    Finished install of thermostat and hoses , I would say that it was the easiest part , the hoses on the thermostat were easy going no problem getting it fit . The one that needed effort were the setrab hoses to the hardline.

    just gotta fill up the 1.5 qt , need a shallow 24 socket , the ones I have are deep and can’t fit it with the torque wrench in there .

    Snugging the hose on the hard lines has to be one of the hardest parts of the install IMO. What does help is coating the inside of the hose with ATF prior to slipping them on.

    Completed the installation after work , tested the truck for leaks, went for a 20 min ride and couldn’t get the pan above 150 and torque above 170 with the pin on .
    Checked for leak and everything looks good .
    Will take it for another spin tomorrow and double check again before I put back the skid plate .
    Overall I am happy it is done , glad I went with this kit , everything really looks factory and everything needed was provided .
    Really not hard to do installation, just take your time and make sure you have all needed tools . Took me 3 days to complete due to my time schedule ( worked For an Hour or so daily, plus truck is not my daily drive ) each time would complete a part of the installation .
    Thermostat install with hoses took 25 min .
    The worst part is the hardline and secure it with the bolts and also getting the setrab hoses into it , other then that straight forward , anyone can do it .

    We’re you able to connect the tstat hoses to the hardlines before fitting them in place?

    That is exactly what I did .
    Before i installed the thermostat, I tried the hoses on it and they were very easy to slide in , so decided not to hook it before Tstat installation , figured would be easier to get the thermostat on first without having to deal with hoses working against me and glad I did .
    After I installed the Tstat (pretty straight forward) I torqued the bolts as indicated 15lb/ft and then started with the hoses first at the hardline and it was not bad at all, didn’t give me any issues getting it in . After that was done ,I hooked the hose to the Tstat. Of course start with the upper one first .

    Is having extended needle nose pliers a must? Although I don't have a pair in my arsenal and I don't mind an excuse to buy a new tool.

    I used a regular one , sure an extended nose would have done it easier , but managed to do it with just a regular one

    It sounds like it’s not a must, but new tools never hurt anyone :D harbor freight ones work great and don’t break the bank.

    It does sound like you can di the install in stages. I'm thinking of doing the stuff under the grill first.

    Yes you can , I assembled the cooler to brackets and installed the fittings on it and covered it so nothing can Get in to it.
    Second day was removing the grill and skid plate and pass the hardline and secure it . I also secured the cooler to the truck and connected the setrab hoses to hardline and cooler fittings . Make sure you tape the hardline so no dirt get into it while you are passing it through the engine .
    I would say this by far was the hardest part of installation

    third day installed the thermostat and hoses and add the oil and level check , that was the easiest part. just take your time and you should be fine

    keep in mind that I don’t need the truck for my daily driving and I was able to work on it for an hour or so daily

    Took the truck today for highway test driving anywhere between 75 and 85 (normally don’t do that ) to get the temps high to see what I get and was not able to get the pan more then 194 . TC would go to 218 or so and drops back to pan temps which is expected( tried to keep it unlocked to get those temps up there)
    Checked for leak again to make sure all is good . The cooler was hot to the touch which means the thermostat did its thing and opened around 194 .
    Got help tonight putting back skid plate

    Is there anyone with in an hour or two of Wellsboro Pa. that could assist me with this install? I will gladly pay you for your time. Just looking at my garage situation and it's gonna be really tight!! Plus and extra set of hands would be great?

    Not that difficult actually. I did the install today and it was super easy. I have been wrenching on vehicles for 35+ years but it’s pretty straight forward. There is a YouTube video, I will link it. Pretty good watch. I will say that the pipes were easy to snake though and I found it easier to install the rubber hoses from the T-stat body to the pipes after the T-stat and pipes are in. Other than that check fluid correctly.

    Has anyone done the install without removing the TRD skid? that thing is a pain for 1 person while the truck is on the ground. IMO.

    I'd imagine its probably a similar situation with the RCI skid and I didn't need to remove mine, it wouldn't have made any difference if I did because it's not blocking where I needed to be.

    Take note that the kit used in the video is different from the one you purchase so everything isn't "exactly" the same, that threw me off at first. I printed off the paper instructions from the website in color and they were great to follow while using the video to get more angles of where I needed to work. Just set aside a whole day and take your time. You can practically work in any order that sounds easiest to you. Although I will admit, as nervous as I was, if there was a GOOD shop within 1-2 hours drive I trusted, I probably would have paid lol. But now that its done I'm glad I saved the money.

