my BMW X5 G05 (2019-2024) has a low coolant warning what should I check

Solution

1. Preparation

• Tools Required: Flathead screwdriver, socket set, coolant catch pan, funnel, gloves.
• Allow the engine to cool completely before starting work to avoid burns.

2. Check and Refill Coolant

• Sub-steps:
  1. Locate the coolant reservoir.
  2. Remove the cap slowly to release any pressure.
  3. If the coolant level is low, add the manufacturer's recommended coolant mixture (usually a 50/50 mix of BMW coolant and distilled water).
  4. Replace the cap securely.

3. Repair Leaks

• Sub-steps:
  1. If a leak is identified in a hose or connection, tighten any loose clamps.
  2. If there are cracks in hoses, replace them with OEM parts.
  3. For radiator leaks, consider using a radiator sealant as a temporary fix or replace the radiator if the damage is severe.

4. Flush and Replace Coolant (if contaminated)

• Sub-steps:
  1. Place a coolant catch pan under the vehicle.
  2. Disconnect the lower radiator hose and let old coolant drain completely.
  3. Reconnect the hose and fill the system with fresh coolant through the reservoir.
  4. Run the engine with the heater on to allow air to escape the system, topping off coolant as necessary.
