The E36 is an excellent vehicle with great balance - the perfect car for spirited driving. However, while BMW did a great job with styling and chassis balance, the cooling system is known to be a weak link overall. The factory plastic expansion tank in particular is known to either blow up, crack, or the plastic nipple for the return line breaks off.  

Our 5052 aluminum wrinkle black powder coated expansion tank is an excellent upgrade or preventative maintenance item that addresses all of the issues with factory E36 expansion tanks. Direct fit with no modifications. In addition to the aluminum expansion tank, this kit includes an aluminum bleeder screw, new expansion tank cap, new coolant level sensor, and more.

Chances are your E36 needs a new expansion tank right now, make sure this is the last expansion tank you ever buy. With a full aluminum construction and wrinkle black powder coat, this expansion tank will be durable and the last expansion tank you will ever need purchase. One and done, make sure the job is done correctly and fixed forever. This kit comes with all the components you need to replace your expansion tank the right way and get back to enjoying your E36.
