Some people say that the smell of hot antifreeze smells like mold. It could be possible you are smelling the antifreeze from the engine.
Well, the smell could be from a spillage, which when your moving goes to the main petrol tank. another explanation is your mum.
because it's moldy
If your going through coolant then you have an internal head gasket leak you smell coolant because its getting into cylinder and burning
Check your cabin air filter.
i believe your heater core has died
Check for oil leaks on the Camry. Especially look for oil on the exhaust, as the smell can come into the car.
Your gaskets are leaking and you are leaking antifreeze inside the manifold. Same thing happened to me on my silhouette and cutlass. The problem is the orange anti-freeze eats the gaskets. Will cost $2,000-to-$3,000 to fix. Sorry!
Food having a dank odor would most likely smell moldy or old.
Either a leaking heater core or a plugged A/C evaporater drain. You can smell the fluid to determine what it is. A/C condensation smells like water/moldy water, coolant doesn't smell like water.
If you smell antifreeze, there must be a leak somewhere. Have the cooling system pressure tested.
If there is an oil leak inside the engine compartment of the vehicle. The defroster could have some of the smell go into the cabin of the car. The engine should be checked for any oil leaks.
soak it in soapy water overnight.
