SOURCE: Car Heater smells strange

from he Popular Mechanics site if the smell in your car is like maple syrup:

WHEN: After the engine has warmed or possibly even after it's shut off for a few minutes.
THE CULPRIT: Coolant containing sweet-smelling (but toxic) ethylene glycol is leaking from somewhere. It could be coming from a radiator or heater hose, a failed intake manifold gasket or cylinder head. It might be coming from a leaky radiator cap or the radiator itself, especially if you smell it outside the car. A strong odor inside the passenger compartment probably means a bad heater core.

SOURCE: Heater Core Leaking

you could quick fix! but you will have no heat, 1st under the hood, look at the back of motor, follow all you're radiator hoses, take two hoses off the heater core stick a pipe that is big enough then clamp the pipe down. to both sides of hoses to the pipe you will eventually have to replace heater core!!

SOURCE: 2001 Kia Sephia, electrical problem..

The fuse box may have gone bad and your getting electrical shorting. Check the fuse box under the hood that may have gone bad and may need to be replaced, look for corrosion where the fuse goes into and the wire harness. Don't know if you had your car since new, but there are a lot of cars from the Katrina Hurricane that was under water and the electrical system have major corrosion that should just be showing up now. Good luck and keep me posted

SOURCE: strong antifreeze smell when running the heater in

Usually a smell of antifreeze in the cab when the heater is running is a sign the heater core is leaking. Just becasue you dont see a leak at this time doesn't mean there isn't one. It might small enough that the haet from the core is burning off the leaking antifreeze. I would suggest replacing the core before you get in one day and there is a puddle on your floorboard. Or if you go to a local parts store and rent a cooling system pressure tester, wait until the vehicle is cold, pressure the system to 12 lbs and then check for leaks. Hope this helps you out......

Testimonial: "that is what i also thought, no puddle yet, just waiting. I tried a sealant for now, but will get a heater core"

I smell gas when I start my car and turn on my heater Kia Sephia 2001

I strongly recommend you stop driving this car immediately, the possibility of raw fuel in the engine compartment can be extremely dangerous. It sounds like you may have a fuel leak around the engine bay somewhere and need to locate the source and have repaired.
