Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool to prevent burns.
Disconnect the battery to avoid any electrical issues.

2. Locate and Repair Leaks

Coolant Reservoir:
- Remove the reservoir by disconnecting the hoses and mounting bolts.
- Inspect for cracks; replace if necessary.
Hoses:
- Inspect each hose for cracks or soft spots.
- Replace any damaged hoses with OEM parts.
Radiator:
- Remove the radiator by disconnecting the upper and lower hoses and any mounting brackets.
- Inspect for leaks; replace if necessary.

3. Water Pump Inspection

Remove the serpentine belt by releasing tension from the tensioner.
Unbolt the water pump from the engine block and remove it.
Inspect the water pump gasket and impeller for damage; replace if necessary.

4. Refill and Bleed Cooling System

Reinstall all components securely.
Fill the coolant reservoir with the appropriate type of coolant (refer to owner’s manual for specifications).
Start the engine with the radiator cap off, allowing air bubbles to escape until the coolant level stabilizes.
Replace the radiator cap securely once air is purged.
