Hemi Swap Power Steering PSI Reduction Toyota Valve Mod and Radiator Power Steering Cooler

- In this episode I address some power steering problems I've had since I finished my 5.7 emi Swap of my 1970 Dodge Challenger. I pulled the valves out of a Toyota Camry and a Lexus to attempt to re-valve my Gen 3 Hemi's power steering pump for a lower PSI. I also re-purpose my radiator's automatic transmission cooler to run as a power steering cooler for my setup.

It was really cool to see all the research and development you went through to make this work
That was a lot of work 😳 I used a AT transmission cooler for my PS but when I used to road race hondas, I ran my PS lines through my radiator like you and then through the stock AT cooler(I had converted mine to manual.)
Ever notice any issues running through the radiator? I think I saw a very slight increase in coolant temps but I haven’t gotten around to sealing my fans to the radiator yet so that should bring them back down.
@@noboltsleftbehind well yeah, that is a slight consequence but your cooling system should be able to handle it
Just found your channel....very nice job in your explanations and I really enjoy all of them!
Thank you sir!
Good idea to use the AT side of the radiator
Love the ingenuity
Dang talk about problem solving! Nice job
Thanks!
By far one of my favorite resto-mod dodge.
Awsome work, love this car !
Thanks man!
Very creative using your radiator like that. Is a too low temp of your fluid not an issue for the long term?
Respect for the solve man, really thinking outside the box.
From what I read an ideal power steering temperature is right around 160-170, so I should be right in the sweet spot. The power steering actually uses auto transmission fluid which is what the radiator was built for. We’ll see what kind of temps it can hold it at when I do a track day soon, but I’m hopeful!
@@noboltsleftbehind sounds perfect! Let's hope track day goes well 👍
Anyway I think there's like 18 different pitman arms that'll fit in there into the old original 1971 power steering gear box for a Dodge Challenger and it's almost unsafe it's so touchy because you've only got an inch play in the steering before your wheels totally turn
I remember thinking wow$159 this is way too much f****** work 😂 and they all agreed this is bulshit man. Ha ha ha the headers and intake. Yes that how we'd do'em they said. And they got 10 different ways to make that part for the throttle linkage now that I had them custom weld together from the linkage to tie the cable for the transmission into working order
But I screwed up when I pulled the steering column out of the car steering wheel and I couldn't get it back into the gearbox by myself like I could pull it out of your box so I've got it shoveled about a little bit of the way in or it's almost in the right position where you need to put that cotter pin by that worm gear ⚙️ and then I just squirted silicone in the whole to grab it😂! Ha ha ha 😁🤣 but I asked him for an air hammer so that I could beat it back in the position they wouldn't give it to me LoL thankfully 😂❤
I'm doing Hemi swap in a 69 coronet wagon. I got a 74 challenger radiator, to have to hose outlet on the right sides, what hoses did you use for both radiator hose. outlet to the t stat is 1 3/4 and the radiator is a 1 1/2 inch. lower is 2" on the engine and 1 3/4 on the rad. the Hemi is a 05 just like your .I'm doing the power steering now like you did yours. I got the pressure valve yesterday and get the pump and pulley today
Coronet wagon! Super cool man, absolutely love those and such a rare car to see. Part number for my upper rad hose is E 72210 and Lowe hose is D 70685. Hose diameters were a little smaller than some of the outlets but I was able to stretch them on. I’ve put about 10k miles on them they’ve been just fine. I’ve put a few thousand miles on the power steering (including some hard driving at the track) since this modification and it’s been great, totally solved my issues.
@@noboltsleftbehind I'm did the same mods on the pump as you did, just waiting for a pulley (I ordered the wrong pulley the first time). Your info was spot on! I'm putting in a vintage air system in the wagon . I want to us the factory pump off of the hemi , so I don't have to modify the mount , I am looking for the compressor fitting and can't find any, would you happen to know if they are available and if so where. Thanks for your help
@@davecantu7437 awesome man, so glad to hear I could help! I did the same, I hooked my factory Hemi AC compressor to my vintage air system. Vintage Air has the fitting you need, they’ll build the hoses for you too.
Where did you get the PS reservoir from? Looks nice!
Thanks! I found it at Speedway Motors
can you share the year range of toyota/lexus you dealt with? seemed like it was mid 2000s but not sure.
I don’t know the exact years, but I was finding the pumps mostly in mid 90s - early 2000s cars.
what is the brand and part number for the reservoir doe it come with the fitting for the pump?
It's a Speedway Motors reservoir, part number 91032876-STD-8 . It comes with AN fittings
So the first thing they did is pull of the header off there that I bought and heated up and doik it like you press in on a clown nose LoL an that wasn't enough clearance really so they took apart the gearbox and went through all of the different pitman arms that were available that could possibly fit inside of there until they found one of them that gave enough clearance to allow the car to turn left and right 👍 and be far enough away from The hitter so that you know this is actually functional instead of like a drag car or a NASCAR
Why didn't you got with a LS Type II? I believe there are some out there that work with a Borgeson box. I am going to be running a Holley Type II with my 5.7 in my Charger.
I was too cheap to buy the Holley kit lol and I couldn’t find a way to adapt the LS type easily. That would have been my next step if the Toyota valves didn’t work out.
@@noboltsleftbehind Completely understand
The holley kit is super nice. I have it on my hemi swapped D100 but was looking at doing the Toyota valve also. DIY Hemi has a full video also on what valves make what pressure
@@repair-and-despair-garage the DIY hemi video is where I got the idea actually, definitely we’ll explained. I’m not 100% convinced the PSIs they have listed are quite right, one of the valves I scrounged was supposed to be like 800 or 900 psi and there’s no way it was that low. I suspect it was less to do with the valve letter and more to do with the little holder nut the valve sits into. I noticed they have slightly different sized fluid passages.
I think you are right. Not long ago I messaged them about the valves and they were experimenting with another setup off some other Toyota at that time because they weren't happy with the results. Still a neat way to do it though
😊ha ha ha 😁🤣 yes something exactly like this went down just switch to hooker headers and they bolted to the block just fine but then the steering linkage at the pitman arm touched the headers and when you turned it to the right it would pull an touch them and bend the headers away from the block at the top!
Will this work for a hellcat power steering pump.
The Hellcat pump does appear very similar to the 5.7 so I think it probably would work. Just make sure to double check its stamped Toyoda.
And I noticed that one of the key differences between the 71 and 72 Dodge Challenger which my 72 is almost a total 71 clone is the windshield wiper motor motors ha ha 😅😉 and how they look and bolt 🔩 in place on the car I think where you sit 🪑 in the back seat and the roof are still 1972 dodge challenger but it's about nine cars all 1971 rt dodge the trunk deak lids not no wing but he even had the vin plates and pictures from when my car was a total rusted out piece of crap!
