Hey thanks man these Jeeps run hot as heck. My jk has a 3.5” lift, adjustable track bars, I’m trying to do this work to keep it. I’m a mechanic and work on heavy equipment and do all my own work including the lift. I appreciate this.
Thanks for the advice on the radiator cleaning stayed up last night to clean it , took the Jeep out for a test ride this morning the temperature stayed cooler than before.
awesome! It’s amazing how dirty they get! And then because of the way they are washing the jeep and spraying it from the front doesn’t get it all out. Makes a big difference if you like playing in mud! But thank for the support man!
Thanks for this video. My readings are spot on with him how you describe and I’m always monitoring it. I’ll definitely be cleaning mine out once these Texas temps give us some relief. Keep these vids coming.
That’s awesome! I’m glad that you were finally able to fix it! This is all my jeep has needed. But I don’t know how many people think to do it! They get so plugged up offroad.
Searching TH-cam for temperature issues with my 2017 Sahara. Fan is running full speed constantly while driving. At park, it slows down. But the temperature gauge is at half 99% of the time. I’m going to try your advice in cleaning out the fan. Appreciate the video.
Thanks for the support Brett! And yes, it really makes a big difference. I was surprised how much came out of mine considering I avoid mud. The bottom 1/3 of the radiator was nothing but dirt and mud. Needless to say the radiator has so much more air flow now and runs a whole mess cooler.
Yeah I bet! We have a lot of road construction going on so I bet all the dust is caked in there. I know you have to have some construction going on in Texas ☺️
My understanding is that the 3.6 cooling system is made to run hotter than the old style systems. 225 here is ok. This is why it's so important to run the correct coolant.
Exactly. I mention that in the video. Definitely designed to run hot. But that extra heat also shortens the life of other components. So keeping as cool as possible just makes everything happier. Jeep doesn’t care if things fail prematurely because they are out of warranty at that point.
JL fixed some of those heating issues, mine never goes higher than a little below halfway and the JL front bumper allows my warn winch to stay low recessed in the bumper I find it funny when I see those videos Quadratec and others put out when they add a high mounted winch, baja large round lights mounted on the bumper bar and angry grills, all that covering up air flow, then they put out another video talking about improving air flow. all that for a circle of Money, never ending spend cycle
Exactly! And yes, they definitely improved the system. But at the same time they still rub VERY hot for emissions. The “halfway” mark on the JL is still up to 225°. Crazy how hot these engines run these days. Mine was up over 230 and sometimes as hot as 237 at times. Not an emergency…but I wasn’t comfortable watching it. Crazy.
@@WarPaintOffroad I'm debating on opening my hood louvers on the JL since we do get a lot of rain here in Louisiana, that's the only thing holding me back the videos I see of people in desert states say they do it because they don't have to worry about rain, so that makes me think that rain will be an issue
I tried installing a cooler thermostat in my 04 rubicon and it threw a check engine light for not being up to operating temperature. I think pre 03 you can get away with a cooler thermostat to help the 4.0s run a little cooler. Once they went distributor-less ignition a lot changed.
Yea. They also had a mechanical fan. That’s the big thing. That fan was on if the engine was on. So when they went to an electric fan….it still allows the engine to come up to temp. The older style mechanical fans were the engines that would run cooler with lower thermostats. Old enough and they didn’t get check engine lights for that stuff. I actually have a lower thermostat in my jk. It needed a new one so I figured why not. The factory opens at 203° mine opens at 180° and it makes no difference. Damn computers..lol
@@nickburns5571yes! You are right! I definitely wasn’t thinking clearly as I have worked on them and removed them…what a PITA. Either way though, they have a much less sensitive electronics system. The electric fan in the jeep is a resistor fan. So still some major differences if the jk 3.6 vs. a tj. You really can’t compare them to the way they operate. It’s crazy to me that the jk 3.6 fan doesn’t even get to its highest speed until 230°. I feel like they should never even reach that to begin with…let along go above that as the fake tries to cool it down. Wild.
Haha. No need to apologize! Thanks for the support! In just a couple weeks the first build on the TH-cam channel will start and it’s a BIG one. Stay tuned. Going to be a really awesome budget friendly build showing how to ton swap and set up a really awesome suspension.
