Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative battery terminal to ensure safety.

2. Check and Change Oil and Filter

Locate the oil drain plug and place a drain pan underneath.
Remove the drain plug using a socket wrench and allow the old oil to fully drain.
Replace the drain plug and torque it to the manufacturer’s specifications (usually around 25-30 ft-lbs).
Remove the old oil filter using an oil filter wrench; ensure the rubber O-ring comes off with it.
Lubricate the rubber O-ring on the new oil filter with new oil and install it, tightening by hand.
Fill the engine with new oil (SAE 0W-20 recommended) through the oil filler cap, using the amount specified in the owner’s manual (typically around 4.5 quarts).

3. Inspect and Replace Oil Pump (if necessary)

If low oil pressure persists, remove the oil pan by unbolting it; ensure to remove any necessary undercarriage components for access.
Inspect the oil pump for any visible damage or wear.
If replacement is needed, disconnect the oil pump from the engine block and install the new oil pump following manufacturer instructions.
Reinstall the oil pan and torque the bolts to manufacturer specifications.
