2018 BMW 530i coolant issue

Topic starter

Hello, I recently experienced significant coolant loss with my car. I have finished a whole gallon of coolant within a month. I checked the engine bay and couldn't locate any signs of a coolant leak. The coolant consumption seems to be slower when driving normally, but the reservoir goes empty after intense driving. Any idea of what is going on here? Thanks!

Well I hope it's not blowing a head gasket. Try my video. How to tell if your head gasket is bone Scotty if not that have the system pressure check to see where it's leak is


Thanks, Scotty! I hope it's not a blown head gasket. I have watched your video, but I'm unsure if I can use the same method to check whether bubbles are coming up from the radiator because mine doesn't have a cap on the radiator. Is it possible to check the reservoir instead? Also, as you mentioned, exhaust gas would come up from the radiator if there's a blown head gasket. My car has previously popped up a check engine light for a "small EVAP leak," do you think it's related?
