I have a Honda Fit 2012 Sport.

Second picture shows a close-up of the left, circled item in picture 1, the fourth picture is a close-up of picture three. Also, would it be safe for those two items in picture one to be sanded down to remove the rust? I wouldn't want to sand the rust down to thin out the metal too much if not necessary, but it sure is ugly like that. Lolz.

That tube from picture three and four, just above the transmission dip-stick, seems to leak every time I drive my vehicle, and lands on the surface below it and just sits there accumulating. Is it the condensation build-up from the A/C?

Thanks.

 

Green circle on the left is your passenger-side motor mount. Green circle on the right is the exhaust gas recirculation valve. Both can be sanded and painted no problem. I can't seem to reference the tube on my car, but my guess is that it's the AC condensation drain line -- and its designed to do exactly what it's doing.

If you want to simply make bare metal look less dirty and corroded, I recommend I use them for so many things, including getting debris out of cast aluminum like our intake manifolds (i was introduced to them through a youtube video of a honda mechanic using em to finish resurfacing a cylinder head at a dealership). Another possible is a brass bristle wire brush paired with running water for a porous surface. I recommend only the pads for non-porous if you don't want scratches but rather a finish closer to polished. It does vary based on the density of the metal.

​​​​​​The link listed is a fair deal, but they're also stocked in big box stores like HD and Lowes, often in smaller quantities. Don't get grease or oil on them as they can transfer it and stain porous stuff, wd40 is a fine lube for a nicer finish on non-porous.

They wear out at a reasonable rate but are prone to getting shredded if used rolled, folded, on sharp edges.

The small tube circled in yellow and blue is a vent line from the transmission. You should not be seeing water droplets coming from that tube. It’s just an air vent. The condensate line for the a/c is located under the car on the right side towards the firewall of the car.

 

I dont know the automatic tranny, but the manual has no tube ​​​​​ I held it in my arms like a baby. Sup with that tube? It seems unlike honda in this eco era to have a vent that doesn't go to a charcoal can or intake duct/plenum

 

Ahh that makes sense. I have a manual too, and was like, where the hell is this tube???

 

Somebody needs to dig in and figure out this mystery tube fiasco. No hole left behind.

 

Like previously said, it’s an auto trans. vent tube. You can sometimes see very small amount of ATF that drips out of it. It’s normal.

 

Hey, thank you very much for the information, folks. It's very informative. Indeed, I have an automatic transmission.

Yeah, that makes sense that it's transmission fluid, because I wipe that crud off where it drips on to and it's really dirty. I've checked a couple of times after driving and the exit of the tube hole has transmission fluid wanting to drip off it.

@Pyts Would sandpaper at a particular grit equal to those pads you linked to?

 

I'm still surprised at the thought that honda would have a vent on their transmission that could spill fluid onto the street under normal operation. An unfiltered vent at that. I'll inquire next time I'm at the dealership.

As for using sandpaper, I'd still recommend the pads that have a thicker scrubbing material. Even if the abrasiveness was a match, paper wouldn't be as prone to get into nooks and crannies, plus 3m doesn't list the grit of such pads on the packaging. 220 sand paper is considered very fine also, but that range goes well into the thousands, all being progressively more fine.

"Sandpaper and steel wool are two different abrasives that will bring a different quality to the surface of a piece of wood or a finish. If I dare make such a comparison, 0000-steel wool is about equivalent to 400-grit sandpaper." - copied from a woodworking forum.

Small packs of the pads I recommended are readily available within the paint sections of home depot and lowes allowing sampling of a smaller quantity of the product without hassle of shipping.

 

Pretty routine stuff, having a transmission vent. And it's not like you're pouring quarts out, the thing only holds a couple. And we should consider ourselves lucky we can even change our fluid. Merc uses a sealed 10 speed on their outgoing GLE and GLS cars. Once they're assembled and filled and subsequently capped with a torque converter there is no way to service that transmission anymore.
