I’ve smelled Coolant since my stinger was new. I notice it more when I’ve driven the car hard. I never smell it in the car but I can get a hint of it when I open the door or stand near the hood. I have not seen any leaks or loss of coolant. The car has 5000km on it now. Do you guys notice the same thing? My 2015 rubicon had a bit of a coolant smell as well and same with my genesis r spec v8. I’m guessing it’s just the way the coolant system works and it’s just the smell from the breather.
