how to check for coolant leaks in Ford Mustang S550 (2015-2023)

Solution

1. Preparation

• Gather necessary tools and materials.
• Ensure the engine is cool before starting work.
• Disconnect the battery to prevent electrical issues.

2. Visual Inspection

• Tools Required: Flashlight
• Inspect the engine bay, radiator, and hoses for any visible signs of coolant leaks.
• Check the reservoir for cracks or damage.

3. Pressure Testing

• Tools Required: Cooling system pressure tester
• Attach the pressure tester to the radiator cap opening.
• Pump the tester to the recommended pressure (usually around 15-20 psi).
• Observe for any drops in pressure and listen for hissing sounds indicating leaks.

4. UV Dye Test

• Tools Required: UV dye, UV light
• Add UV dye to the coolant reservoir as per manufacturer instructions.
• Allow the engine to run for a few minutes to circulate the dye.
• Use a UV light to inspect the engine bay and hoses for glowing dye, indicating leak locations.

5. Repairing Detected Leaks

• If any leaks are identified during inspection or testing, proceed with the appropriate repairs:
  • Hoses: Replace any damaged hoses and ensure clamps are tight.
  • Radiator: If the radiator is leaking, either repair it with epoxy or replace it if the damage is severe.
  • Water Pump: Replace the water pump if leakage is detected from the weep hole.
