Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and secured with wheel chocks.
Disconnect the battery to avoid accidental electrical issues.

2. Change Oil and Filter

Tools Required: Socket set, oil filter wrench, drain pan, funnel.
Instructions:
1. Place the drain pan under the oil pan.
2. Remove the oil drain plug and allow the old oil to completely drain.
3. Replace the drain plug and tighten it to the manufacturer's torque specification (typically around 20-30 lb-ft).
4. Remove the old oil filter using an oil filter wrench.
5. Apply a thin layer of new oil to the rubber gasket of the new oil filter.
6. Install the new oil filter and tighten it according to the manufacturer’s specifications.
7. Fill the engine with the recommended oil type and quantity (check the owner’s manual for specifications).

3. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper.
Instructions:
1. Remove the oil pan by unbolting it from the engine block and carefully scraping off the old gasket.
2. Inspect the oil pump for wear or damage.
3. If the oil pump is faulty, remove it from the engine and install a new one, ensuring proper alignment.
4. Reinstall the oil pan with a new gasket, torquing the bolts to the manufacturer's specifications.
