5. Using a rubber-faced hammer, tap the oil pan, then remove the pan (upper and lower parts).

Examination

Checking the oil filter seat

1. Check that there is no damage to the contact surface of the oil filter.

2. Check for cracks or oil leaks.

Oil pan and oil pickup

1. Check the oil pan for deformation, damage or cracks. Replace if defective.

2. Check the oil intake for deformation, damage or cracks. Replace if defective.

Installation

1. Installing the oil pan.

a) Remove the remains of the old gasket from the oil pan flange and the cylinder block mating surface. After cleaning, degrease the surfaces to apply the sealant.

Note: Before applying sealant, make sure the oil pan flange and the mating surface of the cylinder block are dry and clean.

b) Apply a continuous bead of sealant approximately 4 mm in diameter around the entire flange of the upper and lower parts of the oil pan as shown in the figure.

Sealant:

2.0L/2.4L Engines: Three Bond 1104 or equivalent
2.7L Engine: Three Bond 1141E, ЗМ ATD #8660 or equivalent

Attention:

To prevent oil leaks, apply sealant to the bolt holes on the cylinder block.

Install and secure the oil pan within 15 minutes after applying the sealant.

Apply the specified amount of sealant so that when tightening the pan, the sealant is not squeezed out beyond the flange.

After assembly, wait at least 30 minutes before adding engine oil to the engine.

Engines 2.0 l / 2.4 l.

Engines 2.7 l.

c) Install the oil pan (upper and lower parts) and tighten its mounting bolts to the specified torque.

Please note: The oil pan mounting bolts installed in the indicated locations are of different lengths.
