LEXUS GX460 HAYDEN TRANSMISSION COOLER INSTALLATION 

Thanks William for the excellent input. 😀

Considering the $3.75 RU-vid paid me for the total number of views I received for this video, it was well worth it.

@@GXBOB Big Money!

Yo Gipstetz, always looking forward to hearing from you. 😀

I’ve reached out to KAON but unfortunately they cannot confirm the fit will work. Can you link the kit you used?

What year GX do you have?

Thanks for sharing Rodel. As with many other comments, i learn other facts that i wasn't aware of since i don't own a luxury or premium model. Good to also be aware of potential issues rising out of older trucks like u just mentioned. Who knows, when i get a GX470, i may attempt to take that route.

Is it worth putting a transmission cooler? I have a FJ which I use mostly for sand driving .

@@kanevivalakane3699 Any load you put on your tranny shortens its life if you don’t keep it performing under ideal temperatures. This includes driving outside the normal realm of flat street daily driving. If you tow additional weight or offroad (includes sand duning) I’d have an aux cooler installed.

@@GXBOB hello bob why don’t just get aftermarket oem is a lot easy to install any reason?

@@skeletronxxprime6277 oem is too small

I know there is an oem tranny cooler set for the 2021 from the dealer but unless it was sold with an offroad package, i don’t believe it comes with a tranny cooler from the manufacturer.

@@GXBOB like.. I mean the OEM liquid transmission cooler... I thought all GX460 came factory with them?

@@LexusGX460-OFF-ROAD Isn't that the internal system within the radiator??? The transcooler runs inside sharing the same cooling capacity as the radiator coolant. Thats why a people bypass the radiator due to the two mixing in the event the radiator cracks on older vehicles.

First of all, California invented bbq. Secondly, I would not tie the 2 horns together. When I honk the vibrations create a really weird sound. I would use thicker foam pieces between the brackets and structure. I would also do a complete radiator flush since I already introduced air into the system. Other than that, I’m quite happy with the install and the trans cooler.

do you have a link to that cooler you recommend?

i would reuse all the OEM clamps if possible. The ones Hayden provided works but OEM is easier and faster.

Awesome inputs. Thanks!

thanks for the input!

2017

I have a base model. It doesn't come with a fan. It came with absolutely nothing. It is so minimal in options that even the dealer was surprised i wanted it. I chose the base because it gave me more opportunities to work with and add custom accessories to.

Thank you??? Sorry there was no humor in this one because i had so much to cover and plus i'm running out of material for the vietnamese guy, Phuc Dat Bich or my girlfriend, Tyesha.

thanks for the input G5 !

Go to my profile and my email address is there. I had a garage fire recently and my stock burned to the ground. I am currently getting my fab guy to make more.

@@andrewvhoang any time Andrew! 🍷

I can’t answer for Tundras but most all trucks have the same general radiator setup with top and bottom hose . Only difference is the bracket install locations.

@@GXBOB the reason I asked brother was, because every cooler install for 19-21 Tundra on YT is adding a thermostat and bunch more work. In comparison what needs to be done with a GX460. Unless the GX already has a thermostat for the trans fluid already built in?

To be honest, it was intimidating at first but had no idea it was so easy to do.

Hey, you're not the first to inquire about them. I ran out and when a new batch was made, part of my garage burned down taking the lot of brackets with it. I am trying to find time to fab new ones.

@@GXBOB yeah as soon as i commented i saw the others. Sorry to hear about your shop! Thanks for the content and let me know if you get some more!

i can't use my GX as an example, but i had a toyota sienna tranny solenoid go out and all we had to do was drop the pan and replace the solenoids. They were fairly easy and straightforward installation. I probably won't do a video on that unless my solenoids fail themself but the answer is, NO, solenoids do not get rebuilt, they get replaced.

@@user-sf1zz5ew8v word of advice. Don’t bolt the 2 horns together. Install them in separate locations. They make a weird noise when you honk the horn.

Same process but different brackets than the ones I used.

Invest in one of these to help you out. a.co/d/3Aery4A Just manually continue to burp your system and your system will eventually air out itself.

you were an inspiration for my new video.

If you scroll down in the comments I talk about the bypass.

Thanks, always looking to see if others took the same route. 🍷

Pretty similar but your directions were sooo thorough, detailed and thought out. I was doing a trans fluid exchange, so it just made sense to add this. Just completed a couple of months ago. I sure would’ve loved those long needle nose and hose pliers. I fought with those hoses for way too long!

@@clas2002 damn, i can’t imagine doing this job without both those pliers!

you know there are plenty of sites you can find people parting out their GX or junkyards have networks that can locate the part for you.

I sold out. I’ll have some more made next week.

