- Inspect hoses for cracks or wear; replace any damaged hoses.
- Reattach hoses securely with clamps and check for tightness.

3. Repair or Replace the Radiator

Sub-steps:
- If leaks are found in the radiator, remove it by unbolting it from its mounts and disconnecting the inlet and outlet hoses.
- Inspect the radiator for any cracks or corrosion. If damaged, replace it with a new unit.
- Install the new radiator by reversing the removal steps and ensure all connections are secure.

4. Replace the Water Pump (if necessary)

Sub-steps:
- If the water pump is leaking, drain the coolant from the system.
- Remove the serpentine belt from the water pump by loosening the tensioner.
- Unbolt the water pump from the engine and remove it.
- Clean the mounting surface on the engine and install a new gasket with the new water pump.
- Reattach the water pump and serpentine belt.

5. Refill and Bleed the Cooling System

Sub-steps:
- Refill the coolant reservoir with the appropriate type of coolant (refer to owner's manual for specifications).
- Start the engine and allow it to reach operating temperature while monitoring coolant levels.
- Open the bleed valve (if equipped) to release air pockets and top off coolant as necessary.
