Message: <blockquote data-quote="astroboy" data-source="post: 339923" data-attributes="member: 4527">Yep... my E90 is running electric water pump too.. meaning it doesn't matter how fast you are driving, or how much air is gushing into the radiator, if the electric water pump stop spinning, your coolant is not circulating. Another effort to squeeze more HP from the engine to the wheels. Too bad my E90 steering pump is still hydraulic instead of on-demand electric, which is a lot more useful than the electric on-demand water pump.The beauty about on-demand electric pump is, be it coolant, engine oil or power steering, when you need acceleration, it will cut off until critically needed. Just like VVTi in Toyota, as long as u keep pedaling aggressively, it doesn't matter what cabin temperature u set, the compressor just won't cut in!! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> Good? U be the judge.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />Oh yes, one more beauty about electric water pump is when you are really overheated, or after spirited drive, the pump will keep running with the fan keep spinning with coolant keep circulating, even after you shut the engine and remove  your FOB!! <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /> just like a turbo timer.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite7" alt=":p" title="Stick Out Tongue    :p" loading="lazy" data-shortname=":p" />Sometime when my wife came home at night, after she came into the house, all house doors lock, I can still hear the E90 fan still spins.. <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite9" alt=":eek:" title="Eek!    :eek:" loading="lazy" data-shortname=":eek:" /></blockquote>