Yes it was! Thanks for tuning in Vader, i plan to visit Oahu next summer 2024 and rent a jeep. lol.

The stainless brackets were specifically custom made for the transmission cooler. I have a few more sets if you want to purchase the pair for $25 shipped. PM me.

Nice! Thanks for trusting me.

Sorry Johnson, that wasn't me. Most likely ACRAD from CL. We get mixed up a lot because we're both really good-looking men. Thats the rumor on the street.

@@GXBOB I thought you two were a couple? 😘

So I’m guessing my cooler for me going to the mall and back is over kill.

@@GXBOB hah, those parking lot in the malls does get pretty steep too lol

Hey nytron, i thought about doing that already. Just putting it on my list of stuff to tackle. thanks.

The general rule of thumb is to choose a cooler that is rated for at least three times the weight of the trailer you are towing. My travel trailer being a little under 2000lbs makes the Hayden 678 almost within the proper size range for the stuff i tow and I also considered the amount of towing i do. I think the Lexus oem one is a joke and is really meant for daily city driving without serious consideration to towing boats/trailers uphill to Big Bear in the middle of summer. I am still running my Hayden 678 and according to my tranny cooler temps, i can seriously say i sleep better at night.

@@GXBOB I didn't mean the trans-cooler built into the radiator. There are some GX460's and I think all GX470's have an external cooler. Driver's side near the horns. Also you did isolate the S/S bracket from the aluminum? That's a big corrosion problem waiting to happen. (stainless to Al) Thx

I’m glad they were helpful!

well.......i just like sleeping better at night, i guess.

@@GXBOB I sleep just fine.

If price wasn’t a factor, why wouldn’t you want the newer and more modern truck?

@@GXBOB thank you Bob! Will go for 460 then.

I sell them for $25 for the pair. Pm me.

my driveway is on an incline.

@@GXBOB ah ok cool cool 👍 Just barely a little came out enough to just cover my fingers a little. That had to be the trickiest for me lol. Appreciate the great video and your awesome personality. Thank you

that is awesome casey. i appreciate you using my tutorial do work on your own truck.

You’re welcome!

Cool, thanks!

The brackets are custom made. I have one more set. $25 shipped. Just private message me.

@@GXBOBdo you have an email? Sorry can’t figure out how to dm 🤷🏻‍♂️

Nah, just a weekend rental. Sometimes the poor scrapes enough money throughout the year just to rent one of these babies to see how it feels. I’m currently saving right now for next years weekend rental. 🤣

lol

20-40 degrees cooler. I pull a boat and a 3400 lb travel trailer uphill so any amount of temp drop is beneficial.

@rayvarnson8976 You should have seen the unedited version where I moved the fuel tank back 3 feet in order for the truck to not flip over once I installed the trans cooler.

I was selling the set of 2 for people that messaged me in the side for $25. I had a machine shop fab the brackets. Recently a corner of my garage burned down from a self ignited battery charger. My entire lot of brackets melted. I’m going to see if I can have them fabbed again.

@@GXBOB Oh shit! Very sorry to hear that and now I am paranoid as I have two vehicles in my garage with battery maintainers hooked up. Thanks for at least providing the dimensions...I may see what local shop around San Diego could do for me. Although...it seems like you could make something similar by cutting thicker sheet metal with tin snips and bending the corners in a vice. Stainless steel is obviously way superior.

I’m interested in a set of brackets

I'm also interested in a set of brackets. Might take awhile for Bob to get enough demand to consider having the machine shop do a run of brackets though...

Nah i'm not clever. I only used this video as a front to show off my babe magnet...The Porsche 911cabriolet. Oh yeah baby. Not exactly sure why i'm still single though. Maybe its because of my douche bag personality.

@@GXBOB Just the same, I'm benefiting from your experience as I just got a 460 and looking ahead to add-ons.

Are you talking about the sorry excuse of a cooler that's built into the radiator? Or are you referring to the external OEM tranny coolers only offered in the US market as an option starting in 2020 for Luxury trims w/Offroad package? Either way, an aftermarket transmission cooler to supplement the "extra" plumbing embedded in your radiator is the better choice if you are doing off-roading or towing, especially in hot weather.

​@@GXBOB I saw a comment on reddit that I misinterpreted to think all of the luxury gx's facelift onward in the US had the OEM coolers. Knowing now that my 2016 has the POS one built into the radiator I am 100% doing this mod again for my GX, butim going to totally bypass the radiator like I did with my 4runner.

@@hurpaderpp someone asked me about the bypass option and I replied with a lengthy response. You can go thru the transmission cooler comment section and read my opinion.

