I’ve been working on three projects up front in prep for Sand Hollow:
1. Setrab Transmission Cooler
2. Improved Racing Thermal Bypass
3. Hydro Assist
I moved the Setrab transmission cooler from the Red Jeep to the Silver Fox because it’s my DD and doesn’t see high temps when not wheeling. Plus, it and all the accompanying parts are pretty expensive and I may be selling it at some point.
With Blaine’s Nearly Bolton Hydro Assist I got his new V-Bar so I could install the Derale steering cooler and Setrab transmission cooler nicely in the grill. My temps got up to 250*F in the Moses Lake dunes last summer, so I need a cooler for summer wheelin. It was a pain as usual removing the grill, but mainly because of my turn signal and side marker light wiring. Blaine’s kit comes with some nice well nuts to replace the four you destroy getting in there. The lowers are replaced with the thick ones to keep the lower bolt on the V-bar from rubbing the AC condenser. He thought of everything, even the same size head bolts as OEM and 3 replacement fir tree fasteners. Lots of detail. Nothing overlooked.
Then I went to install the Improved Performance thermal bypass for the transmission. It’s the compact version with -6an fittings and opens fully at 165*F. It gets so cold here that the temperature gauge usually doesn’t even read on the gauge because it’s under 100*F. With the Setrab cooler that’s doubly sure. Blaine sent me a list of all the fittings I would need. Here’s the thermal bypass and the fittings.

Blaine prefers the Insta-grip hose that he uses on the steering coolers and I bought some from him because I could only find it in large quantities for around $2,000.
It’s scary (for me) cutting the transmission hard lines, but used a small cutting wheel and got it done. Then I realized with the spacing between inlet and outlet I needed the transmission lines farther apart. That meant the lines were not equal length anymore, so I had to cut one of the lines again. Built an aluminum bracket basically mimicking pics of Blaine’s. It turned out good. Then routed all the hoses from the bypass to the radiato out to the Setrab and back to the bypass.
Next I started working on the Hydro Assist. I’d already installed the steering Cooler on the V-Bar so I installed the new pump. Blaine sent an M8 1.25” bolt for the one replacement that is no longer a through bolt.
My steering box was still at PSC so I was waiting. It gets here tomorrow. It should be the last piece. Meanwhile I tried to find a place for the PSC reservoir. Fortunately if left a space on purpose when doing the HiLine fenders. The distance is about 11-12” and it’s above the pump. I routed the hose in a way it would have some slack under engine torque.
Then I test fit and built as many hoses as I could without the steering box.
Somewhere along the way I was working on the PSC steering cylinder mount at the axle. You have to beef up the bracket. Blaine sends that in his kit. Weld on when you’re happy. It may need a little modification. Mine did. Worked great. If you have a midarm you have to make a strap to support the backside of the bracket and it’s basically a 2x7”x1/4” steel cut specifically to shape (it’s very close to the spring), and then you bend it like a lazy S to fit. Took awhile with a hammer and vice. Drill your 1/2” hole, put the bolt through with the spacing cylinder, and weld it in place.
There’s a snazzy bracket Blaine sends with his kit for the drag link side of the PSC Cylinder. I ground down the drag link and painted it and the bracket days before so it was fully cured. It’s going to be perfect.
Now I’m just waiting for the steering box to arrive tomorrow and I can get it back on the shaft, bolted to the frame, and reinstall the pitman arm. Then I can test fit and make the hoses and run them to the box. At the end of the day I’ll be able to bleed the system. Just praying no leaks and everything works.
