If you smell gasoline inside your car while you're idling or driving, you probably have a fuel leak somewhere under the hood. If you only smell it while idling, it is probably leaking somewhere between the fuel tank and the engine - wind passing through the grill pushes the smell out behind the vehicle instead of into the cabin. There are several different places fuel can leak from. A leaky fuel line or fuel filter would be the most likely sources, but occasionally fuel tanks can leak from damage or seals. Either of these would be reason to get your vehicle to a mechanic as there is a huge potential for fire. If you only ever smelled it once, it may have come from some other vehicle or a fuel station.
Electrical problem... have a professional diagnose problem ASAP!!! If you do not fix, your car may have a fire!!!
You have a serious safety problem or a engine control problem. See a technician immediately! 3 minutes
The Catalytic concertor smells like rotten egg throughout the exhaust system or rattling from underneath your vehicle .
Allmost certainly a head gasket on that side.
If your vehicle shakes and smells like gas then you have problems other than low transmission fluid. Shaking and fuel smell indicates that all of the fuel is not being burned properly, and the engine is not operating as it should be.
You have a fuel leak somewhere. Have a trusted mechanic find it and repair it as soon as possible. The vehicle could catch on fire.
Olfactophobia - fear of smells
I really don't understand what you are asking. Anti-freeze is leaking because you have a leak. But you already know that. If you are smelling coolant at the exhaust, then STOP driving this vehicle. You have a blown head gasket or a cracked head, or both. Serious engine damage will occur if you continue to drive it. Anti-Freeze smells sweet.
