Solution

1. Preparation

Gather necessary tools and parts.
Safety gear: gloves and safety glasses.
Ensure the engine is cool before starting.

2. Locate the Coolant Leak

Sub-steps:
- Inspect the coolant reservoir for cracks or leaks.
- Check the hoses connected to the radiator and engine for any visible damage.
- Look for wet spots around the water pump and radiator.

3. Repair or Replace Damaged Components

Sub-steps:
- If the coolant reservoir is damaged, remove it by unscrewing bolts and disconnecting the hose.
- Replace with a new coolant reservoir if necessary.
- For faulty hoses, remove the affected hose clamps and replace the hose with a new one, ensuring a tight fit.
- Inspect and replace the radiator cap if it is not sealing properly.

4. Refill Coolant

Sub-steps:
- Use a mixture of 50% coolant and 50% distilled water unless specified otherwise by the manufacturer.
- Fill the coolant reservoir to the appropriate level.
- Start the engine and let it idle for a few minutes, allowing the thermostat to open and circulate the coolant.
- Check for leaks once the engine is warmed up.

5. Final Check

Sub-steps:
- After the engine cools down, recheck the coolant levels in both the reservoir and radiator.
- Top off if necessary.
- Dispose of any spilled coolant properly, as it is toxic.
