I have a 2010 Hyundai Tucson that i got the radiator and valve cover gasket replaced due to a coolant leaking issue. The mechanic suggested to replace radiator and coolant flushing and top up.

After 2 days, about 50KM drive, car suddenly turned off while I was stuck in traffic and I noticed slight smoke coming from engine bay with sweet burnt smell when I had it parked. (Car turned on again with temp rising and I had it parked safely about 2km drive)

Any advice?