I am deeply considering a video blog for this build, but I'm not an in front of the camera kinda person. (I have a face for radio) all kidding aside though it would be a good one to do it on as it's going to be an extremely radical crawler on a shoestring budget. So far jeep and axels I'm into it $1000 by all said and done I'm hoping to cap out at $2000-$2500 finished.
What size tires and lift kit are you using? I notice you are able to enter your garage door height with clearance. I want to do a 6 inch lift on 38 or 40 inch tires, but I’m concerned about my Jeep being too high for my garage doors.
Just wanted to share a thought with you as you also seem concerned about temps I ordered a mishimoto electric fan controller with the ability to control and adjust at what temp the fan kicks on I’m going to try setting at at 195 and pairing it with a mishimoto 180 thermostat this paired with a complete coolant system flush new coolant hood and inner fender vents and hood vent I think I can keep it sub 210F at all times
Hey Cody! Thanks for the support! I didn’t know that mishimoto makes one of those! What year is your jeep? And do you have any check engine lights? My only though about this is that the Jeep’s computer will realize the fan is coming on differently than the computer would tell it to and might cause check engine lights.
@@WarPaintOffroad 2015 I do not I haven’t installed yet it is on it way purchased last night i have high expectations for the set up I’d be suprised if I wasn’t able to achieve the my desired temp range
@@codysawyer6314 well DEFINITELY keep me posted. That’s a cool idea. I hope it works. If it does I’ll be ordering one and doing a video on it for sure. Let me know! I feel like this is only for an aftermarket electric fan. Like a pusher mounted to the front of the radiator. I don’t think this can work the factory fan. But like I said, fill me in when you try it out.
@@codysawyer6314 hey, Cody. Do you have any updates on how the Mishimoto experiment went? After having a head gasket go, and the extremely high repair costs, I am definitely interested. lol I understand these engines are made to run hotter, but i will never be comfortable with temps over 230. lmao
@@JerseyPR84 yea. It can be depending on the conditions when it crept up. Going up that high when climbing steep hills on a hot day when towing or with larger tires…that’s okay…as long as it comes right down.
Hey there! So I am just using a Dorman thermostat for the Jeep jk 3.6. You can get it at any local parts store or the internet. But I would normally use the Mopar one. However I couldn’t get it in time…typically the Mopar one is a little more expensive but it lasts longer in my experience.
No one these computers. They are programmed with a resistor. So the higher the temp gets the faster the fan spins. I don’t know of a way to do that and hide it from the computer. It’s also not necessary if you have a clean radiator fan shroud. They work well.
Would wrapping the cats with heat wrap help, I still say that's my they Crack heads or head gasket, I have a 2013 jku cracked head at 150k, my girl gas a 2018 grand cherokee gmhead gasket cracked at 110 k
It might. I could see wrapping the CATS keeping them a little hotter and making them burn off a little more of the garbage that plugs them up. But I don’t think it’s your head issue. I could be wrong. But you may just be having bad luck in that department. So many variables. Tough to say.
@WarPaintOffroad I understand that , the grand cherokee never ran hit, only leaks in the tiny cylinder when you shut off, it #6 under the intake manifold the back of the engine bay by the fire wall, not much room for the heat to go, the 13 jku was middle driver side were the exhaust port is, hence all the heat coming out the middle, just my thought, tour video was good
You have a different issue. Did you rinse it out like in this video? If so…and you are sure the fan is working…you might have casting sand to b the block somewhere..or maybe someone put the wrong coolant in and it’s starting to gel. Lots of things can cause it.
my gladiators tempature will keep climbing the faster i go, i cant drive faster than 65 mph or im at 230 f and climbing the faster I go, any guesses ??? probably need a new radiator?
Well…I’m going to disagree with that. Far from trash. They make good power and fuel economy. There are MILLIONS of them on the road and they aren’t stopping them. There are articles of them going over 500k miles with nothing but basic maintenance. I have a couple vehicles with this motor…and while I’m not claiming it’s the best motor in the world…it’s far from trash in my experience.
