Sub-step 1: Remove the engine cover if necessary to access the coolant reservoir and related components.
Sub-step 2: Visually inspect all hoses and connections for cracks or leaks.
Sub-step 3: Inspect the water pump and the area around it for any signs of leakage.

3. Repair Leaks

Sub-step 1: If leaks are found, replace the damaged hoses or connections.
Sub-step 2: If the water pump is leaking, drain the coolant and remove the old pump using a socket set.
Sub-step 3: Install the new water pump, ensuring all bolts are torqued to the manufacturer's specifications.

4. Refill Coolant

Sub-step 1: Use the appropriate coolant type specified by BMW.
Sub-step 2: Fill the reservoir to the recommended level.
Sub-step 3: Start the engine and allow it to reach operating temperature while checking for leaks.

5. Bleed the Cooling System

Sub-step 1: Use a cooling system bleeder tool to remove air bubbles, if applicable.
Sub-step 2: Monitor the coolant level during the bleeding process and top off if necessary.
