Solution

1. Preparation

Gather Tools and Parts:
- Pressure tester
- Coolant (if needed for top-off)
- Safety gloves
- Clean rags
Safety Warnings: Allow the engine to cool completely before starting the inspection to avoid burns.

2. Inspect the Coolant Reservoir

Step 1: Open the hood and locate the coolant reservoir.
Step 2: Visually inspect for any cracks, leaks, or damage.
Step 3: Check the coolant level against the markings on the reservoir.

3. Check Hoses and Connections

Step 1: Trace the hoses leading from the radiator to the engine.
Step 2: Feel along the hoses for any wet spots or signs of coolant leakage.
Step 3: Inspect hose clamps for tightness and corrosion.

4. Examine the Radiator

Step 1: Locate the radiator and inspect the core for signs of leaks or damage.
Step 2: Check the seams and connections at both the top and bottom of the radiator for coolant stains.

5. Perform a Pressure Test

Step 1: Attach the pressure tester to the radiator cap or reservoir.
Step 2: Pump the tester to apply pressure according to the manufacturer’s specifications (usually around 15-20 psi).
Step 3: Observe the gauge; if it holds pressure, check for leaks. If it drops, inspect for leaks visually or by feel.

6. Check Engine Oil

Step 1: Remove the oil dipstick and inspect the oil for a milky appearance, indicating coolant contamination.
Step 2: If contamination is present, further inspection of the head gasket may be necessary.
