Vent/Bleed Coolant System on BMW E60/E90

Introduction

If you are unsure that your car's battery will be strong to handle 12-15 minutes of the venting process attach a battery charger!

Video Overview

    • Insert key in the dash or steering column.

    Edit

    • With foot OFF the brake (don't want to start the car), push the start button (headlamps and interior systems come on).

    Edit

    • Turn both temp dials as high as they will go and put the fan on the lowest setting.

    Edit

    • Push the accelerator pedal in for ten seconds then let go - you will hear the water pump cycle on.

    Edit

    • Set a timer for 12-15 minutes. In this time period, you will hear the water pump cycle on and off and coolant gurgling at the reservoir.

    Edit

    • After 12-15 minutes turn the car off, remove the reservoir cap and check the fluid - it should be slightly below where you started.

    Edit

    • Start your car. Watch your temperature. If the car will run without overheating you're done. If you will notice that the temperature is rising repeat these steps.
