  • Disconnect the battery for safety.

Tools Required:

  • Socket set
  • Torque wrench
  • OBD-II scanner
  • Fluid catch basin
2. Identify Fluid Type
  • Use a clean cloth to absorb a small amount of the fluid.

3. Repair Coolant Leaks
  • Inspect and Replace Hoses:

    • Remove any covers if necessary.
    • Check hoses for cracks or deterioration.
    • If damaged, replace with OEM hoses, ensuring proper fit and securing with clamps.
  • Check Reservoir:

    • Inspect the coolant reservoir for cracks.
    • If damaged, replace it with a new reservoir.
4. Repair Oil Leaks
  • Inspect Seals and Gaskets:
    • Check the oil filter and drain plug for leaks.
    • Replace any faulty seals or gaskets.
5. Repair Air Suspension Leaks (if applicable)
