Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool and park the vehicle on a level surface.
Disconnect the battery for safety.

2. Locate the Leak

Use a pressure tester on the cooling system to pinpoint the leak.
Visually inspect all components (reservoir, hoses, radiator, and water pump) for damage.

3. Replace Damaged Components

Hoses:
- Use a hose clamp tool to remove the clamps.
- Disconnect the damaged hose and replace it with a new one.
- Reattach hose clamps securely.
Radiator:
- Drain the coolant using a drain pan.
- Remove the radiator by unscrewing the mounting bolts and disconnecting the transmission cooler lines (if equipped).
- Install the new radiator and reconnect all hoses and bolts.
Water Pump:
- Drain the coolant.
- Remove the serpentine belt and any components obstructing access to the water pump.
- Unbolt and remove the old water pump, clean the mounting surface, and install the new pump with a new gasket.
- Reassemble all components and reattach the serpentine belt.

4. Refill Coolant

Fill the cooling system with the appropriate type of coolant as specified in the owner's manual.
Start the engine and allow it to reach operating temperature, checking for leaks.

5. Final Checks

Reconnect the battery.
Monitor the coolant level for the next few days and check for any signs of leaks.
