Solution

1. Preparation

Tools Required: Socket set, torque wrench, oil catch pan, rags, and cleaning solvent.
Park the vehicle on a level surface and allow the engine to cool.
Disconnect the negative battery terminal to ensure safety.

2. Drain Engine Oil

Place an oil catch pan under the oil pan.
Remove the oil drain plug using a socket wrench and allow the oil to fully drain.
Replace the drain plug and tighten it to the manufacturer's specified torque (usually around 25 Nm).

3. Remove the Oil Pan

Using a socket wrench, remove all bolts securing the oil pan to the engine block.
Gently tap the oil pan with a rubber mallet if it is stuck, then carefully lower the pan and remove it from the vehicle.

4. Clean the Surface

Clean the mating surfaces of the oil pan and engine block using a scrapper and cleaning solvent to remove old gasket material and oil residue.
Ensure no debris falls into the engine.

5. Install New Gasket

Place a new oil pan gasket onto the oil pan, ensuring proper alignment.
If using gasket sealant, apply a thin bead as recommended by the manufacturer.

6. Reinstall the Oil Pan

Position the oil pan back onto the engine block.
Hand-tighten the bolts, then use a torque wrench to tighten them to the specified torque settings, usually in a crisscross pattern to ensure even pressure.

7. Refill Engine Oil

Fill the engine with the correct type and amount of engine oil as specified in the owner's manual.
Reconnect the negative battery terminal.
