Thanks Kelly , I’m part of a Rally team racing across Europe and Africa. This install was crucial to my piece of mind while traveling. I could use some extra cooling power and good luck along the journey. Thanks again
Nice work on this video and tutorial. I think this is the way to do it. For some data points, I installed a similar auxiliary cooler size on my 2000 in 2012 with around 120k miles and watched my transmission fluid temps reach 250° when climbing passes in the mountains often. I paybassed the OEM cooler like everyone talks about for fears of the dreaded failure or “design flaw” we all know. At around 230k miles and 10 years later, the trans ended up failing because of those consistent high temps and I had a lower mileage used one installed. I’m still seeing high temps (~230+°) when in 4 wheel drive climbing passes in the winter, so I think the auxiliary cooler alone is not sufficient for my rig. Maybe sufficient for others, but that’s not what I’m seeing. So I am going to reconnect the lines to the factory cooler just like you did, just 10 years and one transmission later! Thanks!
What most people don't understand like one of the replies is, the trans actually needs hot Temps to operate and shift correctly. So seasonality and location have a fair amount of input here. A thermostat control control valve would be ideal or if you live in a really hot or really cold location. Not cooler in the winter full cooler in the summer, especially if towing.
Bypass is good if you have a brand new radiator and a sufficient cooler. But the series method is what Toyota does to all the rigs that come factory with trans cooler. So this TH-cam is spot on installation. Also, you actually void most manufacturer warranty if you install the bypass method. I did mine with the 699 model (built in thermostatically controlled to allow cool fluid to bypass through the first couple rows of the cooler). This model is good if you live in colder climate. Instead of using the junk zip ties, I chose to bracket mount mine with the Hayden bracket kit. So the transmission cooler never touch the condenser or anything else. Using the zip tie method is ok if you plan to not do hard off-road because with time, the zip ties are bound to come loose. When it does, vibrations will cause leak if the condenser is rubbing against the cooler. The BEST method is to properly mount it with brackets. I took advantage of Timmy the tool man's method but did it slightly different without any drilling or having to bend the bracket. It fit like a glove. th-cam.com/video/34wnfq85_qk/w-d-xo.html
Thanks for the informative video Kelly! Did my first trans fluid flush on my 2001 SR5 4Runner with confidence thanks to your how to video. I added a Magnefine filter on mine and a cooler. Seemed to run great. Unfortunately I was trying to save my trans because I had a supercharger whine coming from it. No avail. Diag’d it as a bad torque converter.. just had it rebuilt and I’m reinstalling today in my driveway. Wish me luck! I look forward to more of your videos man. Next I think I’m adding a temp gauge to the trans..
Out of all the video for this mod. Your is da best! clearly easy to follow and thorough. I click on the link to purchase and said it doesn’t fit 02 4runner. Just want to make sure the correct part before ordering. Thanks so much!
Awesome video. I'm looking to do the same and it's nice to see you're keeping it tied into the radiator. I don't live where the cold would be an issue, but I also wouldn't want to lose that factory feature.
Great install video. I'll be tackling this project on Thursday, just replacing an existing leaky trans cooler with a new cooler and lines. One observation: my 97 4Runner came with a dealer-installed tow package that included a similar trans cooler. I don't know if the cooler is OEM Toyota but the first owner had it done at the originating dealer (also they zip-tied the trailer harness to the fuel line and that's nuts!). Anyway, the cooler was installed in the centre, and that small vertical crossmember (that supports the hood latch) had actually worn into the cooler and put a hole in it. Perhaps it is a little thicker than the Hayden. The clearance there is **very** tight. I notice you installed yours with part of the cooler behind that crossmember. I would advise avoiding that area all together.
hi KELLY , YOUR VIDEOS ARE AWESOME AND WELL EXPLAINED !!! im starting to overland my 97 SR5, i already have rear and front armor with a 13500 x-bull winch and so far 265-75-16, sometimes i drive my truck once a week and planning to go trailing next year, my question is which HAYDEN trans cooler do you think is the best or which one should i choose 678 or 699? should i install the cooler straight to the trans avoiding the radiator? cuz you never know the pink milkshake. thank you in advance.
Is the extra filter necessary? Also what if you want to bypass the stock cooler, how would you run it? Feed side to bottom of the external? Then new return line connected to the old return line?
Hey Master! Im from México i have a 4Runner 95, 4wd 3.0... i like your video, i try too instal the same system in this week... i text you, after too finish the work.
Do you have a link for the sheathing you use for the 11/32" hose? Would it be similar to PET Expandable Braided Sleeving in 1/2" size? Thanks! This was a super helpful video. Do you have any concerns over mounting directly to the condenser? I am on the fence about bending up some brackets to have it independently suspended. Just regular driving on my part so no real concerns about vibrations from offroading.
Thank you for this video. I did this same in-series method. Just curious what your new temp. readings are? For me, prior to the install my trans temp were averaging 178ish. After the install, the temps drop down to 89ish on avg. I'm a little worry because that's a drastic drop in trans temp. Keep in mind, this is just city driving with AC on (before and after). I haven't got the time to test very steep inclines to see what the temps will hit with the new cooler. But without, it was was hitting 220 - 240ish. Update: Never mind. Went back and check my notes and the after installed temp was actually 155ish so I think I'm good.🤣
Wouldnt it make the most sense to mount the intercooler as low as possible on the radiator with both ports facing the sky so its oriented horizontally? If the ATF cooler side is on the bottom of the radiator the more the cooler is there the more efficient the radiator will be
But the hot fluid usually is attached on the upper part of the new cooler, isn't? I'm seen so many different ways to ad a cooler in series... some say that once the fluid is colder should go down whit less resistance. I really don't now which is the best...
