Solution

1. Preparation

Gather all necessary tools and parts.
Allow the engine to cool completely before starting work.
Disconnect the negative battery terminal to ensure safety.

2. Identify the Source of the Leak

Coolant Reservoir and Radiator Inspection:
- Remove the engine cover if equipped.
- Inspect the coolant reservoir for cracks; replace if damaged.
- Check the radiator for physical damage or corrosion.
Hose Inspection:
- Trace all coolant hoses from the engine to the radiator.
- Tighten any loose hose clamps; replace any hoses that show signs of wear.

3. Repairing Leaks

If the Water Pump is Leaking:
- Drain coolant from the system into a clean container.
- Remove the water pump by disconnecting hoses and unbolting it.
- Clean the mounting surface and install a new water pump with a new gasket.
- Refill the system with the appropriate coolant.
If the Radiator is Leaking:
- Drain coolant from the radiator.
- Remove the radiator by disconnecting hoses and unbolting it from the frame.
- Install the new radiator and reconnect all hoses securely.
- Refill the cooling system with the correct coolant type.

4. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature while monitoring for leaks.
Check the coolant level and add more if necessary.
