Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and disconnect the battery for safety.
Have a clean container ready to catch any leaking coolant.

2. Inspect Coolant Reservoir

Remove the coolant reservoir cap.
Check for cracks or damage.
If damaged, replace with a new coolant reservoir.

3. Inspect and Replace Hoses

Locate all coolant hoses connecting the radiator and engine.
Visually inspect for cracks or wear.
If damaged, loosen the clamps, remove the hose, and install a new hose. Ensure clamps are tight.

4. Check and Repair Radiator

Inspect the radiator for leaks, focusing on the seams and core.
If leaks are found, consider using a radiator sealant for minor leaks or replace the radiator if damage is extensive.

5. Examine Water Pump

Locate the water pump and inspect for coolant leakage around the gasket.
If leaking, remove the water pump by loosening the mounting bolts, replace the gasket, and install a new water pump, ensuring proper torque specifications.
