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.
Yes anti freeze has a sweet smell, at least in comparison to the normal fuel and oil smells of a car
water in oil The smell of anti-freeze at the tail pipe (sweet, sickly smell)
You may have a oil leak, and oil us leaking onto the hot motor making that smell
Check for oil leaks on the Camry. Especially look for oil on the exhaust, as the smell can come into the car.
New car smell? Maybe because of the leather seats (if you have leather seats..)
because oil is refined into gas
this sweet smell sounds like you have an antifreeze leak in your heating/cooling system. most of the time it is the heater core
Grapeseed oil typically has a mild, neutral scent, with some describing it as slightly nutty or sweet. It shouldn't have a strong or overpowering smell.
The sweet smell is caused by antifreeze leaking from the heater core. As the hot air passes through the core it evaporates solvents in the antifreeze which have this "sweet" smell. This contaminated air enters the car when you put the heater on. You might try a radiator sealant additive obtained at any car part store. If you interior carpets are wet then the leak is bad and needs immediate attention.
Yeah it usually does, if you smell something you should go see a mechanic to get it checked out, the oil can catch fire and ruin your engine.
You probably spilled some oil on or near the engine, making it burn when the engine heats up.
The sweet smell is most probably from the glycol in the radiator. When there is a leak or the engine boils then the water/glycol mixture that finds it's way to hot engine parts will smell sweet. (Glycol is a sugar but it is poisonous DO NOT TASTE IT).
