Does this actually work? I remember doing this at the track while waiting to stage , but, whatever, I was young(er) and really not sure it did anything ...
To be clear, I'm talking about pulling the release, and leaving the hood open an inch and held by the hood lever-- obviously, I'd end up installing hood pins, and I'd only ever do this if running on a trail at slow speeds.
Anyone do this, and does it work? or is this just asking for trouble?
Ok so one time I was driving my WJ and it basically went into cardiac arrest. Oil pressure dropped low as crap and temp went like a rocket. I rolled down the windows and blasted the heat. Barely helped. I pull the hood release and that seemed to help it enough to keep the temp stable. Mind you this was going down a highway at 55. Turned it off once I came to a stop and let it sit. Noting looked weird under the hood and I went back on my merry way. No clue what happened. So moral of the story, it worked for me in an emergency situation. I would never rely on this as a conman practice.
xj's get quite hot under the hood, especially if you're running the a/c while crawling on a trail.
what i've done, and many others have too, was put some spacers on the hood hinge bolts to pop up the back of the hood an inch. this lets a lot of the heat to escape.
i used bicycle rear wheel cone spacers on mine since i'm a bicycle mechanic, but stack some washers or cut some tube to make it work.
works like a charm for me.
i also add water wetter in my rad too, and a larger trans cooler.
+1 Got mine up 1/2" and removed the pad. I did mine after my HCV self destructed. Hoping to keep the temp of the heat sensitive components down. Definitely lets heat out.

What's water wetter?
anyway, just exploring. I goy a set of daystar hood louvers (I like the look-- they're very similar to the ones on my SRT), and going to drill them in next weekend :-)
I forgot to mention that I also removed the rubber gasket below the cowl. I then used a ballpeen hammer to bend that shelf down a bit at a time until I had an even 1/2" gap all the way across.
water wetter, it's a super coolant additive that you add to your 50/50 mix. works wonders especially for you guys in the extreme hot climates.
Used this for many years in my race cars.

popping hood to alleviate overheating?
