Kicked myself-need help with PS and tranny cooler line routing

[69LC]

As the title says I’m trying to reassemble my whole new radiator support and can’t recall how the oil lines go.

No I don’t have a FSM. I need some pics.

Can anyone help me out?

Is the rectangular cooler in front of the condenser for the PS or tranny? I have a second one I thought I was adding on the right for the PS and have 3/8” SS lines to run to the extra cooler.

I’m trying to eliminate the lower front X-member cooler line as it was rusted out when I bought the truck.

1st one is a mistake. I'll delete later.

The 'paperclip' hard line is the power steering cooler. The smaller square black radiator or heat exchanger is for the trans.
I see now that those pics dont help much as either of things things are in them. Oops
Maybe I have another better pic

 

[69LC]

That’s what I thought. Thank you sir! No need to delete pics. They both were helpful with the placement of the small hard tube fixture on the lower right (driver side).

I would not run those two tranny coolers up front, you are going to over heat, get a Derale one for $25.00 and put it down lower , yeah I know the stock tranny cooler is huge but you will have other issues JMHO

Starting from the solid lines that lead back to the trans which are routed on the drivers side of the engine: Top line is from the trans to the passenger side connection of the lower radiator tank. Fluid flows out the port on the driver side of the radiator and into the lower port of the trans fluid cooler which mounts in front of the AC condenser on the drivers side. Fluid is then routed from the upper port of the fluid cooler to the lower solid line beside the engine block and back to the trans.

The paper clip looking tube is the factory PS fluid cooler. You can either pick up a used one that’s not rusted out or install a different sort of cooler in the same location. A good many of us have installed a heat sink type cooler in that location with good results.

Yeah like the Derale one I posted

That’s not a heat sink and much more fragile. The OP lives in Michigan where hot days are few and if the 80 won’t be pushed hard off road with over sized tires, a PS fluid cooler probably won’t be necessary anyway.

Here's a link to the FSM.

Ok, so here is where I am tonight with replacing the “paper clip” line with 3/8” SS lines. I have to finish them tomorrow to bend forward and up to the added cooler. This will allow me to utilize the factory tubing clamps up to the point where the new lines kick forward.

Time for a cocktail and bed...

 

[Rivman1243]

Looks good!

 

[69LC]

Thanks. Bending line is one of my more enjoyable things to do in my work.

 

[Rivman1243]

What do you do for work?

 

[Kernal]

Educate us on how you bent those lines, material used, wall thickness, where to purchase, tools needed, etc,etc. More of use will need those skills as the years go by and parts disappear.

 

[69LC]

Well, it’s a long story, but to keep it simple:

.035” SS tubing. The bender is a nice Ridgid brand unit probably in the $250-300 range, but less expensive benders would work.

I buy scrap tubing from my work. It could be sourced pretty readily I’m sure, but we get it from large industrial suppliers. We build food grade filling equipment so the materials we use must be of certain industry standards.

I learned to bend just by doing it.

 

[Peluo]

I would pay you for a set what other benders for less money? I have one for copper tubing, would that work. How would you do the lips at the end of the tubing?

 

[Peluo]

Why not aluminum tubing and have the ends TIG welded with AN fittings? Or have the SS tubing TIG welded with AN SS fittings? Do AN SS fittings exist?

 

[69LC]

I’m using Stainless because I have scrap for $.50/lb.

I would have to look around at the fittings available. We use Swegelok or BiLok fittings.

I’m going to see if a spare chunk of tube will take a bubble flare. If it won’t I’ll TIG weld a small bead at each end.

I build, install and service bottle filling equipment for Fogg Filler Co. and work in the 191st MXS Aero Repair shop at Selfridge ANGB with KC 135T models.

 

[69LC]

Ok, so I’m not completely happy with the lines, but they will have to do. I have lots more work to do on the truck.

I borrowed a nice hydraulic flaring tool from my NAPA and discovered a bubble tool set that worked pretty well. One of the bubbles got a bit sideways, but it will suffice.

The lines need a couple of more tweaks tomorrow. They mostly fit. They will fit...
