Solution

1. Preparation

• Gather tools and components.
• Safety equipment: gloves, goggles, and a floor jack if necessary.
• Ensure the engine is cool before starting work.

2. Identify and Remove Leaking Component

• Radiator Hoses:

  1. Use pliers to loosen the hose clamps.
  2. Remove the hoses from the radiator and engine.
  3. Inspect for cracks or damage.

• Replace if damaged:

  1. Install new hoses, ensuring proper alignment.
  2. Tighten hose clamps to manufacturer specifications.

• Radiator:

  1. Drain coolant from the radiator by opening the drain valve.
  2. Disconnect the transmission cooler lines (if equipped) and hoses.
  3. Unscrew mounting brackets and remove the radiator.
  4. Inspect for leaks; replace if necessary.

• Water Pump:

  1. Drain coolant from the system.
  2. Remove the drive belt by loosening the tensioner.
  3. Unscrew the water pump from the engine block.
  4. Clean the mounting surface and install a new water pump with a new gasket.
  5. Reassemble and replace coolant.

3. Refill and Bleed Cooling System

1. Refill the coolant reservoir with the appropriate coolant type and mixture.
2. Start the engine and let it reach operating temperature.
3. Open the bleed valve (if equipped) to remove air from the system until coolant flows out.
4. Close the bleed valve and check for leaks around the repaired areas.
