Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool; disconnect the battery for safety.
Collect coolant and a container for draining old coolant.

2. Identify and Repair Leaks

Coolant Reservoir and Radiator:
- Remove the coolant reservoir cap and inspect for cracks.
- If damaged, replace with a new coolant reservoir.
Hoses:
- Inspect each hose for signs of wear or leaks.
- Replace any damaged hoses with new ones.
Water Pump:
- If the water pump is leaking, remove the drive belt.
- Unbolt the water pump and replace it with a new unit.
- Torque the bolts to the manufacturer's specifications.

3. Head Gasket and Engine Block Inspection

If leaks are suspected from the engine block or head gasket, follow these steps:
- Remove necessary components to access the head gasket.
- Conduct a compression test to check for head gasket failure.
- Replace the head gasket if necessary, ensuring to torque to manufacturer specifications.

4. Fill and Bleed Cooling System

Refill the coolant reservoir with the appropriate coolant mixture.
Start the engine with the radiator cap off, allowing air to escape.
Once the engine reaches operating temperature and air bubbles stop, replace the cap.
