Replace any damaged hoses or the radiator as necessary.
Refill the cooling system with the appropriate coolant mix (50/50 distilled water and coolant).
Bleed the cooling system to remove air pockets.

4. Inspect Belts and Hoses

Visually inspect serpentine belt for cracks or fraying; replace if needed.
Check all hoses for signs of wear; replace any that are damaged or leaking.

5. Exhaust System Inspection

Inspect exhaust manifold and pipes for cracks or leaks.
Tighten any loose connections and replace gaskets as necessary.

6. Reconnect Battery and Test
