Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to prevent any electrical shorts.
Allow the engine to cool down before starting work.

2. Inspect and Replace Oil

Inspect Engine Oil:
- Remove the oil dipstick and check the oil for discoloration or burnt smell.
Change Oil if Necessary:
- Use a socket set to remove the oil drain plug.
- Drain the old oil into a suitable container.
- Replace the oil filter using an oil filter wrench.
- Reinstall the drain plug and torque to manufacturer specifications (typically 30 lb-ft).
- Fill with the correct type of oil (5W-20 is common for this model).

3. Address Coolant Issues

Inspect Coolant System:
- Check the coolant reservoir and radiator for leaks.
- Use a coolant pressure tester if needed.
Replace Coolant if Leaking:
- Drain the old coolant and refill with the proper mixture (50/50 coolant and distilled water).
- Check for proper operation of the thermostat and radiator.

4. Examine Exhaust System

Inspect for Leaks:
- Visually inspect the exhaust system for holes, cracks, or loose connections.
Repair or Replace Components:
- Use a wrench to tighten loose connections or replace damaged sections with new exhaust parts as needed.

5. Check Fuel System

Inspect Fuel Lines:
- Look for cracks or leaks in fuel lines and connections.
Replace Faulty Components:
- Replace any damaged fuel injectors or lines, ensuring all seals are tight.
