Coolant has a smell that is very difficult to describe; it smells sweet, yet a little like rubber; It has a green color almost like Gatorade. Old coolant can be brown and smell quite rancid.

Your description sounds like engine coolant to me.

You may have a bad head gasket and or a cracked head.

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.

Likely as not there is a coolant leak, perhaps in the heater core.

If your going through coolant then you have an internal head gasket leak you smell coolant because its getting into cylinder and burning

I hope you like the smell of warm coolant in your car. Also, prepare yourself for a nice footbath of warm coolant.

get a coolant system pressure test, there may be a leak in the heater core.

If your car is using oil as in you have to keep topping it up it is probably oil getting past the rings after car heats and expands. If your car is using coolant, then you may have a small coolant leak at the head gasket, allowing coolant to enter the cylinder and be burned with the gas , resulting in what looks like smoke but does not smell like oil.

You may need to have your engine compression tested. To make sure it's not mixing your oil and coolant together. This will be a sign of a bad head or bad head gasket.

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.

coolant smell/leakyes more than likely that's your prob. but could be maybe a hose.

Sounds like your heater core may have a pinhole leak in it

A sweet smell is usually coolant being burned, check your coolant level and oil ( look for milky appearance ) as it may be a head gasket leak. A coolant leak on the outside of the motor may indicate a leak somewhere in the radiator or one of the hoses. When an AC line is leaking I have heard some people describe the smell as sweet.

If it is not actually over heating, then if the smell is outside the car, look for coolant leaks around the head and the thermostat cover. Inside the car could be a leaking heater coil.

Maybe a head gasket leak they're hard to see and can cause coolant leakge and you might smell the coolant in the car

if you can smell antifreeze, you have an antifreeze leak somewhere. you need to clean engine then look for coolant . it will generally pool on ground under vehicle unless it is leaking onto engine and burning off. note that the coolant will run so you may have to trace back to the actual leak. check all coolant fittings, such as hoses and check area round water pump.
