Hayden 698 transmission cooler install with custom brackets.

[95Z28A4]

I just read a thread on this site where a member was requesting someone manufacture custom brackets to mount a transmission cooler directly to the radiator support.

3rd Gen 4runner External Tranny Cooler Install w/ Radiator and Thermostat Replacement

I decided to share photos of the brackets I made to install a Hayden 698 in my son-in-law's 1997 SR5 4Runer. The brackets are made from 1"x1/8" flat bar and 1/8" plate. The bracket near the headlight is one piece. The bracket near the center is made of two pieces and welded together. I used two bowls to form the inside and outside radii of the curved piece. The bowls are 6-1/4" and 8-1/2" respectively. The top of the bracket near the headlight is attached to original passenger side horn mount with the original bolt. The rest of the fasteners are 1/4" bolts. The bottom of the center bracket is attached to the radiator support with a 1/4" rivet nut. Providing you can weld, these brackets are not difficult to make.

Like many others, I relocated the passenger side horn to the driver side. Instead of extending the wire, I pulled it from the loom.

While I was at, I replaced all of the transmission hoses, because the originals were becoming mushy.

They make a ‘zip tie’ that holds it on as well. Goes in between the fins of the cooler and radiator.

Ran that for years before I found a 5-speed to swap in.

Looks good! Also, note that you are missing the bottom part of the fan shroud. this part is still available to purchase new or get one from a yard. this will also significantly help the fan to pull air THROUGH the radiator than from the open area.

The cooler came with a set of 4 zip ties. I used that method for mounting a transmission cooler in a Jeep Cherokee about 20 years ago. I didn't like it. I've fabricated brackets for every transmission cooler I have installed since then.

I did not realize there the shroud has a bottom piece. Are you talking about part #16702? Do I need part #16702A to install it?

16702 is the lower shroud. You'll need 2 of 16702A to attach it if I remember correctly.
