The Ford Taurus is famous for having leaking heater core. It is located on the passenger side inside the passenger compartment and inside the dashboard. It costs about $1000 to get a mechanic to fix it.
At the top of the garlic there is something quite hairy that if you cut off, it gives out a very strong smell.
Maybe the heater core is leaking.
Make sure it is full of coolant. There probably is a small leak causing the smell. Check it cold as sometimes it leaks cold but not hot.
if you smell coolant and your windows are fogged possibly it could be the heater core.
Might be a leaky heater core, the anti freeze in the coolant has a sweet smell/taste.
Possibly the catalylic converter.
Bravada smell coolant. That's how they greet each other.
A 2000 Ford Taurus 3.0 engine may smell of antifreeze at a stop without requiring frequent additions of coolant due to a minor leak or seepage in the cooling system, such as a faulty hose or gasket, that evaporates quickly when the engine is running. Another possibility is that the coolant is leaking internally, such as through a head gasket failure, but not enough to cause a noticeable drop in the coolant level. Additionally, residual coolant on the engine or exhaust components can emit a smell when the engine is hot. Regular inspection of the cooling system is advisable to identify the source of the odor.
A poisonous gas with a strong smell, that is used in industries and causes air pollution
The main part of diesel fuel is kerosene, which produces thick black smoke, and gives that smell that is commonly associated with diesel. most likely if it is white smoke, it is antifreeze, if it has a blue tint to it, it is oil. the smell of burnt diesel is rather strong so it could cancel the burnt oil smell, or on the other hand it could be coolant, because burned coolant doesn't have a strong smell. I would check your coolant and oil levels, and check your coolant for having oil in it.
The head gasket sits between the head and the engine block if it is leaking out where you can see the coolant, yes you can smell the coolant if it is leaking into the engine no you cannot smell the coolant. You can check the oil to see if it has coolant in the oil if it does then the head gasket might be blown.
