Solution

1. Preparation

Gather tools and parts required for maintenance.
Park the vehicle on a level surface and engage the parking brake.
Ensure the engine is cool before starting work.

2. Tire Maintenance

Check Tire Pressure:
- Use a tire pressure gauge to measure the pressure in each tire.
- Inflate tires to the manufacturer-recommended pressure (found on the driver’s side door jamb).
Inspect Tires for Wear:
- Check tread depth using the penny test; replace tires if tread is worn below the recommended level.

3. Air Filter Replacement

Locate and Remove Air Filter:
- Open the hood and locate the air intake housing.
- Unscrew or unclip the housing cover and remove the old air filter.
Install New Air Filter:
- Insert a new air filter that meets OEM specifications.
- Reassemble the air intake housing securely.

4. Fuel System Inspection

Inspect Fuel Injectors:
- Use a fuel injector cleaner to clean the injectors if they are clogged.
- Consider replacing injectors if cleaning does not improve performance.
Check Fuel Pump:
- Listen for the fuel pump operation when turning the ignition to the “on” position.
- If the pump is noisy or not functioning, replacement may be necessary.

5. Oil Change

Drain Old Engine Oil:
- Place an oil drain pan under the oil pan.
- Remove the oil drain plug and allow the oil to drain completely.
Replace Oil Filter:
- Remove the old oil filter using an oil filter wrench.
- Apply a thin layer of oil to the rubber gasket of the new filter and install it.
Add New Engine Oil:
- Replace the drain plug and refill the engine with the recommended type and amount of engine oil.
