Solution

1. Preparation

Gather tools and parts needed.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the battery to avoid electrical issues.

2. Change Engine Oil and Filter

Drain Old Oil
- Place an oil catch pan under the oil pan.
- Remove the oil drain plug using a socket wrench and allow oil to drain completely.
- Replace the drain plug and torque to the manufacturer's specification (typically 20-25 ft-lbs).
Replace Oil Filter
- Locate the oil filter and use an oil filter wrench to remove it.
- Apply a small amount of clean oil to the rubber gasket of the new oil filter.
- Install the new oil filter by hand until snug, then tighten according to specifications (usually 3/4 turn after the gasket makes contact).
Add New Oil
- Remove the oil filler cap and pour in the new engine oil (ensure it meets the manufacturer’s specifications, usually 5W-30).
- Replace the oil filler cap.

3. Inspect Oil Pump and Components

Remove Oil Pan
- Support the vehicle securely on jack stands.
- Remove any components obstructing access to the oil pan (e.g., exhaust components).
- Unbolt and remove the oil pan.
Inspect the Oil Pump
- Check the oil pump for signs of wear or damage.
- If necessary, replace the oil pump following manufacturer specifications.

4. Reassemble and Refill

Reinstall the oil pan with a new gasket, torquing the bolts to the manufacturer’s specifications.
Reinstall any components removed earlier.
Reconnect the battery.
