Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool before starting.
Wear safety glasses and gloves.

2. Inspect Coolant Reservoir

Open the hood and locate the coolant reservoir.
Visually check for any cracks or leaks.
If damaged, replace the coolant reservoir with a new one.

3. Check Radiator and Hoses

Inspect the radiator for any visible damage or corrosion.
Check all hoses connected to the radiator for cracks or loose clamps.
Tighten or replace any loose or damaged hoses as necessary.

4. Use Pressure Tester

Attach the pressure tester to the coolant reservoir or radiator cap.
Pump the tester to the recommended pressure (usually around 15-16 psi).
Observe for any drops in pressure or leaks. If leaks are found, note the location for repair.

5. Inspect Water Pump

Check the water pump for signs of coolant leakage, usually indicated by wetness or a residue around the pump.
If leaking, replace the water pump according to manufacturer specifications.

6. Clean Up and Refill

Clean any spilled coolant and ensure no contaminants enter the system.
Refill the cooling system with the appropriate type of coolant if needed.
Recheck all connections and components for tightness.
