Solution

1. Preparation

Gather tools and parts needed for inspection and potential repair.
Tools Required:
- Pressure tester
- Socket set
- Screwdrivers
- Shop towels for cleanup
Safety Warnings:
- Allow the engine to cool before opening the cooling system to avoid burns.

2. Inspect Coolant Reservoir

Remove the coolant reservoir cap carefully.
Visually inspect the reservoir for cracks or leaks.
If the reservoir is damaged, replace it with a new one.

3. Examine Hoses and Clamps

Start from the radiator and trace all hoses to the engine.
Check for any signs of bulging, cracks, or loose clamps.
Tighten any loose clamps and replace damaged hoses as necessary.

4. Check Water Pump

Locate the water pump and inspect for any signs of coolant leakage around the pump housing.
If leakage is observed, replace the water pump.

5. Test Cooling System Pressure

Connect the pressure tester to the radiator or reservoir.
Pump the tester to the specified pressure (usually between 15-20 psi).
Observe for any drop in pressure, which indicates a leak in the system.
If a leak is identified, repair or replace the affected component.
