Solution

1. Preparation

Tools Required:
- Safety goggles
- Gloves
- Coolant catch basin
Ensure the engine is cool before starting work to prevent burns.

2. Remove Components for Access

Disconnect the battery to avoid any electrical issues.
Remove any engine covers that obstruct access to the cooling system.
Detach the air intake assembly if it blocks access to hoses and the radiator.

3. Inspect and Repair Leaks

Radiator and Hoses:
- Inspect the radiator for cracks or corrosion.
- Check all hoses for bulges, cracks, or loose connections.
- Replace any damaged hoses or the radiator if necessary.
Water Pump:
- Inspect the water pump for leaks around the seal.
- If leaking, remove the water pump and replace with a new unit, ensuring to replace the gasket.

4. Refill and Bleed Cooling System

Reattach all components removed earlier.
Fill the coolant reservoir with the appropriate type of coolant specified in the owner's manual.
Bleed the cooling system to remove any air pockets by running the engine with the radiator cap off until the thermostat opens, then topping off the coolant.

5. Final Check

Reconnect the battery and start the engine.
Allow the engine to reach operating temperature, and monitor for leaks.
Check the coolant level again and top off if necessary.
