My stock trans line on my daily 00 finally rusted through (thanks PA) so its time to order this. Thank you for being in depth with this!
No worries! Glad to help! 😎👍
A well done and thought out video. Great job.
Thank you so much for watching
Flawless! Thanks for such a great videO!
Thank you I appreciate it!
Very nice man…I like that setup!
I appreciate it man 😊 thanks for watching and we’ve been through 2 trips with it so far and haven’t had an issue so I’m really happy with it.
Love the sway bar links btw lol😂 that's great
Thanks! 😂 I got an upgraded sway bar now so I don’t need to deal with those anymore
Nice set up,will make a big difference I am sure of that.
Thanks for watching man! I think it will make a large difference with this AZ heat.
I got the Derale Atomic Cool as part of my XJ overheating problem attack plan (along with new rad, fan and shrouds). I also installed a trans temperature gauge and noticed the transmission heats up more than the engine under some conditions, so I’m very glad I got the trans cooler. It makes sense since youre spinning the wheels etc. During the install I discovered the stock trans cooler was clogged, along with lots of bent and kinked trans lines. Night and day for me, all my heating issues were solved.
Overheating attack plan I love it! I think an external transmission cooler is a must on the XJ’s especially one with a fan. A clogged and destroyed stock trans cooler can definitely cause some overheating issues with the transmission. The better fluid and airflow the better 😎 thanks for watching
@@2AOverland Totally!!! Its a big must, total game changer and very often overlooked, hardly anyone does this. Out of dozens of comments giving advice on my heating problem, only 2 mentioned the trans cooler. That and watching your video multiple times I went ahead and got the Derale, night and day man. Thanks for posting, its the only video on TH-cam for an XJ remote/fan trans cooler installation.
@@2AOverland Finally got this model for my buddies f100. Great video man, every time I watch it I learn pick up something new.
No problem thank you for that man 😊👍 I’m gonna do the same coolers for my square body a trans and engine oil cooler
Nice! I definitely wanted to do this before I ended up doing a manual swap on my XJ.
I’d say a bit of advice would be to look into a thermostatic control for it. That way you never have to worry about turning the fan on or off, cause while it may not be near as bad, over cooling isn’t good for an auto.
Before I manual swapped, I bought a thermostatic control from American volt. The AW4 operating range is 125°-175°, and I got a thermostatic switch that would turn on at 150° and turn off at 135°. That way it’s always keeping it in range. The kit comes with the hose barbs too so it’s incredibly easy to do. The solenoid control would just be *before* the cooler and you’d have a solenoid signal wired up to it. Such as battery positive to the switch, then the switch to the solenoid. And then maybe your ground runs through the solenoid. And it’ll turn on the fan on and off as you see fit, and you could even have a manual override too. Just an idea if you’re interested in having an “out of sight, out of mind” approach. I like to drive hard in the sand, so a cooler was a big priority while I still had the auto
Great video! I loved watching. Glad to see there’s videos that aren’t just using the average cooler, and now showing fan cooled ones too
That’s brilliant!!! Thanks for the info man! I want it to be as painless as possible so I already have that kit in my shopping cart 😂 I’ll figure it out how to wire it up so it’s automatic and I can use the switch.
Thank you so much for watching! I’m trying to be more outside the box and do budget minded but high quality upgrades to the jeep that I know people would want to watch
@@2AOverland you got it! I think that would make it so you can just forget about it and not have to worry about it.
My hunch is that you’ll need to split the ground lead from both fans into two separate leads. You keep the lead you already have connected to the auxbeam and that allows manual control. On the other lead you get a solenoid rated for the current it’ll draw (I believe you said 10A?). Run your secondary lead from the grounds into the solenoid, then from the solenoid to battery negative or just grounded to the body somewhere. Then you just wire from battery positive (or ideally ignition 12v that way it doesn’t run down the batteries on a warm shut down, but I can’t imagine a problem), to the thermostatic switch, then from the thermostatic switch to the relay. I believe there’s a signal ground needed too, so I think in that case you’d just splice your signal ground into any of your ground wires for the fan. But don’t quote me on that part.
