I've searched for this for awhile and I haven't come up with anything. So forgive me if this is already out there.

At a stop I notice my 03 Evo VIII has "heat wave" appearance coming out of the hood vent. The temp gauge is reading normal. This happens no matter if I'm driving hard or normal. Is this something I need to worry about or is this normal.

Thanks for any info on this.

 

Nothing wrong ... that's why they call it a Heat Extractor!!

 

Your engine will get hot when it gets up to operating temperature. The hood vent is there to release this heat rather than cook everything under the hood. Simply normal.

 

To reduce the heat wave you could have your exhaust manifold coated to retain heat.

 

lol

 

That's what the vent is there for...

 

Thanks for the replies! Sometimes I get paranoid about these things. Now I can sleep at night.

 

Now u can toast bread in a nick of time...lol.. very normal all evos do it.:

 

i asked the same question i never got the heat wave thing until i installed the red and took off the heat shield now i get it all the time

 

Haha I love how you refer to it as the "heat wave" I love seeing the waves of heat escaping out of my hood btw

 

well the heat shield is going to retain most of the heat. but yea, very normal...lol

 

I was out camping once and cooked eggs mine. I thought it was a grill....but guess it a heat extractor?? either way the eggs were good.

 

Just be glad we have the hood vent so all that heat isn't trapped inside the engine bay! Getting your exhaust manifold coated really does help lower underhood temps though.

 

the heat wave is totally normal don't even worry about it nor mind it

 

if you look at other cars you can notice it too on a hot summer day.
Just more pronounced in the evo with the hood vent and they get a little hott cuz the turbo

people always comment about that when in my evo.
