2007 Mini Cooper Question: Coolant leak after engine is shut off.
After shutting off the engine taking a drive from office to home 15-20 miles, Coolant starts leaking continuously at 2 spots down the bumper. Got diagnosed for two times from two different persons wasting time and money. Performed thermostat test and done pressure test on reservoir, radiator as well the hoses & got result of good holding pressure in all three components. couldn't diagnose the exact reason for leak and still worrying of the coolant level running out from the reservoir and got frustrated refilling it. Some says its water pump problem. I have video of it. But couldn't find the option to upload it. Can anyone tell what might be the possible causes of coolant leak after the engine is shut off? - Naveen srinivasa
Is it still hot when it was pressure tested. Did you have it running while pressure testing, it can build pressure at shut down after driving, with a heating expansion issue allowing the leak. Just comments of things I have had to do. Create the same conditions that allows the leak while testing. - ProfessorG