For the thermostatic switch, you’ll want to make sure you get one that has the barbs sized for the inner diameter of the cooler lines. Should be pretty easy to make a few cuts and splice the switch in. Also, as I’m sure you could imagine, make sure you put the thermostatic switch in *before* the cooler (even the factory “cooler” too if you have it still). You want to see the temps right out of the transmission, not the temps before. It should be easy to figure out which is which. I get everything warmed up, then put the fan on at full tilt. And use a temp gauge to see the surface temps of the lines from the cooler. Whichever one is consistently hotter will be the line from the transmission.
Also you could even set up your ground wires so it’s just one ground wire from the cooler to about 12” before the auxbeam and then do the split there. The current will be no different if you have it run through the whole ground line instead.
For sure! I really enjoyed watching it! I know I’ve been watching your IRO 3 link video over and over lately. It’s really well done and it’s making me be sure I’m prepped for when I install mine.
Best of luck!
Man that’s so much info for me to use to install the kit 😊 thank you so much for that! If I make a video on installing this kit is it okay with you to add a screenshot of this comment to explain how to hook it up? And thanks for watching the 3 link vid! 😎 I’ve had zero issues with that kit and you’ll love it!!
@@2AOverland sure! It is all theory since I haven’t been able to do it myself but I have every reason to believe it should work great!
Yeah! It was a fantastic video. Easy to follow. Thank you! I’ll be installing it pretty soon, hopefully
Nice set up . Question - could there be a air pocket problem mounting with the trans cooler connections both on the bottom ?
I guess there could be in theory 🤔 I’ve been trying to research how much psi the transmission pump pushes but I haven’t had any luck. We did test the cooler this past weekend on a trip and haven’t had a single issue!
@@2AOverland The air will not purge out of a plate cooler completely unless the fittings are UP or sideways, if sideways the from the trans line needs to be the bottom fitting. Look at any piece of heavy equipment, caterpillar for instance, the cooler is almost always mounted fittings sideways so the cooler can purge and drain .. NICE install mounting
Looks nice. Could you weld a piece of angle iron on the backside of that piece its bolted to in order to protect the fittings?
Thanks man it does make a big difference from what I’ve tested. That’s a good idea though 😳 I don’t know if it will protect much against rocks while wheeling but the occasional rock from the road or bushes on the trail it would work perfect! I’m gonna add a piece of iron thanks man.
@@2AOverland No problem, glad you like the idea hope it does help. Just got a bone stock XJ last week trying to plan out all my different upgrade options
That’s awesome man! What year xj did you get? And the xj community on TH-cam has lots of great info from what I’ve seen. If you have any questions please feel free to ask 😎
@@2AOverland Got a 1999. Very clean, almost rust free which for my area is impressive. Been watching lots of different videos. Appreciate it, love your videos and will be doing several of the upgrades you have done videos on.
A year later… looking to add a similar cooler to my JK. How has this model done with your trans temps?
I’m still not running a transmission temp gauge after the cooler but I haven’t had an issue at all so far with it.
how bad were the air bubbles . noticed you installed wrong up . left or right but never down.
Thank you for watching! You have a point but I haven’t had an issue since the install tbh. I think the transmission pushes enough fluid PSI to push it through the cooler no problem
Do you have a trans temp guage to monitor your temperature?
I don’t yet. That was an upgrade I was gonna do sometime before summer starts
This is exactly what I need! It looks expensive though :/
The whole setup was a little pricy compared to other setups but these fans are weather and waterproof and the dimensions almost fit perfect in the spot I mounted it so that’s what sold me on it 😬. I figured the cost of the cooler is cheaper than a transmission rebuild if it gets too hot 😩
@@2AOverland good point. I’m also wondering if it may help the engine run a little cooler by removing the stock trans cooler from in front of the radiator 🤔
That’s exactly what I was thinking. Less crap for the air to flow through lol. I think it could make the ac run cooler also
@@2AOverland one things for sure, it won’t make it worse, lol. I look forward to seeing an update once you’ve been running it for a while.
That’s a good idea! 🤔 I think I’ll do an after summer update on the cooler
Why didn’t you add more weld? 4 small tacks when you could have put two 1 inch beads on the top edge.
This is one of those mods that no one notices, but are critically important,.
I don’t think you’re supposed to put Teflon tape on AN fittings..
Job well done!!!
Honestly there’s no reason why I didn’t add more 😅 you’re right I should of had a couple small beads instead of tacks but I think those tacks will hold and if they don’t I’m welding that whole damn thing in 😂.
That’s exactly what I was thinking! An overheating trans will kill it so fast so I figured a beefy trans cooler will be more than enough and it’s an easy upgrade for anybody that wants to recreate it!
I don’t think I was supposed to either but I made sure it was way away from the threads so there’s no chance of leaking 😬 as long as it doesn’t leak I’m happy lol
@@2AOverland I had to build my own trans cooler since they quit making the behind the grill version for the TJ/LJ.
Unfortunately I had to do it 3 times. The first version was too high. I didn’t notice but the hood latch hit the top of the cooler and made it leak after a couple weeks. I bought another cooler and modified the mount but over tightened one of the fittings and it split so it leaked all over the place. The third version has been great. I’m going from the transmission to the radiator, out of the radiator into the cooler, and out of the cooler, back to the transmission. In the summer it’s not ideal, but Texas winters can get very cold, so I needed to add heat to the transmission.
On a side note: the thermal expansion rate of the transmission fluid is crazy high. 20* different radically changes the fluid level
Awh man that’s some bad luck! I thought about doing the same trans/rad/cooler method but I bought my cold case radiator from a local guy he lost the trans fittings so I figured I’ll just run an external trans cooler and save me time lol
You dont tape them because it can keep the fitting from seating properly and causing a leak that may or may not be stopped by the taped threads.
So for your transmission line routes, do you still have the lines going to the radiator or is going straight from the trans to the new cooler and back?
Sorry for the late reply! No lines going to radiator at all 😊 straight to trans from cooler. You can run into the radiator too but I wanted those systems separate so heat from the trans fluid transfers into the coolant from the radiator
@@2AOverland what about your power steering lines? The way mine is setup is the trans outlet goes to the cooler infront of the radiator, the it goes from that cooler to the top of the radiator internal cooler, then comes out the bottom of the rad cooler and goes to the power steering reservoir
@@2AOverland nvm I was looking at it wrong 🤦♂️ the ps doesn't tie into the trans lines lol I thought that was weird as hell bc it is 🤣
I'll be doing the trans cooler upgrade and temp sensor soon!
Sorry for not replying to the last message! No worries though! I’m glad you got it figured out and you’re gonna love that trans cooler upgrade man 😎
@@2AOverland getting mine installed today with a temp gauge kit 🤙 I got the inline temp switch to control the fans as well so it will be maintenance free
Also, do you ever travel up to Utah? I'm taking a trip in September and it would be rad to wheel with you if yall wanted
Flip it. Put the fittings on top?
I forgot why I didn’t but it was some type of clearance issue
Is the fan designed to be either a push or full fan?
It could be either. Just flip the wires to have it go either direction
@2AOverland Yeah, I noticed you mentioned that but are the blades designed to do that? Looking at putting one of these in both my XJ and 5.9L ZJ to prevent excessive heat offroad. But location is going to be dependent on if it can actually push or pull and not just have the polarity changed around. Know what I mean?
@Krawler69 I gotcha, and that’s a question I don’t have an answer to 😬 when I did the coolers on the squarebody I did have to flip the fan blades for better airflow but I would do some testing before installing with this one since I used a different model on the squarebody.
@2AOverland Gotch! Well, I appreciate it either way!. Awesome video, sold me on the modification when I was browsing what to do with mine. That 5.9L trans hates the heat. So have to figure something out with it. The AW4 isn't as bad but better safe than sorry with just putting a 4.7L in it.
Fuck how loud it is, I want to kno wut the before and after temperatures are
I don’t have that info but running this for a while now and the transmission is still alive so it works. Even during the AZ summer months
