If the leak is small and repairable, use a radiator sealant as per the manufacturer's instructions.
For larger cracks, consider replacing the radiator entirely.

5. Install New or Repaired Radiator

Place the radiator back into position in the engine bay.
Secure the radiator with mounting bolts or brackets.
Reconnect the upper and lower radiator hoses, ensuring they are tight and leak-free.

6. Refill Coolant

Use the manufacturer-recommended coolant type and mix.
Fill the radiator and reservoir to the appropriate levels.
Replace the radiator cap securely.
