Solution

1. Preparation

Gather tools and parts.
Ensure the engine is cool and disconnect the battery.
Place a drain pan under the vehicle to collect any leaking coolant.

2. Locate and Repair the Leak

Coolant Reservoir:
- Remove the reservoir cap.
- Inspect for cracks; if damaged, replace with a new reservoir.
Hoses:
- Loosen hose clamps and remove hoses.
- Inspect for cracks; replace any damaged hoses.
- Reattach hoses securely and tighten clamps.
Radiator:
- Check for visible leaks; if damaged, replace the radiator.
Water Pump:
- Remove any components obstructing access (i.e., serpentine belt).
- Inspect the water pump for leaks.
- If leaking, remove the old pump and install a new one using a gasket or sealant as necessary. Torque the bolts to the manufacturer's specifications.

3. Replace Coolant

Drain old coolant from the system.
Refill with the appropriate type and mixture of coolant as per the vehicle's specifications.
Bleed the cooling system to remove air pockets.

4. Final Assembly

Reinstall any components removed during the repair.
Reconnect the battery.
Start the engine and check for leaks.
