Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery before starting any electrical work.
Ensure the vehicle is on a flat surface and securely lifted if necessary.

2. Addressing Overheating

Check the coolant level and top off if low.
Inspect hoses and radiator for leaks or damage.
Replace the thermostat if it is stuck closed.
- Sub-steps:
  - Drain coolant.
  - Remove the thermostat housing.
  - Install the new thermostat and reassemble.
Refill coolant and bleed the system of air.

3. Fuel System Inspection

Inspect the fuel filter for clogs and replace if necessary.
- Tools required:
  - Fuel line disconnect tool
- Sub-steps:
  - Relieve fuel system pressure.
  - Disconnect the fuel lines.
  - Replace the fuel filter.
Test the fuel pump for adequate pressure with a fuel pressure gauge.
- Replace the fuel pump if pressure is low.

4. Electrical System Check

Test the battery with a multimeter to ensure it has a charge above 12.6 volts.
Check the alternator output; it should be between 13.5V to 14.5V while the engine is running.
Replace the battery or alternator if readings are outside of the specified range.

5. Ignition System Maintenance

Remove and inspect spark plugs for wear or fouling; replace if needed.
Check ignition coils for proper operation.
