Solution

1. Preparation

Tools Needed: Safety gloves, safety glasses, flashlight, coolant pressure tester, paper towels.
Ensure the engine is cool before starting any inspection to avoid burns.
Disconnect the vehicle's battery for safety.

2. Visual Inspection

Look under the vehicle to identify any puddles of coolant. Use paper towels to soak up any fluid to determine color and consistency.

3. Inspect Coolant Reservoir

Open the hood and visually check the coolant reservoir for any visible cracks.
If cracks are found, proceed to replace the reservoir.

4. Check Hoses and Connections

Inspect all hoses leading to and from the coolant reservoir for cracks or signs of wear.
Tighten any loose connections. Replace any damaged hoses.

5. Conduct Pressure Test

Attach the coolant pressure tester to the reservoir cap.
Pump the tester to pressurize the system and observe for any leaks.
Look for leaks around hoses, the radiator, and engine components during this test.

6. Inspect Engine Components

Check the water pump for any signs of coolant leaking from the weep hole.
Inspect the radiator for any punctures or corrosion.
Check engine gaskets for signs of leakage; replace any faulty gaskets.

7. Examine Heater Core

Check the passenger side floor and under the dashboard for dampness or a coolant smell, indicating potential heater core leakage.
If leaking, the heater core will need to be replaced.
