Why You Need To Put Holes In Your Jeep

It sounds like so cheesy used car salesman trick, but putting holes in your hood actually has some very real benefits. While it may be easy to bust out the Sawzall and start turning your beautiful rig into swiss cheese we recommend reading a little on the back story and options before you have a did-it-yourself mess.

Why put holes in your Jeep?

To provide the engine with vents. It’s as simple as that. Stock a Jeep Wrangler doesn’t have many vents or ways for the heat from the engine to escape. Sure there are a variety of small holes here and there that do vent some of the heat produced, but not nearly as a hood louver. Hood louvers are typically a sheet of metal that has upraised vents designed to allow the hot air float up through the engine compartment while keeping the majority of the elements out.

By using louvers you reduce the risk of over heating while off roading. Many rigs aren’t able to handle the heat that is generated while rock crawling and heading through good OHV trails. You do not want to be stranded with an overheating engine while out wheelin’.

Venting the hot air with a hood louver is one of the easiest, and cheapest ways to upgrade your Jeep without the need of fab shop skills to complete. The GenRight hood louvers literally bolt or rivet onto the top of your Jeep’s hood and are one of the fastest ways to make your stock Jeep look custom.

You will see a significant and noticeable reduction of the running temperature while off-roading or just on the street. While hood louvers do provide a dedicated solution that removes any heat build up from the radiator, they do not solve over heating problems.

Not All Are Created Equal

There are many hood louvers out there, made of cheap sheet metal that will deform as you rest your elbow on the hood for your new facebook profile picture. Alternatively, there are many other manufactures that would throw a steel louver set on your Jeep and add a ton of weight. GenRight hood louvers have had some serious thought put into them:

  • Aluminum construction is one third the weight of steel
  • .080″ thick high quality aircraft grade aluminum alloy won’t deform under your elbow
  • Multi-piece set to maintain the hood’s structural integrity
  • Can be mounted anywhere on your hood
  • Includes all necessary hardware
  • Jeep vents allow hot air to escape from the engine compartment
  • Cost effective way to make your Jeep look ‘custom’
  • Compatible with anything that has a hood

Where To Put Them

GenRight provides 3 different base hood louver packages for Jeep venting; the long back, short back and long front. Each is designed to vent a different area where excessive heat or pressure builds up under the hood.

Long Front Louver – This wide louver is meant to sit just behind the radiator, and vent the hot air it produces out, away from the engine. As a bonus it also provides an escape for the low pressure vacuum patches that occur behind the radiator.

Short Back Louver – These are meant to be mounted toward the very rear of the hood where they can vent excess heat from  along the fire wall and the engine.

Long Front Louver – Where other vents are meant to cool a Jeep, these long louvers are largely meant to reduce the vacuum pressure under the hood at highway speeds and allow for better air flow through the engine compartment.

    I love my louvers, It made a big diffrence in my under hood temps. After some wheeling I can see the heat rising up thru the vents when parked.

      Yup, there’s no worry about searing your fingers when opening the hood after driving.
