2011 Tahoe...Clear fluid leak behind passenger side front tire

[Glancing43]

Newb here. Have a 2011 Tahoe LT with 135,000 miles. Noticed white smoke coming from under the hood the other day with a bit of a smell after turning it off. No engine overheating.

Popped the hood, couldn’t see anything from the top down. Found a leak seemingly coming from a hose behind the passenger side tire. It’s clear fluid. Water? Wiper fluid? I put some cardboard under it to see and snapped a few pictures.

This all started after a recent oil change and 2 tire replacement. Just a coincidence? I have no clue. I’m not a mechanic and not someone who would try to fix anything myself. Just wondering what I’m looking at here. Any help or suggestions would be greatly appreciated.

Thanks!

Condensation from the AC Accumulator? Washer fluid is on the other side.

As James stated the likely suspect is the accumulator but it won’t usually drip on anything or have an odor. If you keep the AC off for a bit before parking does it still show up overnight?

If your tahoe has a skid plate it’s likely just condensation from the A/C compressor. My 2006 6.0 Denali has a skid plate and the condensation catches in the skid plate. It drains down below the starter and comes out right behind my front passenger side tire. I usually see the puddle right near the cap of the running board where it meets the fender.

Appreciate the feedback. It definitely smells like something is burning when I turn it off. I was at a red light the other day and there was so much smoke, I thought it was on fire. I reversed into a grocery store parking lot. Really strange. I know that’s not normal.

Yeah I definitely see puddles from the A/C, but the smoke and smell are new. Like I said in another post, there was so much smoke I thought it was on fire. Maybe something is blocking or redirecting the condensation?

I’ll test it out and see. Sometimes it creates so much smoke you’d think I’m burning the tires out. It’s pretty weird.

welcome.
The clear fluid is condensation from your a/c, that’s where the drain is, you just haven’t noticed it before. The smoke is from the oil change place getting oil all over the exhaust manifold as the fill is on that same side. It will stop, the smoke, as soon as all the oil is burned off, to be sure make sure the yellow dipstick is pushed all the way in and the oil fill cap is installed and tightened.

The condensate from the a/c drain will not stop until you stop using the a/c.
the a/c drain is right there front tire inbetween frame and fender liner.

Thanks for the post, I’ll check all that today and fool with the A/c some.

Just an update, still getting a smell and about 15 seconds of minimal smoke coming out above the drivers side headlight under the hood on occasion.

I understand some oil could’ve been spilled during the change, but shouldn’t it be gone 2 weeks out? Still has a slight smell, not as severe. All caps and dipstick are tight. Don’t see any leaking other than the a/c condensation.

Give it another week or take it to get checked out and quit bothering you all?
