris from oil pan (lower) and from the strainer.

INSTALLATION

CAUTION:

Do not reuse Orings or washers.

1. Use a scraper (A) to remove old liquid gasket from mating surfaces.

• Also remove old liquid gasket from mating surface of oil pan (upper).
• Remove old liquid gasket from the bolt holes and threads.

CAUTION:

Do not scratch or damage the mating surface when cleaning off old liquid gasket.

2. Apply a continuous bead of liquid gasket (A) with a tube presser as shown.

(1) : Oil pan (lower)

(a) : 7.5 9.5 mm (0.295 0.374 in)

(b) : 4.0 5.0 mm (0.157 0.197 in) diameter

 : Engine outside

Use Genuine Silicone RTV Sealant or equivalent.

CAUTION:

• The components must be installed within 5 minutes of the liquid gasket application.
• Do not confirm torque after the 5 minutes have elapsed.
• Then allow 30 minutes for the liquid gasket to set before adding oil to the engine.

3. Tighten bolts in numerical order as shown.

 : Engine front

4. Install oil pan drain plug.

• Refer to the figure for installation direction of drain plug washer.

CAUTION:

• Installation should be done within 5 minutes after applying liquid gasket.
• Do not fill the engine with oil for at least 30 minutes after the oil pan (lower) is installed to allow the sealant to cure.

5. Add the specified oil after waiting for at least 30 minutes.

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.
• 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:
