Solution

1. Review Maintenance Schedule

Review your BMW X3 F25 owner's manual for the recommended coolant service interval.
Typically, BMW recommends flushing the coolant every 2 to 4 years or every 30,000 to 50,000 miles, depending on driving conditions.

2. Check Coolant Condition

Inspect the coolant reservoir for any signs of contamination or sediment.
If the coolant appears discolored or rusty, a flush is necessary regardless of mileage.

3. Perform Coolant Flush (if required)

a. Preparation

Gather all necessary tools and parts.
Ensure the engine is cool and park the vehicle on a level surface.

b. Drain Coolant

Locate the drain plug on the radiator and place a container underneath.
Remove the drain plug to allow the old coolant to flow out completely.

c. Flush System

Attach a garden hose to the top radiator hose.
Run water through the system until it runs clear, ensuring all old coolant is removed.

d. Refill with New Coolant

Replace the drain plug securely.
Fill the system with the appropriate type of BMW-approved coolant mixed with distilled water (50/50 ratio).
Start the engine and let it run with the radiator cap off to allow air to escape, topping off as necessary.

4. Dispose of Old Coolant

Take the old coolant to a recycling center or disposal facility.
