I'm about to pull the trigger on some Hood Louvers in an effort to vent some of the heat that's threatening to melt my truck. I want to mount it on the raised area, in front of the washer nozzles. Then, i'll use a hood blackout to make it a little less obtrusive. I'd go out and measure my own truck but it's at home and I was hoping to get the order in today.

Does anyone know how wide and long the raised area on the hood is?

Cheers!

 

42x34 largest rectangle you can use

 

is that 42" wide by 34" long ? (ie front to back)

 

You could save yourself a lot of work and reduce engine temps dramatically by installing an inline thermostat. Just saying. I'd be concerned with water intrusion with those Lo louvers.

 

This has absolutely zero to do with an inline thermostat This is about venting excess heat from under the hood. An inline thermostat won't prevent my underhood getting so hot that it's melting plastic.

I can put my truck into an overheat condition when towing or climbing. In those scenarios, thermostat is fully open, but the radiator and cooling system is unable to cool the car. When I'm not towing or climbing I see temps ranging from 179-190 with the occasional spike up to 203 (which would go away with an inline mod)

What would you be worried about getting wet on the truck ?

I ordered my Hood Louvre. I'll get it installed next week and report back on temps under load.

 

Plus it would look really cool.

 

Under hood temps have Nothing to do with the running temperature of your engine? Okay, good luck with your project. Looking forward to the pics.

 

Oh dear. This is why I love the Internet.
Go read a book on thermal dynamics and we'll reconvene once I'm finished.

 

Looking forward to OP's honest coolant temp readings pre/post hood vent install. Snake Skin? Only time may tell.

Robert,
What brand did you go with? I was on the RunCool Hood Louvers website a week or so ago, and their install video was on a Disco.
Something I was thinking about also, was either wrapping or ceramic coating the exhaust manifolds. From what I understand 60-80% of the heat comes from them.
From what I researched, water was not a problem, but personally, i will try to keep my coils protected(although they are already pretty protected). After all, the louvers are facing the rear and as long as they are not too near the windscreen, they should create a low pressure area(at speed), whereas too near the windscreen it would have more of a cowl induction effect from the high pressure.
I have also had people shaking their head when I talk of painting the engine black to radiate heat better than plain aluminum.
