caleb 0 Report post Posted October 26, 2008 (edited) My Coolant low telltale sign is on. When I pour coolant into the coolant expansion tank, I could see coolant flowing out as soon as I top up. In fact, it left a pool of coolant on the ground. What could have gone wrong? some hose is broken??? Edited October 26, 2008 by lufu Quote Share this post Link to post Share on other sites

My sensor is also faulty but haven't got round to replacing it, sometimes if I just wiggle the wire it will work for a few trips. Quote Share this post Link to post Share on other sites

bmwstz 0 Report post Posted October 26, 2008 Is the coolant coming out from the overflow bottle or elsewhere? Also, what model and year do you have? Quote Share this post Link to post Share on other sites
