1. Preparation

Tools Required: Jack and jack stands, oil catch pan, socket set, torque wrench, rags, UV light (if using dye).
Ensure the vehicle is on a flat surface and the engine is cool.
Disconnect the battery before starting work on electrical connections.

2. Locate the Source of the Leak

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Clean the engine area around suspected leak points with a degreaser.
3. Start the engine and visually inspect for leaks, using a UV light if necessary.

1. If the oil filter is leaking, replace it with a new filter. Ensure to lubricate the rubber O-ring on the new filter.
2. If the oil drain plug is leaking, remove it, clean the threads, and replace the washer if needed before re-installing and tightening to the manufacturer's torque specifications (typically around 20-25 Nm).
3. If the oil pan gasket is damaged, remove the oil pan, replace the gasket, and reassemble, ensuring to torque bolts to the specified values (usually around 10-15 Nm).

4. Refill Engine Oil

Sub-steps:
