Acid Smell
When I'm going up a big hill and I have to give alot of throttle to my 04 sxt I smell a horrible acid smell. Has this happened to anyone else or does anyone know what could be the cause of this? No smells or anything else at any other time and the car runs fine. Thanks for any help.

How's the battery looking? That's the only real acidic fluid in the car.

And I'm not sure it would smell that bad. I had a battery get chewed by an alternator pulley fan once, and it leaked/splattered acid everywhere. There was no odor. Just a horrible sound.
(Large pot hole, and not knowing another person had forgotten to tighten the battery hold down = Fail)
Could be something catalytic converter related, either too much fuel, or a failing converter. ???

OK....
Or a coolant leak. Could just be spewing under higher rpms, to make it up the hill. Or the load is peaking the temp enough to force it out. May be a head gasket leaking into the combustion chamber, or a cracked head leaking into the exhaust.
Edit: or a simple as the overflow spilling onto the exhaust manifold.

It normally does, but not knowing what OP's perception of acidic is, I'm leaning towards something more potentially consistent with the details given. Just more along the line of throwing stuff out...racer12306 wrote: I thought burning coolant had more of a sweet smell to it.
The only thing that would fog up the window is steam, whether or not it is inside or out, IDK...
If it is overflow from the coolant expansion tank, it may also have ATF mixed in it, with the two smoking when they hit the exhaust.
Douglas, check the overflow on the firewall for ATF contamination. or over full.
Edit: Assuming the car is an ATX...

When i would floor the car up a big hill, occasionally i'd see a bit of black smoke right after it downshifted. Raw fuel...pretty sure it just didn't like my 2.5" exhaust. That and occasionally when you get on it that hard, it sucks up a bit of the oil that has pooled in the bottom of the intake manifold. The oil in there has quite a bit of residual fuel collected in it though.. i always thought it smells a bit acid-like.. I never noticed it inside the car though, just under the hood after i had driven hard.
New Sig Time.

If the cooler in the radiator has begun leaking, it may not be ok anymore. The cooler leak has been a problem for a fair amount of ppl. That is why he suggested to check the fluid.
In what way does the antifreeze look/smell?

Electronics burning can have a strange smell. I wonder if your defrost grid has some kind of short? I don't see how a cat converter, battery, or heater core could cause the REAR window to fog up.

If it is on the outside of the glass, it could be coolant related. Likely all the rear facing parts would have condensation on them, but the only thing you will see from the driver's seat is the back glass.
DouglasSXT, if/when it happens again, if you can pull over, check the decklid/bumper for moisture, as well as under the hood. (If it is on the exterior...)

Not sure how if his defrost grid has a "short" in it, that it would produce fog. Depends on his location I suppose, but then again, is his window wet? How is it getting wet? Rain? Snow? Hail? some sort of precipitation? I'm thinking Bill is on the right track...
Maybe if the OP can describe the smell of the rad fluid a bit more, we could do more troubleshooting. Cause if his rad fluid smells funky as he said, than I'm sure that is probably what he is smelling NOT acid. Or it could be coincidence that his rad fluid took a shit on him as well as his cat? :S

Bad cat converters smell like rotten eggs. I'm doubting that is his problem.

00Neon - A dead short in the grid could cause excess heat, and maybe fog the window up if it was cooler outside. This is just a theory of course, to be honest the rear window part makes this pretty unusual. Def need more details on the window when it happens.
I can't really wrap my head around why you guys are leaning toward a cooling issue. It would take a hell of a leak to get actual coolant condensation on the outside of the rear window, or a ridiculous leak from the heater core to get it on the inside (jk lol!).

Ya, I see what you're trying to say.
Maybe....
The coolant is coming out and as we all know, heat rises, so it rises and as he goes up over the hill he's going through the coolant steam and it builds up onto the car. I wonder if he's getting it on the roof as well?

If that was true, the windshield would never defog/frost.OB wrote:00Neon - A dead short in the grid could cause excess heat, and maybe fog the window up if it was cooler outside.
Colder than ambient objects will fog up, not hotter than ambient. Take a glass of cold water on a hot humid day for example.
Excess moisture coming from the exhaust, or the overflow hitting the exhaust would make things very humid at the rear of the car/sucking into the cowl (into the car). The airflow at rear of the car will draw that moisture to the rear deck, and possibly the window, tho I have rarely seen much get past the decklid.
Until we get better input from the OP, it is all mere speculating...

well, how would rad fluid be able to fog the rear window? IF... the rear window fogging up is in ANY way connected to this acid smell, logic would say that since the only thing to affect just the rear window is the defogger, to start there. I'm just saying.......the acid smell your smelling.....is it only upon going up hills, or maybe if you just gun the motor? What about going down hills? Is your vent to the outside air open or are you in recirculation mode? Do you have any electrical problems like blowing fuses or items intermittantly work? Do you notice any fluids on the ground after your car has sat long enough to cool down?00Neon RCR wrote:OB wrote:Electronics burning can have a strange smell.

Sorry not getting what your saying man about sentence #2 from post #3 connected to my sentence#2. Just trying to clarify some information for better assistance. I was asking more questions to see if I could either eliminate the fogging of the window from the acid smell, or eliminate the radiator fluid funky look from the acid smell. I know (at least here in Az), during summertime, the high heat can cause a buildup of moisture inside the car. Not enough to fog a window, but when you drive, I can see that possibility. Also, I can see, if he has his vent to outside air open, and there is an escape of radiator fluid on a hill climb, he would smell it through the vent. Just trying to help out is all.

Your second sentence basically asked "if the window fogging up even has anything to do with the acid smell" In post #3 the OP said that the window also fogs up (while this "smell" is occurring) So I'm taking it they're somehow related.inthewerks wrote:Sorry not getting what your saying man about sentence #2 from post #3 connected to my sentence#2.
