Transmission Cooler Bracket Kit - Hayden 679 / 689

It looks like the 679/689 are the same in size as the 699 with the exception being the height and length are switched.

When adding a cooler to the 2019 - 2021 years, you add the OEM thermostat. The thermostat gives you the temperature regulation as well as the inlet/outlet barbs.

The Hayden 699 has a built in thermostat essentially. This would be redundant in addition to the OEM unit that gets installed.

The Hayden 699 is rated the exact same as the 679 and 689 for towing capacity (10,000lbs) and GVWR (22,000lbd). I’m always open to thoughts and improvements, but I see no difference expect the extra thermostat in the 699.

 

Initial post updated with a new bracket for the 2011 - 2018 Tundra and 2011 - 2022 Sequoia with 5.7L.

Also, I have one bracket kit left that uses the 679 Hayden cooler for the 2019 - 201 Tundra. If you want to use a

$58 Hayden 679 Universal 11” Rapid-Cool Add-On Transmission Cooler to Enhance Cooling (not for direct replacement of the factory unit)

Hayden 679 cooler I can offer a discount on the last kit.

The new redesigned bracket is a multi-fit and fits both the Hayden 679 and 689 cooler.

 

Hey @Jmunk will this work with the Magnuson 2650 supercharger I have on my 2021? Not sure how is all going to fit in the front? I am interested in this kit for sure.

 

I haven’t tried one so I can’t say for sure. If you have a photo of your truck with front grill off I should be able to verify fitment from that.

Any of you fellas run the 3/8 rubber hose all the way and not use hard lines in the middle? I was gone wrap them in a protective cover that they use on heavy equipment hydraulic lines. What you all think

 

I have (1) discounted bracket kit left for the 2019 - 2021 Tundra for a

$58 Hayden 679 Universal 11” Rapid-Cool Add-On Transmission Cooler to Enhance Cooling (not for direct replacement of the factory unit)

Hayden 679 cooler only. This is the last of the first design before they became multi-fit for both the Hayden 679 and 689. Discounted to $80 shipped (powder coated bracket and hardware kit) - these fit the Hayden 679 only. If interested send me a PM.

Also, I just picked up another batch of the 2019 - 2021 Tundra brackets for the Hayden 679/689 cooler from the powder coater. Feedback has been great on the kits sold.

 

I got the bracket yesterday; the Hayden 689 should be arriving tomorrow. Hoping to get it installed by next weekend. Will stop by the dealership to buy the fluid this week. Seems like a sturdy well made potency!??

 

Glad it made it safe. Share some pictures once you get it installed!

 

will do; waiting for parts from my Fred Anderson order too.

After more and more installs I prefer a 90 fitting on the top and bottom port. This photo shows my preferred grommet placement in the wind deflector.
