Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and parked on a level surface.
Wear safety gloves and goggles.

2. Inspect Coolant Reservoir

Remove the cap from the coolant reservoir.
Check for any visible cracks or deterioration.
If damaged, replace the reservoir.

3. Check Hoses and Connections

Use pliers to loosen clamps and disconnect hoses from the radiator and engine.
Inspect hoses for bulges, cracks, or signs of wear.
Replace any damaged hoses with new ones.

4. Examine the Radiator

Visually inspect the radiator for leaks or corrosion.
If leaks are found, consider replacing the radiator.
Ensure all fittings and connections are tight.

5. Pressure Test the Cooling System

Attach a pressure tester to the coolant reservoir opening.
Pump the tester to the required pressure specified in the vehicle manual (usually around 15-20 psi).
Monitor for any pressure drop, which indicates a leak.

6. Inspect Water Pump

Locate the water pump (generally near the timing belt/chain).
Check for any coolant leaking around the pump shaft.
If a leak is found, replace the water pump.

7. Final Inspection and Reassembly

Reconnect all hoses and clamps securely.
Refill the cooling system with the appropriate coolant.
Start the engine and monitor for leaks.
