Tranny oil cooler completed

As the title says I just finished up my install on my truck. Was going to buy the kit from Genuine Cooling Systems but it continues to be sold out. Along with that, I sourced all the hoses, clamps, hardline and everything from my local Toyota rep for about 1/3rd the cost from Genuine Cooling Systems. Bought the same Setrab 15-Row Series 9 Oil Cooler and it looks great. Just wanted to share with you all.






*I've been asked to share part numbers of what I used*

I don't mind helping fellow Tundra owners out at all. Below is the list of what I used, it includes all the Toyota part numbers and quantity of each part on the left. The OEM oil cooler itself I bought from eBay. I bought the hardline, the 2 inlet/outlet hoses, basically the exact parts for pre 2019-2021 model years that came with a factory cooler installed so mine looks 99% factory all the way through. My oil cooler is the exact same one that Genuine Cooling Systems uses. This route cost me about $450 total.

If you really want to go with the cheapest option, you can just buy the OEM Toyota cooler assembly (32970-34030), about 12-15 feet of 3/8 heavy duty oil line, some spring clamps, and the oil cooler of your choice with barbs or AN fittings to mount by the radiator. This option excludes the Toyota OEM hardline, OEM 2 inlet/outlet hoses and you would essentially run the lines all the way up. You can then zip tie the lines underneath all the way or secure them however you want. That option would be under $350 easy.

Nicely done!

 

A must have for those of us with shark fins. The price we pay for being slightly stylish.

 

I just installed mine a couple weeks ago too. Used @Jmunk ’s bracket. My temperatures used to get up to 225 on my scangauge just on my commute to work. Hasn’t gone over 188 since I installed the cooler. I am anxious to get back up to the lake - we are going in a few weeks. Last time we went my temps were 240+ going through the mountains

 

Haven't heard about that bracket you speak of. I am going on my archery hunt this weekend so I am also doing the transmission drain/refill. Peace of mind knowing the temperatures won't get up there now.

 

he is a member on here who cut and powder coated some really nice brackets for the Hayden style coolers. Really secures the cooler and gives it a permanent solution to mounting

Ahhh I see... Curious to see what yours looks like if you got a pic?

 

I had a little different scenario; the Hayden cooler is larger and I have a sensor relocation bracket that was getting in the way. So I had to extend the mounting points with a mending plate to clear the sensor. Works great

 

How is the cooler attached to the truck? Did you make a bracket for it?

 

Yes I bought 2 brackets that bolt directly to the oil cooler I bought and they have bolt holes. One mounting point is where the passenger horn was, I just pivoted my horn downwards and used the same bolt. Then I have 2 mounting points on the bottom bracket/oil cooler. The bottom has a mounting point on the radiator support and then I mounted a little bracket from the center of the radiator support arm. It's solid.

 

Clean install. What did you do for the install brackets, any detailed pics on that please?

 

I didn't take any pics of the bottom bracket and how I mounted it up but I just used the bottom and center radiator support. The bottom radiator support has a threaded hole and I think it was an m8 1.25 bolt that I put on there to hold the bottom bracket. Then the center radiator support also has open bolt holes, I used a 1 inch 10mm bolt with a washer and nut to mount the bracket on that side. I would take pictures but I'd have to take the grill off and I'm lazy lol.

 

Im glad to hear that your temps are much better, hopefully it extends the life of the transmission.

 

Can’t thank you enough @jza80king! You saved me a lot of time and money.


Recently I just put on 285/70R17 tires and I am a little surprised how much more heat they generate in the transmission.

Generally in the past I have had no problems hovering around 203, empty. After the new tires, 217. Not a comfortable margin any more.

I was just going to buy the kit from Genuine Systems but I don’t want to wait.

I am going to have my mechanic install it because I just don’t have the time and he is second to none in my area.

 

Glad I can help man! Driving up to our camping spot in the mountains in Utah right now. 190 miles in and the ambient temp has been 75-80 and my transmission has been pegged between 180-185 the whole way so far.

 

Wow that’s pretty cool with all things considered.

Thanks again. I will feel much better after installation. Personally I never enjoyed owning a truck as much as I do the Tundra. Want to keep her running for many years!

 

Any reason you can't simply use the Setrab brackets?

I'm just about ready to pull the trigger here, just the bracket holding me up and no means to fabricate one myself.

 

No reason other than cost. I used the bracket from Setrab also but I still had to get some zinc plated slotted steel flat bar to mount the bottom of my oil cooler to the radiator support.

 

Possible that you can get some pics for clarity under the truck to see what you came up with?

I've got all parts in my cart with Fred Anderson (Thank you for taking the time to do that) just working out the mounting details.

 

It's 100 degrees outside my house right now and I'm not going to take the front off again but here are some pictures to give you an idea. The top bracket I mounted it to where the factory passenger side horn is. All you have to do is pivot the horn 90 degrees. Then the bottom of the bracket, I used zinc plated slotted steel flat bar and bolted to the center and bottom radiator support. Hope this helps.
