Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the battery for safety.

2. Drain Oil

Tools Required: Socket set, oil drain pan
Place the oil drain pan under the oil pan.
Remove the oil drain plug using the socket set, allowing the old oil to completely drain out.
Replace the drain plug and tighten to the manufacturer’s specified torque (typically around 15-20 ft-lbs).

3. Replace Oil Filter

Tools Required: Oil filter wrench
Use the oil filter wrench to remove the old oil filter.
Apply a thin layer of new oil to the rubber O-ring of the new oil filter.
Install the new oil filter, hand-tightening it.

4. Inspect and Replace Seals and Gaskets

If leaks are found at the oil pan, valve cover, or crankshaft seals, replace them:
- Tools Required: Socket set, gasket scraper, RTV sealant (if required)
- Remove the components covering the gasket or seal (e.g., intake manifold for valve cover gasket).
- Scrape off any old gasket material and clean the mating surfaces.
- Apply the new gasket or sealant as required and reassemble the components.

5. Refill Engine Oil

Tools Required: Funnel
Pour the appropriate type and amount of new engine oil (consult owner’s manual) into the engine using a funnel.
Start the engine and let it run for a few minutes, then check for leaks.
