Solution
1. Preparation
  • Gather tools and parts needed for the repair.
  • Ensure the engine is cool to prevent burns.
  • Disconnect the negative battery terminal.
2. Locate and Repair Coolant Leak
  • Inspect hoses:
    • Examine all hoses connected to the radiator and engine for cracks or leaks.
    • Replace any damaged hoses with new ones.
  • Check radiator:
    • Inspect the radiator for any visible leaks or corrosion.
    • If leaking, replace the radiator.
  • Inspect water pump:
    • Check the water pump for leaks around the seals.
    • Replace the water pump if it shows signs of failure.
3. Refill Coolant
  • Drain old coolant:
    • Place a drain pan under the radiator and open the drain plug to remove old coolant.
  • Flush the system (if necessary):
    • Use a garden hose to flush the cooling system, ensuring all old coolant is removed.
  • Add new coolant:
    • Mix the correct type of coolant (BMW coolant or equivalent) with distilled water (50/50 mixture).
    • Refill the coolant reservoir to the appropriate level.
4. Recheck System
  • Bleed the cooling system:
    • Start the engine with the radiator cap off to allow any trapped air to escape, adding coolant as needed.
  • Replace radiator cap:
    • Ensure the radiator cap is secure and functioning properly.
