Solution

1. Preparation

Tools Required: Coolant pressure tester, flashlight, clean rags, safety glasses, gloves.
Ensure the engine is cool before starting work to avoid burns.

2. Visual Inspection

Sub-steps:
1. Park the vehicle in a well-lit area and allow the engine to cool down.
2. Use a flashlight to inspect the ground under the vehicle for any signs of coolant leakage.
3. Check the color and consistency of any fluid found (coolant is typically green, orange, or pink and has a sweet smell).

3. Check Coolant Reservoir

Sub-steps:
1. Open the hood and locate the coolant reservoir.
2. Inspect the reservoir for cracks or damage.
3. Check the coolant level and ensure it is within the recommended range.

4. Examine Hoses

Sub-steps:
1. Follow each coolant hose from the engine to the radiator and look for cracks, bulges, or signs of wear.
2. Squeeze the hoses to check for any soft spots or leaks.
3. If any hoses are damaged, mark them for replacement.

5. Inspect Radiator

Sub-steps:
1. Check the radiator for any signs of physical damage, such as dents or corrosion.
2. Look for signs of coolant stains around the radiator seams.
3. If damage is found, consider replacing the radiator.

6. Pressure Test

Sub-steps:
1. Attach the coolant pressure tester to the coolant reservoir or radiator cap.
2. Pump the tester to apply pressure to the cooling system (follow manufacturer's pressure specifications).
3. Observe the pressure gauge; if it drops, inspect the cooling system for leaks while under pressure.
