- Reconnect any electrical connectors and the fuel line.
9. Add Fluids and Test:
- Add new engine oil to the engine.
- Add new engine coolant to the radiator.
- Reconnect the battery.
- Start the engine and let it run idle for a few minutes. Check for any leaks or unusual sounds.
10. Check Fluids and Test Drive:
- Allow the engine to reach normal operating temperature and inspect for coolant leaks.
- Check the engine oil for any signs of contamination.
- Take the vehicle for a test drive to ensure proper performance.
