Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool before starting.
Disconnect the battery to prevent any electrical issues.

2. Inspect the Coolant Reservoir

Remove the coolant reservoir cap.
Visually inspect the reservoir for any cracks or damage.
If damaged, replace the reservoir.

3. Examine the Radiator

Remove any obstructions to access the radiator.
Inspect for leaks or damage, particularly at the seams.
If leaks are found, replace the radiator.

4. Check the Hoses

Trace all coolant hoses from the engine to the radiator.
Look for cracks, fraying, or loose clamps.
Replace any damaged hoses and ensure all clamps are tightened to the specified torque.

5. Inspect the Water Pump

Locate the water pump and inspect for coolant leakage at the pump housing or from the weep hole.
If there is a leak, remove the old water pump and install a new one, ensuring to replace the gasket.

6. Examine Engine Block and Head Gasket

Check for any signs of coolant leaks around the engine block and cylinder head.
If the head gasket is suspected to be leaking, a full engine disassembly may be required to replace it.
