You may have a oil leak, and oil us leaking onto the hot motor making that smell
i believe your heater core has died
No. All you get is smoke and steam. Not smoking stops the smell. Running water like that waste water as well.
You are probably leaking anti-freeze
It is possible that the hot water coil is leaking, and the cold air running mixing with hot damp air will cause the humid smell issue.
try shampooing the seats & rug in your car..
You should not drive a car that is running hot,because you can lock up the engine.
Your car will not neccessarily smell like Antifreeze if your water pump is going, in my personal experience it sounds like your HEATER CORE is shot. That is what usually makes that smell, unless you spilled some on the engine. Also, if the water pump was going the car would run hot and/or overheat.
Generally a burning plastic smell in a car indicates wiring getting hot enough to melt the insulation. This is something that should be looked at immediately to prevent a fire.
yes
change the thermostate
sounds like it could be a head gasket is leaking coolant into one of the cylinders also could be the computer holding a fuel injector on constantif you smell raw gas and lack of power
If the Car is taking on the smell of gasonline while on and running it usually means that the car has an exhaust leak. more than likely around the headers. I would have the exhaust system checked out.
