The expansion tank in your BMW is known for failing, so with that in mind, ECS Tuning has created a kit to make your life a little easier. We have included a high quality Vaico expansion tank, along with a level sensor, cap and seal, as well as the coolant line from the tank along with clamps. Also this kit includes an ECS aluminum bleeder screw that won't strip out or break like conventional plastic screws. So whether you are doing preventative maintenance or fixing a failed tank, this kit is a great option.
