any body add louvers for better cooling( they are done PICS)

I am thinking of having louvers( I hope I spelled that right) put into the hood of my flat fender to improve cooling. Has any one done this? did it actualy improve your cooling? got pics? where can I get this done?

Another option is to use the plastic louvers off of another vehicle, like a Grand Prix or 5.9L Grand Cherokee. I found this pic on a BB, these are louvers from a Grand Prix. They are plastic though so they might look kind of <IMG SRC="smilies/rainbow.gif" border="0"> on a flatfender. It is getting hard to find someone to stamp them into your hood, try the hot rod guys around your area. If you are having cooling problems you can always cut out the inner fenders too.

I hate to cut the fender wells out because they do a good job at stopping mud from being flung into the engine compartment. Thanks for the idea, ill start talking to some hot rod guys. Any body else got some pics and or personal experience. <IMG SRC="smilies/jeep2.gif" border="0">

A buddy of mine has them in the hood of his CJ5 and Scrambler. Do believe they cost around $1 per louver. Should help cooling at idle quite a bit letting the heat rise

i just used a couple of cj vent grills and cut rectangular holes in my hood. i put one on each side and they don't look too bad. cheaper and easier than the louvers.

I've been thinking of doing something like this, too. Friends have done it and swear by it..

Anyone know where a guy could buy some reasonably priced louver punches for the DIY-er?

I'm not too familiar with how louvers are punched, so I may be talking out of my @ss here, but.......I've seen it done on tv, and the machine they used was a pretty large set-up. It wasn't just a punch type of thing you could get for fairly cheap. Just an FYI. Good luck.

For my XJ cooling was a nightmare because of the V8. I cut some holes in the hood and they hellped greatly. To cover the holes I just got a set of CHEAP vent grills from the hardware store. If you are interested in a nicer look hit the boneyards.

When looking at scoops and louvers remember that you want something to let air OUT not in. Air flow cooling problems come because the engine compartment is not allowing enough air out and getting packed with heat. This stops the air moving across the raditor from having good flow. The other down side is that the air you suck into the engine is now hotter and will cause the engine to make less power and runn hotter. Plus you have to work it harder because it is making less power. Old 280ZX's have a cool NACA style scoop that can be turned around. Look mostly at imports, they seem to have the most choices.

I was thinking of dies/punches that could be used in a hydraulic shop press. I've looked online but couldn't find anything other than $1k dies for $10k machines to do the pressing.

Great if I wanted to knock out louvered hoods all day long, but I don't. <IMG SRC="smilies/biggrin.gif" border="0">

the best way, is a scoop that is open front and back so that air that is forced though it by driving will create a venturi efect and pull air out of the engine area.

A guy I knew was on a trip to the 4corners area and his 3.8 buick in his toyota 4x4 kept overheating (hauling a camper) so he stopped at a place in some little town and two hours later had alot of louvers put in the hood. It fixed his overheating problem and looked pretty good.

BTW Cruisers have them stock on the back corners of the hoods.

Thats great.... especially when it rains

<IMG SRC="smilies/eek.gif" border="0"> Facing backwards is best because the air flowing through the rad then carries over the engine and out the hood.

i talked to a local hot rod guy about 2 weeks ago he gets $1.30 per louver and you have to sand the paint off before he will do it.
