The +22 year old E36 expansion tank can be a fickle mistress at the best of times and are well known to have a high failure rate. It is common for their constant exposure to high temperatures and pressures to fatigue the plastic over the years and cause cracks and leaks. Practice some preventative maintenance and replace this part to ensure your E36 stays loyal to you.

Don’t waste your money on cheap aftermarket parts. This quality option has metal sleeve inserts inside each of the flanges to reinforce the plastic.
