Loosen and remove the clamps from the leaky hoses.
Replace with new hoses, ensuring they are the correct length and size.
Reattach clamps securely.

3. Repair or Replace Radiator

Tools Required: Socket set, screwdriver, coolant drain pan
Remove the front grill if necessary for access.
Disconnect the upper and lower radiator hoses.
Unbolt the radiator from the mounting points and remove it.
Inspect for any cracks or leaks; replace if necessary.
Install the new radiator by reversing the removal steps.

4. Replace Water Pump (if necessary)

Tools Required: Socket set, torque wrench, gasket scraper
Disconnect the necessary hoses and wiring from the water pump.
