AMCJeepMJ Posted February 10, 2013 Share Posted February 10, 2013 Looks nice. What did you use to seal it against the hood so water does not get in? Also, any interference with the wipers when the hood is raised? Link to comment Share on other sites More sharing options...
jeepsouth Posted February 11, 2013 Share Posted February 11, 2013 I have to use one prop rod hole lower now ,or remove the passenger side wiper arm. I used some heavy duty stick on foam sealer i got at work. There is a strip of the same sealer stuck to the hood that runs parallel to the opening at the windshield to stop any water that might get under the cowl opening. You have to look in the opening to see it. I have more pics than i posted that show this. If anybody wants to see them i'll send them. here is another pic.

Did you use any kind of mesh or grating on the back side of the cowl to keep rodents/leaves/birds/elephants out, or is it open? Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 11, 2013 Share Posted February 11, 2013 I have to use one prop rod hole lower now ,or remove the passenger side wiper arm. Yes, that's a problem with cowl-type hoods. I just leave the right wiper arm off most of the time. Link to comment Share on other sites More sharing options...
jeepsouth Posted February 11, 2013 Share Posted February 11, 2013 Did you use any kind of mesh or grating on the back side of the cowl to keep rodents/leaves/birds/elephants out, or is it open? I left it wide open. Link to comment Share on other sites More sharing options...
jeepsouth Posted February 11, 2013 Share Posted February 11, 2013 Yes, that's a problem with cowl-type hoods. I just leave the right wiper arm off most of the time. Yeah i could do that also ,but it's easy to remove the arm. Remembering to do it is the hard part. Link to comment Share on other sites More sharing options...
vaquaro Posted February 11, 2013 Share Posted February 11, 2013 I feel like the location of the vents may change the functionality. That being said, I think none of the vents are functional and are only sold as snake oil cooling. Aesthetics value only. There's a pretty good evaluation of vent positioning on the "go Jeep" site which documents under hood temps at low & high speeds ....Worth the read :thumbsup: Link to comment Share on other sites More sharing options...
shawn Posted February 14, 2013 Author Share Posted February 14, 2013 Looks nice. What did you use to seal it against the hood so water does not get in? Also, any interference with the wipers when the hood is raised? i really don't see any reason to worry about water getting in. the only reason i keep the hood on at all in the summer is so tree branches don't grab under-hood wires and hoses and things on the way by. (and i live in a rain-forest). water shouldnt harm anything, considering quite often we will be speeding through huge puddles and lots of water is flying around under the hood then.

jeepsouth Posted February 15, 2013 Share Posted February 15, 2013 I have been getting some water under the hood ,but no issues yet. Will be looking into what it will take to reduce ,or stop it. Link to comment Share on other sites More sharing options...

tugalo Posted February 16, 2013 Share Posted February 16, 2013 I went to the local used appliance dealer and looked at his second hand dryers and ranges till i found some vents that i liked. He sold me the entire back panel from an electric dryer for $1.00. Some careful measuring from underneath the hood to avoid the braces, some nice slow cutting with a jig saw, some thin shims to make the metal flush with the hood metal which is a bit thicker. riveted them in place and filled the seams with body putty.

AZRick Posted July 13, 2013 Share Posted July 13, 2013 I feel like the location of the vents may change the functionality. That being said, I think none of the vents are functional and are only sold as snake oil cooling. Aesthetics value only. Just my .05 cents worth, I have nothing to gage the effectiveness of the louvers I installed in the hood of little beast. I installed the same louvers in the hood of the 2500 Ram I had, there was a way to gage that. Previous to the louvers the transmission temp pretty much stayed in sync with the engine/oil temp as the truck has an engine oil to transmission fluid heat exchanger. After installing the louvers the transmission temp while on the highway hovered at around 150 degrees. The down side was, the louvers reduced under hood temps enough that the fan clutch wouldn't kick in and the AC didn't do well in stop and go city driving. I'm not so sure the louvers are making the same type of difference on the little beast, the air flow dynamics under the vehicle are completely different with the JCR bumper installed. I think removing the stock bumper and fairings increases the air pressure in the engine compartment. With louvers in the hood in this situation, air is going under the bumper, up through the engine compartment and out the louvers effectively reducing airflow through the radiator at highway speeds. My support for this theory, 110 degrees OAT, engine temp at cruise on the freeway is 220 (digital gage). After exiting the freeway, on the surface streets engine temp hangs around 210 and the AC output temp drops from 40+ to 38 (at which point the compressor cycles) i.e. more air is flowing through the radiator and condenser at lower vehicle speeds. But they look cool :rotf: and should work well when wheeling. Link to comment Share on other sites More sharing options...
RockMJ Posted July 15, 2013 Share Posted July 15, 2013 Another option for anyone curious would be Hyline Off-Road's louvered hood vents. I have had these on two of my Jeep's here in Florida and they definitely work. Front vents are facing forward to pull air in and help push the hot air out. On hot 95+ days I saw a 10-15 degree drop in temps with the AC on. Might not be typical for everyone as my cooling system was upgraded to combat the heat down here. Anyways, here are a few pics Pricing wasn't too bad, IIRC around 150$ or so. Hope that helps RockMJ Link to comment Share on other sites More sharing options...
