Solution

1. Preparation

Tools Required: Gloves, safety goggles, funnel, and coolant.
Ensure the engine is cool before proceeding.
Park the vehicle on a level surface and engage the parking brake.

2. Check Coolant Level

Open the hood and locate the coolant reservoir.
Remove the cap carefully to avoid pressure release.
Check the coolant level against the "Full" and "Low" markings on the reservoir.

3. Add Coolant

If the level is low, use a funnel to add the appropriate coolant type (usually a 50/50 mix of coolant and distilled water).
Fill to the "Full" line on the reservoir.
Replace the cap securely.

4. Inspect for Leaks

Start the engine and let it idle while checking for leaks around the hoses, radiator, and water pump.
Look for any signs of coolant dripping or pooling under the vehicle.
If leaks are found, identify the source for further repair.

5. Replace Damaged Components (if needed)

If any hoses or the radiator are damaged, use the following steps:
- Remove the damaged hose/radiator: Disconnect clamps and remove.
- Install the new component: Position the new part and secure it with clamps.
- Re-fill the coolant: After replacement, repeat step 3.
