Скачать или смотреть New Catalytic Converter Smell

Just bought a new car or finished an expensive repair, and now your car smells like rotten eggs, chemicals, or something’s burning? Don’t freak out! That “new catalytic converter smell” is a normal part of breaking in new exhaust parts. When a brand-new catalytic converter heats up for the first time, it burns off leftover oils and factory coatings—leading to temporary funky odors.

The weird smell is strongest during your first few drives, especially if you idle or accelerate hard, but it usually fades away within 200-500 miles (about two weeks for most drivers). If the odor sticks around beyond that, it’s time for a pro check—there could be a bigger issue like unburned fuel or an exhaust leak.

Pro tips: take your car for a steady highway cruise to speed up the break-in, and check your oil/exhaust just in case. Don’t mask the smell with air fresheners—crack a window and it’ll pass. If your check engine light stays off and the car feels fine, you’re probably just smelling manufacturing leftovers. No need for panic—or unnecessary repairs!

Don’t let new car smells ruin your ride. Watch the video for everything you need to know about weird odors from new catalytic converters, when it’s normal, and when to see a mechanic.
