My Malibu has an antifreeze smell. I notice it the most when the defrost is on. The car doesn’t overheat, there is no fluid on the floorboard, I assume this means it is not a heater core. I ran a hose from the radiator reservoir vent port away from the vents by the windshield. Thought it may be venting from there into the cabin. I am not loosing antifreeze either. I had the same problem in my Cruze when I owned it. This will be the last Chevy I own for sure lol. Any thoughts? Car has 112000 miles on it. Oh do you recommend flushing the trans on this make car with this amount of miles? Thanks. Jason
Well unfortunately it usually means it is the heater core. The heater core is just generally seep so you don't really get any leakage but man does it stink. My advice is the price your tesla system over maybe half an hour and if the pressure does go down and you don't see the leak anywhere then you know it was inside the heater core which you can't see