    Wondering the same thing. Just ordered the Setrab kit. Don’t want to remove the TRD skid plate if I don’t have to.

    For installation of the setrabusa 15 row the instructions say the following.
    D4DCFB2D-75E5-497D-A2D3-2F24ACA0EE15.jpg
    with the orientation of the thermostat inlet/outlet it makes flow through the cooler go in at bottom of cooler, out at the top going back to the thermostat.

    Is the correct?? Seems like flow through cooler should be top to bottom?

    I though the same when installing mine. I believe bottom to top helps ensure there is no air trapped in the system.

    I did my own system and messed up on the line, kinda. It’s been long argued that air gets trapped. Some say trans oil pressure will always push out any air some say it doesn’t. I noticed to late and had all my lines hooked up. I used a temp gun and the temp through out the whole cooler was as it should be. Hot on the inlet and cooler as it reached the outlet. I am OCD and will eventually buy more hose and reroute it but top or bottom I think is a moot point. Also the system doesn’t stay pressurized when you shut off the truck so there will always be air pockets till pressure builds back up.

    MHX documentation states the inlet is on the bottom.

    EDIT: when the heat exchanger is oriented horizontally.

    Has anyone here spray painted the MHX cooler black? I have some Eastwood radiator paint en route but am curious about prep before application.

    Install tip:

    When fitting the 3/8” lines to the hard lines up front, use a q-tip to coat the inside of the rubber hose with ATF and get the rubber line started onto the hard line. Once started use a heat gun to heat the line which makes it more flexible. Once the line is warm, use a twisting motion to push the rubber line onto the hard lines without so much fuss.

    7" BDS Lift, Transmission cooler install
    I installed the kit a few days ago with one of my friends. I called around to two dealerships as well as an independent shop and no one wanted to install it, glad that happened b/c it really is pretty straightforward and I saved myself some money.

    So for the install, having a second set of hands makes the install go much easier. The guy that made the you tube video of the install did a phenomenal job and its well worth the watch.

    A couple things we did when installing it was to put the "coolant in" and "coolant out" hoses on the thermostat before installing it. The hard lines were pretty easy to snake into place with two people, and once you get it in place all the bends on the lines make sense. To get the rubber hose onto the hard lines we put a little ATF in the rubber hose and I pushed them with a slight twisting motion onto the hard lines from the top of the engine while my friend held the hard line in place from under the truck. I got the MHX radiator with the plumbing on the side, so we hooked up the lower port first, held the radiator in a vertical orientation, filled the radiator with ATF, then secured the line to the upper port. Was quicker to get the ATF fluid in this way vs pumping it in from the quart bottle under the truck.We then attached the radiator/bracket assembly to the truck. Again, much easier to do with a two person install.

    I chose to keep the thermostat pinned and have been monitoring the pan temperature for the last few days. I don't think its gone over 170 even when really pushing the truck. I drive on the beach, have a lift kit with 35's, and have had the transmission high temp light come on about 7 or 8 times over the last two years. Of course the service advisor blamed the lift and larger tires, but I had a 2011 Tundra with the same lift and tires and never had the transmission high temp light come on in the 8 years I drove it on the beach.

    I'm getting the transmission serviced in the morning tomorrow, so I am interested to see if they say anything to me about the install. I hope the tips help, and thanks Nick for putting together a great kit at a great price!

    Let us know if the dealer says anything about the cooler setup. Would be interested to know if they care about it

    7" BDS Lift, Transmission cooler install
    The service advisor I had today actually acknowledged that Toyota did omit the transmission fluid cooler in the new Tundras. I was actually shocked they did. They also agreed that it was a good mod to install, and didn't understand why Toyota got rid of it in the first place. Now only if we could get Toyota to reimburse us for the cost of the kit!

    As far as accessing some of the more difficult to reach fasteners: any tips or special tools recommended?

    Sockets with u-joints, ratcheting combo wrenches, long nose pliers for the clamps. The thermostat bolts don't require too much torque, so just get them snug with an extra 1/4 turn.

    I used a slim long reach combo wrench to fasten the hardline mounting point on the engine block near the transmission. U joint with socket, ratcheting socket wrench and extension for the front mounting point.

    The thermostat required a socket wrench to break the bolts loose, then I used a ratcheting combo wrench to fasten the thermostat after getting the bolts hand tight.
