Oil Pan Removal and Installation

Oil Pan: Removal and Installation

Removal

WARNING:

To avoid the danger of being scalded, do not drain engine oil when engine is hot.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

1) Remove engine under cover. Refer to [Front Bumper: Removal and Installation] Service and Repair.
2) Drain engine oil. Refer to [Changing Engine Oil] Service and Repair.

CAUTION:
- Perform this step when the engine is cold.
- Do not spill engine oil on drive belt.

3) Remove 3rd crossmember assembly.
4) Remove lower joint shaft pinch bolt at steering gear. Refer to [Steering Column: Removal and Installation] Removal and Replacement.
5) Remove steering gear bolts. Refer to [Power Steering Gear and Linkage: Removal and Installation] Removal and Replacement.
6) Remove oil pan with the following procedure:
a) Loosen bolts in reverse order as shown with power tool. Remove A/T fluid cooler tube bracket (A/T models).





b) Insert Tool between the oil pan and the cylinder block and remove oil pan.











CAUTION:
- Be careful not to damage the mating surfaces.
- Do not insert a screwdriver, this will damage the mating surfaces.

NOTE:
Tap (1) Tool to insert it and then slide (2) it by tapping on the side of the Tool as shown.

Inspection after Removal

Clean oil strainer if any object attached.

Installation

1) Install oil pan with the following procedure:
a) Use a scraper to remove old liquid gasket from mating surfaces.





- Also remove the old liquid gasket from mating surface of 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.

b) Apply a continuous bead of liquid gasket using Tool as shown.










Use Genuine RTV Silicone Sealant or equivalent. Refer to [Recommended Chemical Products and Sealants] Recommended Chemical Products and Sealants.

CAUTION:
Attaching should be done within 5 minutes after coating.

c) Tighten bolts in numerical order as shown.





- Install A/T fluid cooler tube bracket with bolts No.1 and 9 as shown (A/T models).
2) Install oil pan drain plug. Refer to [Changing Engine Oil] Service and Repair.
3) Installation is in the reverse order of removal after this step.

NOTE:
Pour engine oil at least 30 minutes after oil pan is installed.

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 [Recommended Fluids and Lubricants [for USA and Canada] [1][2]Maintenance ] (United States and Canada) or [Recommended Fluids and Lubricants [for Mexico] ] (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.
