Water Vapor from Exhaust

[RunningForNow]

Sorry, I know very little about these engines, and I’m still learning about mine, so forgive me if this is a stupid question. I noticed when I started the truck tonight, there was quite a bit of water vapor accumulated on the curb where I parked. The pic shows the puddle, and that was idling about 5 minutes. It’s a 2001 5VZ-FE with 189k miles on the clock. Runs and drives great with no engine issues. Newer plugs, coils, and wires, and TB/WP was just done three weeks ago. Engine doesn’t hesitate and doesn’t feel sluggish.

Is this amount of water vapor normal? (See pic)

Totally normal. All cars do this. When my 4Runner sits in the garage for days at a time it will usually leave a huge puddle on startup

 

[HiLife]

Yup, normal. My 4r would do the same if idled for 5 min or longer.

 

[RunningForNow]

Cool. Thanks for your input. I know vapor is normal, but it just seemed like a lot when I saw it.

Pay attention to other cars, v8’s, as they pull out of parking lots where they were parked several hours, like leaving work. You’ll see water running out the tailpipes.

Water vapor is actually one of the byproducts of gasoline combustion. You combine Gas + Oxygen and you get out C02 + H20. When it is cold the water vapor condenses and makes liquid water you are seeing. If you are seeing this once the engine and exhaust pipe are hot, then you might have an issue.

The chemical process of creating fire creates water, not just "gas" as in a petroleum product such as gasoline.

"Gas" can be just about any fuel: paper, wood, etc.

Yup, totally normal. All of my Yota's seem to have more vapor than other vehicles I've owned for whatever reason.

Only worry if it smells distinctly 'sweet', and your coolant levels start going down.

Yep. Completely normal in wet climates.
