I installed the Genright hood louvers about four years ago on my tj. You can definately feel the heat come out. I have all five of the Genright louvers installed.
Does it remove enough of the heat? I don't know but it makes me feel better. The radiator temp is controled by the thermostat which is monitored by the computer. So if you change the thermostat it will throw a check engine light. Ask me how I know 🙄

Thanks for the info.. I have already installed a 3 core radiator and I still have heat issues. I'm hoping I'll actually be able to run the A/C in the summer on the high way. Have you had any issues with water coming into the engine compartment? I guess all the electrical is sealed for the most part. I just don't want and issues. How challenging was the install.. I'll admit I've never cut holes into a perfectly good hood, guess if I mess up there are plenty out there.

As far as water into the vents. If I'm that deep in water I'm probably in trouble anyway.

I've got the factory TJ hood and installed (mid 90's I think) Pontiac Grand Am hood vents. They look pretty good and seem to help a bit. I've had cooling issues with my 2000 TJ, 4.0L and 3 speed auto trans and have tried many things to help. My problem was idling, in gear, in hot weather so my problems may be different than yours. I've tried Griffin aluminum radiators, electric fan, and removing my aftermarket trans cooler for better air flow. The best combo so far has been to replace the factory 5 blade fan & clutch with a factory 7 blade fan & matching clutch, factory style radiator (from Napa) and the hood vents with the large trans cooler installed.

Good info.. I also have a 2000, 4.0, but MT. After I install the hood louvers I will see how it's cooling, then try the 7 blade fan.

Thanks much!

As far as water goes, I've got a "cold" air intake and the filter is almost under the passenger side vent. I've got an Outerwear filter cover that's supposed to be water resistant. I haven't had any problems with it.

Edit) Looks like I need to repaint the vents again, unpainted they're white.

Looks like a clean install. Looks factory. I'll be getting the poison spyder louvers in May, I'll do a small write up when I do it.

Thanks again for the pic.

Nice.. How challenging was the install? Any pics to share..

Thanks Mark, Is the cooling any better for you?

It runs the same temp but cools down way faster when the fan starts. Mark
