So, I recently got some hood louvers to help cool the engine down. My question is which direction should I face them? Do I face the opening forwards or backwards? Any suggestions would be appreciated.

 

I would say forward to pull air in to the engine bay

 

open back to have a good exit for the air thats already pushed into the bay. having the exits back there will be a good exit point for the hot air.

 

The '98 5.9L Grand Cherokee came stock with louvers in the hood. If you look closely, they face rearward to let air out.
Here's the louvers removed, with drip trays:

And as they came installed from the factory:

 

I actually have 3 of them. I have put 2 towards the front and 1 towards the back in the middle of the hood. I was thinking of putting the 2 up front facing forwards and the back 1 facing rear.

 

This is the ones I got. I actually put them on reverse of the picture.

 

theyre supposed to face to the rear

and the 5.9 louvers are non functional FWIW

 

If it were mine I'd have them facing rearward to let more hot air from the radiator/fan escape.

 

Actually, they did let hot air escape, and had rain drip trays. So they were functional.

 

ahh I must have misread somewhere

 

Where did you get them? I want to do something like this on mine.

 

Polyperformance.com they had the best price I could find.

 

Sweet. Thanks.

 

No problem.

 

Have you seen the ones from quadratec? They aren't too bad. I might get those.
