I recently purchased a 2018 F32 440i and has so far been great... other than coming across a small hole in the front radiator that feeds coolant through the air to water intercooler. The main expansion tank appears to be holding its coolant level, however, the smaller tank for the intercooler pretty much drains minutes after being filled through the hole in the front of the radiator. My main concern, as I have been driving the vehicle like this and presumably so was the previous owner before I bought it, will this damage anything to have the second loop for the intercooler running dry? I’m not sure how these two loops that go to the intercooler, motor, and 2 separate radiators are plumbed. Just don’t want to damage the electric water pump or any other components before I can repair it, or replace it. Any insight will be appreciated, thanks!
