Crazy and simple cooling ideas that came to my head.

[ReconH3]

I got two crazy ideas that came to mind when I was working in my truck.

First is real simple and it takes like 30 seconds to implement and is reversible. Simply remove the rubber seal at the end of the engine bay. The one closest to windshield that seals hood when closed. I remember seeing hot rods with spacers to do just that. This could be a quick fix if your out on the trail, but still a long way from civilization, and your having overheating issues.

Second requires some PC fans and either a temp switch or a manual switch. You would install them inside the faux intake covers. Depending on how much air you want to move, you would enlarge the portion that lies in the engine bay. This wouldn't make a huge difference, but if you combine it with a working hood vent, it could be enough to keep temps from going up. I'm going to look at this possibility and see what I come out with.

I've started increasing the size of the vent holes that are already there. This will increase airflow without doing a huge hack job. I could probably go up another size but I'll start with that for now.

What size drill bit (im assuming that what you are using) are you using for this?
Also is there any room to increase the hole that feeds into where the air holes are, not sure if it will make a difference.

I had noticed when i had my covers off for something that a lot of heat escaped through those holes and if there is a quick way to increase the airflow through there and keep it looking stock im all for that.

I used a unibit so I have no clue. I can check later when I get home.

You can hack the whole corner off where I drilled the holes if you want. I'll see first how it works like this.
You could also increase the internal window out to where the "A" has been written with a yellow grease pencil (see in first pic). I'm just going to drill more holes along that flat wall so as to not compromise the integrity.

Very interesting, I didn't know that air escaped out the drivers side "vent". I saw that the passenger side "vent" could be used for an intake snorkel, but if it exhausts engine heat I would prefer to use it for that.
For dropping engine temps I am going to remove the radiator from the transmission and run a stand alone oil cooler with a cold bypass. I think that the engine radiator not having to shed engine heat AND 200°+ transmission fluid will help get some thermal load capacity back for the radiator. We shall see. Looking forward to your results.

Pretty neat idea I might have to barrow this ideas for do the same to panzer [emoji106]

Tried to figure out a way of putting a 3" 12v fan inside to help extract the heat, but it was a no go. I don't want to go smaller simply because it becomes inefficient. I guess an alternative may be to put 2 or 3 2" fans next to each other. I May resort to just putting it in the engine compartment, but that will be another day.

I like where you're going with this!

A computer fan won't move enough air to make any difference and probably becomes a flow restriction at 5-10 MPH.

You could try squeezing one of these in... https://www.sparkfun.com/products/11270

For any fan to make a difference in engine space temp it needs a capacity of hundreds of CFM. And basic fan ratings are based on virtually no losses/resistance too. Functional louvers + electric fans are probably the best bang for the buck for low speed cooling.
