Hi all,
I've had my 2009 G37x for about 18 months now and this winter I started to notice excessive steam coming off the radiator area when driving in wet conditions......to the point where it looks like the car is overheating. The temp gauge stays normal. I brought it to the dealer yesterday and everything checks out ok, no leaks, fluid levels fine.....they told me this was common with the G37s.......seems odd 1) that I just started noticing after 18 months, and 2) that that much steam is deamed as "normal".

Anyone else have the same problem? Thanks

 

what happens when you put water onto a hot piece of metal? it starts to steam

 

thanks....

Seriously though, at stops, people have rolled down their windows to tell me something is wrong with my car it's that bad......I'm talking about an abnormal amount of steam.

But thanks for your input

 

I've had the same thing after the car wash. Nothing to worry about!

 

Yes, it's normal. Happened on my 07 and now on my 10.

Looks like the car is overheating.

 

its normal. the first night i picked up my car was a little rainy........when i got home i saw the steam and freaked out

 

do you have an explanation why this never happened to any other cars I've owned? i understand your concept, but how come you don't see every car on the road looking like a steamboat when it rains?

but to the OP's question, yes, I guess this is deemed "normal". i had the same question in December when S. Cal was hit with record rain. There was so much steam you'd think my car is on fire.

 

I called the dealership on the way back the first night for the same issue. Its normal. I am assuming the culprit is a badly designed guard to channel water away.

 

Even though I experience this in past with my 08 & my 09, every time it happens it still freaks me out a bit.

 

I think its cool

 

Why is this a problem?

 

yeah it scares the **** out of me some times too, but i keep watching that temp gauge

 

Sounds normal to me. Happens to me in my coupe too lol.

 

It's totally normal. Many cars do this with similar radiator and channel designs. Plus, our engine runs hotter than a Donkey's a$$ in pepper patch, so don't worry about. Worry about things like your engine eating a quart of oil every two weeks or if your engine starts leak things all over the garage floor, or if the valve train starts to sound like robot orgy, or if the car fills with water one day after a car wash. now THOSE are actual worries.

 

I got this too after car wash. It seems like the grill doesn't channel the water away. I also noticed that there is nothing behind the chrome grill to channel or block the water. AS long as it doesn't damage the radiator, I guess it isn't a big issue. I live in Los Angeles so I don't expect to have too many issues with it.
