Solution

1. Preparation

Tools Required: Coolant pressure tester, socket set, screwdrivers, rags for cleanup.
Ensure the engine is cool before starting work to prevent burns.
Disconnect the battery to prevent any electrical issues.

2. Visual Inspection

Clean the area around the suspected leak with a rag.
Look for obvious signs of leakage, such as wet spots or coolant trails.

3. Inspect and Replace Hoses

Sub-steps:
- Use a socket set to remove any clamps securing the hoses.
- Remove the hoses and inspect for cracks or bulging.
- Replace any damaged hoses with OEM parts.
- Reinstall hoses and secure with clamps, ensuring a tight fit.

4. Check Radiator and Cap

Remove the radiator cap and inspect the rubber seal for wear.
If damaged, replace the radiator cap with a new one.
Inspect the radiator for any leaks or damage; replace if necessary.

5. Water Pump Inspection

Inspect the area around the water pump for signs of coolant leakage.
If leaking, remove the water pump using a socket set and replace it with a new pump following the manufacturer’s specifications for torque values during reinstallation.

6. Pressure Testing

Sub-steps:
- Attach the coolant pressure tester to the radiator neck.
- Pump the tester to the recommended pressure (typically around 15-20 psi).
- Observe for any drops in pressure or coolant leaking from the system.
- Identify and repair any leaks found during this test.
