I reject even the hint of overheating...

I fixed the ac on the jeep, workin' good, but the motor seems to get a little hot. I live in Florida, and I refuse to have a car that even hints at over heating. I want to be cool, and for the jeep to be cool too!

So, here's the story. I had to do the "heater core bypass" thing on the jeep because it leaked. I woulda just replaced the heater core, as I do have a new one here, but because it's in the same housing as the ac evaporator core, I did not want to have to deal with recovering it's Freon. After all, I just got the AC working!!!

So I was stinking, I mean thinking. what if I put that heater core somewhere in the engine compartment and run a fan over it! Hmmmm, auxiliary cooling maybe!

Attachment 466765

And wouldn't you know it, it worked. The Jeep now does not even get quite to the midpoint on the guage. Love it. Sometimes it just takes redneck ingenuity!

BTW, just in case, I do have a new fan clutch coming for the mechanical fan in case that is actually the problem. But I sure love having a custom Florida Supplemental Cooling System on the Jeep! If/when I do fix the interior heater core, I may just keep this on in place. Me Likey!

Great Idea. Few folks know that it can be an extra water cooler if it runs warm. Yes, if it's in it's normal position for a heater core, yes the passenger compartment gets hotter than hatties, but could get you where you can get it fixed instead of suck on the side of the hyway, or worse...A blown engine due to overheating...

I know it does not get cold there, but maybe if you fix it for real you should put a switch to be able to turn off the extra cooling on cool days. To make sure the engine gets to the correct operating temp. I know nothing about this, just thinking out loud.

Yep, I got this one on a separate switch so I can control it right now. I've actually got it on a relay, and can easily connect it to ignition power so it runs only when the ignition is on. Or I could make it go on when the temp gets warm too, but I think I'll leave it on the switch. More fun that way. we see, I can always change my mind and change it up!

That's some slick thinking

Cool! :Rofl

Awesome, nice work

Super cooling for those hot Florida days

Yay, Shu's back online. Whew, I know it was a rough one, but you have overcome.

Oh, that reference was about Shu getting though all his technical computer and Internet issues, and back online.

Welcome back Shu! Glad you’ve been keeping the boss straight over there.

Good idea for the cooler, I’ve seen a bunch of different ones. Some folks run stripped down 4WD through the forest and they have radiators and trans coolers plumbed into some unusual places.

Agree with Skeet. I have seen them on roll cages and in back compartments as well.

Growing up in the high and low deserts out west, and been around a few off road desert races, they get right inventive on the cooling. Yes, some use water cooled engines. Especially the racing trucks...and some buggies running the Honda or Toyota engines...

So hot is hot is hot is hot, I can reject overheating, but it is still happening....

I've done some things to try to bring down my engine temps on the Jeep (like the aux radiator), and it seems to have worked, but just for so long. Eventually the temps rise to over 220. It's not over heating, but like I said, me no likey! I want it coooooolererer

I broke down and bought a new radiator and it fixed the issue for good, hopefully. The engine runs way cool. I had previously put in a 160 degree thermostat, and it's now running too cool! Gotta put in a 180, and it'll be fine me thinks!

Circulating water is necessary, no telling what was in the core of the old unit. My Mercedes keeps loosing a tablespoon or two of water but I haven't found where its going. Now you and your engine is Chillin'!
