Solution
1. Preparation
  • Gather tools and parts needed for repairs.
  • Ensure the engine is cool and disconnect the battery to avoid electrical hazards.
  • Tools required: Socket set, torque wrench, OBD-II scanner, coolant tester.
2. Check Oil Level
  • Remove the dipstick and wipe it clean.
  • Reinsert the dipstick and remove it again to check the oil level.
  • If low, add the correct type of oil as specified by the manufacturer.
3. Inspect Oil Filter
  • Using an oil filter wrench, remove the oil filter.
  • Check the rubber O-ring for proper seating and inspect for any damage.
  • Replace with a new oil filter if necessary, ensuring it is properly tightened.
4. Inspect Cooling System
  • Check the coolant reservoir for the correct fluid level. If low, add the appropriate coolant mixture.
  • Inspect hoses for any signs of wear or leaks and replace them if necessary.
5. Thermostat Check
  • Drain coolant to lower the level below the thermostat.
  • Remove the thermostat from the engine block and test it by placing it in hot water.
  • Replace if it does not open at the specified temperature (usually around 88-90°C for BMW).
6. Radiator Inspection
  • Inspect the radiator for blockages or debris.
  • Clean the radiator fins with compressed air or a soft brush.
  • Check for leaks and ensure the radiator cap is functioning properly.
