Condensation? Water Leak

Just noticed a water leak on the driver rear door side.

It is water, I didnt see any condensation lines.

 

Muffler weep hole?

 

I’d definitely say that’s a muffler leak. Mine is doing the same thing. In fact, when it got below freezing here, I looked under my truck and saw an icicle hanging directly from the muffler. lol

 

There’s a weep hole in the rear of the muffler. It’s by design

 

What you mean a water leak? Water isn’t used for any fluid in your truck. Aside from possibly the windshield wipers.


That is called condensation. Water is a byproduct of internal gasoline combustion engines.

 

Well technically he’s right, as are you, it is a water “leak” from condensation from the exhaust. It is a designed”leak” though.

Also, just for clarification, the water from the exhaust comes from 2 sources. Condensation in the piping, and it’s a byproduct of the catalytic converter process.

 

The water comes from the water vapors that are produced as a by product of gasoline combustion. The metal exhaust pipe is cool. Exhaust is warm and full of moisture, hence the condensation that is produced. You can completely remove the cats and still get water out of the exhaust.

 

Speaking of condensation, what is the normal amount that should drip from the AC system when it's hot and humid outside? Let's say when you stop for fuel on a summer roadtrip thru the South.

My 2023 Tundra seems to drip excessively compared to other vehicles I've owned.

 

There’s no standard amount. It’s all dependent on all the variables. Outside temp. Humidity. Ac setting whether on fresh air, or recirculate and the temp it’s on.

 

Thanks. That's what I figured...too many variables to quantify. I'll assume it's operating normally.

 

I’ve always lived in south Louisiana. Humidity is part of our everyday life. I guess you just don’t pay attention when every single vehicle is dripping water from the ac mostly year round lol.

 

Yeah, I live in dry Colorado, so I was a little shocked when I first saw the puddle under my truck at a gas station in Florida. Then I looked around and saw that every other vehicle at the station had a similar puddle. LOL

 

Needs a bigger hole.
