Solution

1. Preparation

Gather necessary tools and ensure the engine is cool to prevent burns.
Disconnect the battery to avoid electrical hazards.

2. Inspect and Repair Leaks

Coolant Reservoir:
- Remove the coolant reservoir cap and inspect for cracks.
- Replace the reservoir if damaged.
Hoses and Clamps:
- Visually inspect all coolant hoses for wear or leaks.
- Tighten or replace any loose or damaged hoses and clamps.
Radiator:
- Check the radiator for signs of leaks or corrosion.
- Replace the radiator if it is leaking.
Water Pump:
- Inspect the water pump for leaks around the shaft seal.
- Replace the water pump if any leaks are detected.
Heater Core:
- Check the heater core for signs of leaks.
- If leaking, replace the heater core, which may require removing the dashboard.

3. Refill and Bleed the Cooling System

Refill Coolant:
- Use the manufacturer-recommended coolant type.
- Fill the coolant reservoir to the recommended level.
Bleed the System:
- Start the engine and let it reach operating temperature.
- Open the bleed screw (if applicable) to release trapped air until coolant flows steadily.
