Heat extractor

[Loki-GT]

Good for you...

The statement meant to be driven refers to someone that actually puts miles on their car instead of acting like it's a museum piece. In no way does that infer it has to be a daily driver or driven in bad weather like snow. Most of our cars will NEVER be worth anything in our lifetime.

Take my words and construe them to your own interpretation. That's what people usually do on forums right?

I don't know a single person who keeps theirs in the garage for occasional use because they think it might increase in value.

There's a few drops of water after a wash job, but that's it. Nothing significant, but I also direct the stream away from the vent opening when rinsing.

I drive mine in fair weather mostly because I like to keep the car clean, and DIB shows dirt fast. Oh and the black wheels!

Thank you very much [MENTION=16083]GTBOB[/MENTION] That’s the sort of answer I was looking for. Merely looking to learn, that’s all.

I work on computers and servers all day. Hence the tech side of me wants to understand how this works. That all...

Yeah, but what makes you think that those vents (with, or without them) stops water from entering the engine bay..? Driving in rain at 60mph and having a massive hole in the front of the car (front air dam) is the same thing, as those two small opening in the hood..

Heck, you don't even need a hood for your engine, it is waterproof and the hood is there to aid in safety, aerodynamics, heat extraction, etc... not to keep your engine dry.

The only thing that sucks about exposing engine components to water is rust and torque. If you ever need to take a bolt off that's been exposed to that, it might require a little extra effort lol.

Just to follow up on this and zombie this thread from the dead, I've found that if you don't garage your car and/or have a waterproof cover, during rainstorms a good amount of water has the potential to get under the hood and between the heat shield, if you do what I did like a numpty. At least according to my experience while the car was still pretty new to me. Probably not the only one this has happened to, but I don't mind admitting my mistake for the benefit of other readers:

I was unfortunate enough to open my hood after a fairly substantial rain, yes, like an idiot, and made my situation much worse than I assume it would have been had I not opened the hood for another 24 hours or so, or some period of time that would have reduced the residual rainwater in and around the hood vents. So, about 4-6 weeks after bringing her home, like a dummy I forgot about the heat extractors and popped the hood after the rain stopped. It pretty much poured out into the back of the engine bay, I mean we're not talking buckets, but it wasn't just a few drops ether. There was a noticeable stream in my experience.

As somewhat of an aside, I did notice some barely visible line of water staining on my battery shield cover that I hadn't noticed on the lot which I presume got there before I owned it, though it could also have been something that occurred post-purchase, it's hard for me to say to be perfectly honest -- I noticed a slight discoloration going across the battery shield, which I have worked to remove with some elbow grease, but I think I can still just about see the faintest of outline of where it was.

Or it could just be in my head, but there was definitely some water/moisture staining on the battery cover in the same place where water came down onto when I opened the hood after the rain. But I digress, my apologies.

So yes, I was lucky to have personally confirmed that the water gets in trapped behind the heat shield, but only if you induce it by opening shortly after a rain. I quickly tried to soak it all up with rags, and then left two thin rags on either side to catch any additional runoff while the car sat in an effort to dry it out as best I can.

Nonetheless, it doesn't make me feel confident that there won't be some type of damage or at least unwelcome consequences of having soaked the heat shield as I did -- i.e. rusting of the hood in behind the heat shield in the dark depths of the underside of the hood that, if you're like me, rarely or if ever sees the light of day. That said, that's going to change as I'm gonna spend the time and take down the heat shield to reveal if there has been any damage or funny business that's gone on due to the unfortunate series of events I put myself into. Definitely need to take a peak before the warranty expires in November 2019.

TL;DR: Garage it when it rains; if no garage, definitely get an outdoor, waterproof cover and make sure it's on when it rains. Lastly, don't open the hood after it has rained or you'll be leaking rainwater up under the heat shield and toward the back sides of the engine back much more than if you had let the hood completely dry 100% on its own after a rain.

P.S. This was just my honest experience, obviously it was a mistake. I can own up to that. However I do hope that by sharing my little anecdote. it may be able to help someone in the future from doing same without thinking. Growing pains, new car learning pains, c'es la vie...unfortunate, that's all.

Interesting. Thanks for sharing...

I've had 0 issues with the working vents and ram air in my aftermarket hood. And I do drive it in all kinds of weather. I have photographic proof right here:

On my '18 GT, the hood vents/extractors have a piece of molded plastic directly under the external vents, with an air gap all around that allows the hot air through and out, and partially obstructs water from entering. Direct water could get through the air gap, but most water would likely be contained in the molded plastic piece under the external vent.

The vents on the '18+ are very different than '15-'17
