- Remove the clamps using a screwdriver or pliers.
- Cut the old hose and replace it with a new one of the correct size.
- Re-secure the clamps.

3. Repair or Replace the Radiator

Remove the Radiator:
- Unscrew the mounting bolts securing the radiator.
- Disconnect the inlet and outlet hoses.
- Carefully lift out the radiator.
Inspect for damage:
- Look for signs of corrosion, cracks, or leaks.
If damaged, replace with a new radiator:
- Install the new radiator and reconnect the hoses.