​@@GXBOB excellent video, my only question is I live in the very cold northeast. I know Hayden markets a model that is supposed to have special interior that restricts the flow in very cold weather. Do you have any opinion on this topic. Thanks for this great information.

i just ordered a scanner that was capable of reading tranny temps. Check back with me soon.

@@GXBOB sure .thanks Sir

@@kanevivalakane3699 So i'm doing a lot of eye brow raising because my tranny is running cooler towards the low end of the spectrum between 185-190 while towing on 4th gear. But then again, i never looked at the temps prior to the tranny cooler install so i have nothing to compare it to.

Damn blang, i appreciate the extra knowledge sharing.

@@GXBOB Overall it would be interesting to see if the average engine temps increase while the ATF temps decrease. If the engine temps are pretty much the same before and after the install then we are solid gold.

Hey GX Dan, i see we share the same first name. GX Bob.

Yo yo yo. Great question. The prospect of that happening is like every 10 to 15 years dude. Go buy yourself a new radiator and install it. The key is to consistently maintain your vehicle and being proactive. There’s alot of stuff i do before things break down. I’m not bypassing anything because what you’re doing is trading one evil for another. I’d rather have optimal tranny temps as opposed to running my tranny before it even has a chance to warm up. Doing that daily will lead to early tranny failure. An external cooler bypass only prolongs this process. An external cooler is only good to keep the tranny from over working while putting a load on your vehicle. You need your radiator daily. You need a cooler only sometimes, if that makes sense. Also keep in mind that liquid to liquid cooling is more optimal than air to liquid. In conclusion, if you want to sleep better at night, install a new radiator every 7 years or so. I call it the 7 year itch.

@@GXBOB thank you for the feedback! You are truly doing the GX community a service man! I learned so much from your channel and love your sense of unapologetic humor! Keep them wine pouring Bob!

Yes i have sold a few sets already. $25 shipped anywhere in the states. Just pm me

@@GXBOB hey gxbob I would like a set as well

I hate to say this but systems such as 12volt are plug and play which limits many other options that are programmable. An important feature needed to keep your engine running when u disarm your vehicle requires a double pulse to your vehicle's disarm input. I've heard so many issues relating to this. I reached out to 12volt but was unable to get a sample unit in order to diagnose for their customers.

What issue are having? I installed a remote starter and it has been working flawlessly for a little less than a year. I use it everyday in the winter months in breezy New England and some times in the summer.

Hi Bob, great video. This type of modification is preferably for users who must tow heavy weight and do offroad? And Is this transmission cooler something good to increase the durability of our transmission? Thanks Bob.

The protection was required throughout the length of both hoses. The loom worked well. Edge protector is found to be unique to only the radiator wall cut-out. I started padding the cut-out before i realized there were so many different areas the hose could chafe besides just the cut-out.

@@GXBOB thank you for giving me confidence. I will tackle this soon.

@@pennmikael easy peezy lemon squeezy.

@@GXBOB I finally completed this install this weekend. I made brackets using 1/8" aluminum- what a PITA to make without the right tools. I lost all the fluid while connecting the bottom line and ended up doing a trans fluid level check, which was good since it allowed me to check fluid condition as well.

George i don’t recommend it. I prefer to switch out my radiator before the average fail life of 100k. Preferably with an all aluminum or new Denso. Doing a bypass actually harms your tranny more than it does good by switching from liquid/liquid cooling to air/liquid cooling which is less optimal. Plus promotes early tranny failure by not allowing your tranny to warm up efficiently at every start up.

Good to hear. If your transmission blows up let me know so i can delete the video.

Mike, 1) I had to go back to install the loom after putting the bumper back because i didn't want to lose momentum. I would have to pack everything up (filming equipment, tables, stands, parts, etc...). If i took my other car i had nobody to stay and watch my stuff not get stolen. 2) The SS bracket thickness was roughly 1/32". I had a metal fabricator make the bracket for me as a favor, but that is overkill. You can just buy a sheet of metal from your local hardware store and dremel one out yourself w/ a cutting wheel. Use a pair of pliers and table vice to bend them into shape. I would have to ask my fabricator if he is interested in doing some side business but i'll get back to you.

Ok thanks Bob,

@@mikemitchell9138 My fabricator can make a pair of custom brackets identical to mine in stainless steel w/o holes for $25 free shipping. Reason no holes are due to the variation from vehicle to vehicle.

@@GXBOB That’s great and thanks! What’s the best to contact/pay him?

@@mikemitchell9138 I’ll reach out to you when it’s done. He said next week. And I’ll sit you a number for venmo or zelle

Thank you Enoch, i appreciate this comment. It helps me to understand what i need to do better. Thanks for tuning in.

I bet you my camper is bigger than your camper. Thats why i get all the hot babes.
