Solution

1. Preparation

Gather tools and parts required for the repair.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Disconnect the battery to ensure safety while working.

2. Change Engine Oil and Filter

Tools Required: Socket set, oil filter wrench, drain pan, funnel
Sub-steps:
1. Place the drain pan under the oil pan.
2. Remove the oil drain plug using a socket and allow the old oil to drain completely.
3. Remove the old oil filter with an oil filter wrench.
4. Lubricate the rubber O-ring of the new oil filter with a small amount of new oil.
5. Install the new oil filter by hand and tighten it according to the manufacturer's specifications.
6. Reinstall the drain plug and tighten it to the specified torque (typically around 25 ft-lbs).
7. Refill the engine with new oil (consult the owner’s manual for the correct type and capacity, usually 6-7 quarts of 0W-20 or 5W-20).

3. Inspect and Replace Oil Pump (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper, new oil pump
Sub-steps:
1. Remove any components obstructing access to the oil pump (e.g., timing cover).
2. Disconnect the oil pump from the engine by removing the mounting bolts.
3. Inspect the old oil pump for wear or damage.
4. Clean the mating surface on the engine block and remove any old gasket material.
5. Install the new oil pump with a new gasket and torque the bolts to manufacturer specifications.
6. Reassemble any components removed for access.
