Why does it smell like it's hot but the temperature guage says it's fine

Hello, it sounds like there may be a small coolant leak somewhere, creating a smell that is notable. I'd have a pressure test of the cooling system performed to see if there are any hoses or pipes that are leaking externally. Also check your water pump to see if there is any coolant weeping there.
