Solution

1. Preparation

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

2. Visual Inspection

Reservoir Check: Inspect the coolant reservoir for cracks or leaks. Replace if damaged.
Hose Inspection: Examine all hoses connected to the cooling system. Look for bulges, cracks, or signs of wear. Replace any damaged hoses.
Radiator Examination: Inspect the radiator for any visible coolant leaks or corrosion. If leaks are found, consider replacing the radiator.

3. Pressure Testing

Pressure Tester Setup: Attach the pressure tester to the coolant reservoir cap. Ensure a proper seal.
Pressurizing System: Pump the tester to the manufacturer’s specified pressure (usually around 15-20 psi).
Leak Detection: Monitor for any drop in pressure which indicates a leak. Observe the engine bay and under the vehicle for any visible leaks.

4. Check Water Pump

Inspect Water Pump: Look for leaks around the water pump area, particularly at the weep hole.
Replacement: If the water pump shows signs of leaking, remove and replace it according to manufacturer specifications.

5. Refill and Test

Coolant Refill: If any leaks were repaired, refill the cooling system with the correct type of coolant.
Bleed Air: Run the engine with the radiator cap off to bleed any air from the system.
Final Check: After running the engine, check again for any leaks around the repaired areas.