Thanks for the install video Kelly! As these 4runners are known to have the factory trans cooler fail inside the Radiator, could this cooler be used to bypass this issue instead of a full rad/ trans cooler replacement?
Thanks, yes i briefly mentioned it in the video. just runs the lines to it. The return side it the same as I did. Disconnect the pressure side from the oem cooler and install to bottom of external cooler.
@@Beacon_Offroad you do realize that the point of a trans cooler is to not use the radiator due to coolant and transmission fluid mixing in the radiator which is a problem these T4R have. You did it completely wrong. It fixes nothing
Isn't the whole point of doing this mod is to bypass the integrated trans cooler to avoid trend and coolant from mixing and destroying your transmission..I get that this will provide extra cooling, but it seems kind of pointless to me if you're not bypassing the integrated cooler.
Nice video but I’m confused. Isn’t the point of the external cooler to prevent failure of the internal cooler mixing fluids? I see you ran it through both coolers
Yes and no. There's multiple ways of looking at this depending on application and planned use. I'm not overly concerned about mixing as I stay on top of my stuff. You can actually over cool your trans fluid depending on outside temps and tome of year. The trans operates best at with warm fluid. This setup will cool hot fluid and warm it to correct on the way back into the trans. Running it a thermostat control would be the best way but it costs more and more difficult to setup. Hope that helps you understand a bit more. I could keep going but that should cover it.
@@Vosmalus when I do my timing belt I change the radiator. Probably the best way you're going to prevent milkshake from happening. By running a standalone transmission cooler and not running it through the radiator when it's cold out you won't properly warm up your transmission.
Yes, but as mentioned, it's a good practice to pop a new radiator in a 3rd Gen 4Runner as a maintenance item much like lower ball joints are on these. Those are the only 2 weak spots on these. Radiators are cheap (115 USD for an 'OEM ' Denso unit) and easy to install. This prevents the Pink Milkshake but retains the heating functions the Toyota engineers intended. New upper and lower hoses and a new OEM thermostat with the jiggle valve a 6 O'clock and you're good for another 250k miles. Edit - while you're at it, get a trans temp gauge or OBDII gauge or app (1999 and later trucks only) to monitor temps when wheeling or if you tow in mountains. The idiot light doesn't come on until about 300 degrees and you're risking real damage to your tranny at that point. Blah blah blah - sorry. Nice video!
@@jameswatt4694 So- I picked up a 99 SR5 with 169K miles PO took really good care of the truck all Toyota hoses and belts etc & looks like the original radiator as I can faintly make out Toyota on the radiator. I should be good with replacing the radiator with another Toyota radiator and no need for the external trans cooler? I plan on doing no heavy 4wheeling or towing. Tia
@@richardmiller2313 A new radiator is a good idea for sure. External trans cooler isn't a must unless you are wheeling in high heat under heavy load. It's never a bad idea to to hook up a simple data system to the OBDII port - either a Bluetooth unit that send all the data to an app or a full time unit like an Ultra Gauge or Scangauge II. I'm not even sure what thread I'm relpying to here, but if anyone reading this want answers to anything you could imagine having to do with 3rd gen 4runners (96-02) you want to check out this forum. I've learned so much about keeping these running forever and all the mods you can do from nearly free to sky's the limit: (it's an bit of an oldschool interface): www.toyota-4runner.org/3rd-gen-t4rs/ Cheers!
This is a balancing act. Depending on use, time of year and location. Factory cooler doesn't cool enough but it is meant to heat the trans fluid at a certain point as well. Depending where you live can be a factor. Here in the winter running a external cooler only would over cool the fluid.
I dont think it really matters and let's be honest if there was a major failure and large amounts of metal you shoukd extensively clean the cooler and or just replace it in general.
Hey Kelly. I'm wondering how all the added parts and passages affect the oil flow, and if that's something to be concerned about. There must be a pump pushing fluid out of the trans, creating enough pressure to push fluid back in (at least in stock configuration).
As a transmission expert, you should never bypass the factory cooler. When adding an auxiliary cooler, you use the lower return line from the radiator. Then that line will go into the auxiliary cooler then auto to the transmission input. The coolant in the lower part of the radiator is the coolest it wiil be before it goes back into the engine. As for my FJ cruiser the factory thermostat is 180°. Also use 5/8 transmission line, not the line that comes with the cooler. 5/8" has more flow/volume.
but these Gen 3 radiators fail and leak radiator coolant into the transmission. So what is the problem with Not running the trans fluid thru the radiator? is it bc the trans fluid then wont heat up to a proper temp? seems like that would only occur in very cold climates in the winter...or does it happen in moderate climates in the winter too?
It looks like it will only prevent the milkshake if you run the cooler bypassing the radiator. If you run it in series like this, it will still run through the radiator. So there is still a chance of the radiator failing and, in turn, the dreaded pink milkshake!
Why don’t you just use the external cooler? one main reason to have an external cooler is to prevent transmission fluid and coolant mix together when the built in cooler fails.
you do realize that the point of a trans cooler is to not use the radiator due to coolant and transmission fluid mixing in the radiator which is a problem these T4R have. You did it completely wrong. It fixes nothing. Plus the filter has to be before it flows into cooler. If anyone thinks it’s fine I’ll replace radiator every timing job, then that’s dumb due to it happening before timing is needed because it’s a flaw in factory design.
I understand exactly every point of what your saying but if you don't understand why it's set up like this then it's beyond you. Thanks for leaving a comment, have a great day 👍.

Well done man. I think "in series" is the all around best way to go. Your video made install a breeze.
This is an awesome video. To the point, edited, exactly what i needed.
Can the possibility of the milkshake mixture still occur with this set up?
Yes
My same exact thoughts. Why not just bypass the freaking transmission cooler in the radiator isn't that why you do that? 😢
