what should I do if my Ford Mustang S650 (2024-Present) engine is knocking?

Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to ensure safety while working on the engine.
• Allow the engine to cool completely before starting.

2. Change Engine Oil

• Sub-steps:
  1. Raise the vehicle securely on jack stands.
  2. Drain the old oil using an oil pan; remove the oil drain plug and let it flow for several minutes.
  3. Replace the oil filter with a new one; ensure the old filter gasket is removed.
  4. Reinstall the oil drain plug and tighten to the manufacturer’s torque specifications (typically around 25-30 ft-lbs).
  5. Fill the engine with new oil that meets Ford specifications (usually 5W-30 or 0W-20).
  6. Start the engine and let it idle for a few minutes; check for leaks.

3. Address Internal Issues

• Sub-steps:
  1. If compression tests show low readings, consider disassembling the engine to inspect pistons, rings, and bearings.
  2. Replace any damaged components found during inspection, including bearings or piston rings.
  3. Reassemble the engine carefully, ensuring all torque specifications are followed.
  4. Reconnect the negative battery terminal.

4. Fuel System Inspection

• Sub-steps:
  1. Check the fuel injectors for proper operation; clean or replace if necessary.
  2. Inspect the fuel filter for clogs and replace if needed.
  3. Verify that the fuel pump is functioning correctly and supplying adequate pressure.
