what does it mean if my Ford Mustang S550 (2015-2023) shows a coolant warning

Solution

1. Preparation

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

2. Coolant Level Adjustment

• Remove the coolant reservoir cap.
• If the coolant is low, add the appropriate mixture of coolant and water (50/50 mix recommended).
• Recheck the level after adding and close the cap securely.

3. Leak Repair

• If leaks are found:
  • Tighten any loose hose clamps.
  • Replace damaged hoses using a socket set.
  • If the radiator is damaged, remove it:
    • Disconnect the upper and lower hoses.
    • Remove mounting bolts and lift the radiator out.
    • Install the new radiator by reversing the removal steps.

4. Thermostat Replacement (if faulty)

• If thermostat is not functioning:
  • Drain the coolant from the radiator.
  • Disconnect the upper radiator hose.
  • Remove the thermostat housing bolts using a socket set.
  • Replace the thermostat and gasket, ensuring the new gasket is seated properly.
  • Reassemble the housing and hoses, then refill coolant.

5. Water Pump Replacement (if necessary)

• If the water pump is defective:
  • Drain the coolant system.
  • Remove the serpentine belt.
  • Disconnect the water pump from the engine by removing mounting bolts.
  • Install the new water pump, ensuring proper gasket placement.
  • Reassemble the belt and refill the coolant system.
