Solution

1. Preparation

Gather necessary tools and parts.
Ensure the engine is cool and the vehicle is parked on a level surface.
Disconnect the battery to eliminate electrical hazards.

2. Inspect and Repair Leaks

2.1 Coolant Reservoir Inspection

Remove the coolant reservoir cap.
Check for cracks or damage. If found, replace the reservoir.

2.2 Radiator and Hose Check

Visually inspect the radiator and hoses for leaks.
If leaks are found, replace damaged hoses and/or the radiator.

3. Perform a Cooling System Pressure Test

Attach a pressure tester to the radiator cap.
Pump the tester to the recommended pressure (usually around 15-20 psi).
Observe for any drops in pressure, which indicates a leak.

4. Address Internal Engine Issues

4.1 Oil and Coolant Inspection

Drain engine oil into a clean container.
Inspect for a milky appearance, which indicates coolant contamination.
If contamination is present, consider replacing the head gasket.

4.2 Heater Core Inspection

Check the passenger side for dampness or a sweet smell.
If the heater core is leaking, replace it.
