When it comes to maintaining your BMW E46 , properly bleeding the cooling system is a crucial step. Here are simple steps you can follow to ensure your radiator is working efficiently:
Step-by-step instructions:
1. Start your BMW while stationary:
- Turn on the air conditioning.
- Set the heater to the highest temperature.
- Select the lowest fan setting.
2. Let the engine run:
- Start the engine with the radiator cap open.
- Let the vehicle idle.
3. Accelerate:
- Give it half throttle three times to activate the circulation.
- Make sure the motor sucks in the water.
4. Refill:
- After the engine has sucked in the water, refill any missing water.
5. Observe the bubbles:
- Wait until no more bubbles appear in the coolant.
- This indicates that the cooling system is bled.
6. Close the lid:
- Close the radiator cap carefully.

Why is venting important?
A properly bled cooling system ensures efficient cooling of the engine, prevents overheating and contributes to the long-term performance of your vehicle. Bleeding is especially important after maintenance or changing coolant to prevent air bubbles in the system.
