Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is turned off and cool.
Disconnect the battery to prevent any electrical shorts.

2. Change Oil and Filter

Sub-steps:
1. Remove the oil drain plug using a socket wrench and allow the old oil to drain into a container.
2. Replace the oil filter—use an oil filter wrench to remove it, then lubricate the rubber seal on the new filter and install it.
3. Reinstall the drain plug and torque it to the manufacturer’s specifications (typically 25 Nm).
4. Fill the engine with new oil (5W-40 or as specified in the owner’s manual) through the oil filler cap, using the correct amount (approximately 5 quarts).
Tools Required: Socket set, oil filter wrench, torque wrench.
Safety Warnings: Allow engine to cool before opening the drain plug. Dispose of old oil and filter properly.

3. Inspect Oil Pump

Sub-steps:
1. Remove the oil pump access cover (if applicable) and inspect for wear or damage.
2. Check the oil pump drive shaft for proper engagement.
3. If defective, replace the oil pump by removing the necessary components to access it, following manufacturer guidelines for specific torque values during reassembly.
Tools Required: Socket set, screwdrivers, torque wrench.

4. Check for Leaks

Sub-steps:
1. Inspect all oil seals and gaskets for signs of wear or leakage.
2. Replace any damaged seals or gaskets.
3. Clean the oil pan and surrounding areas to remove any residual oil, then recheck after running the engine for new leaks.
Tools Required: Gasket scraper, sealant, socket set.
