In Radiator Trans Cooler for Power Steering?

This isn't completely jeep related but could be the same on jeeps. My s10 pile has a manual trans so i don't need a trans cooler in the radiator but i have a radiator from an s10 with an automatic that has the trans cooler in the radiator. Can i just plumb my power steering lines into the radiator mounted trans cooler or is this a bad idea? With the front spool and hydro assist i'm going to need a power steering cooler. Using the radiator with trans cooler will cut down on "stuff" on my pile instead of a seperate cooler.

Run a seperate cooler in front of the rad. That has worked fine for me and a bunch of friends. I would never use the cooler in the rad for this application due to the high heat(180-210) to begin with. It's just too hot for the PS.

Ok, what about one that goes along the frame rail or some where else? I don't think i'm going to have much if any room in front of the radiator.

Better than nothing, but not by far. It needs airflow to work. And being on the frame it will get packed in with mud in no time rendering it useless.

Re: In Radiator Trans Cooler for Power Steering?

Andy,

I have a Buick 455 and am using a radiator from a 95 Dodge diesel. The rad. has 2 aux coolers (tranny and engine oil).

I was using the aux for front steering (full hydro and 44's welded rockwell) and for the tranny (THM-400).

The tranny was getting hot so I pulled it from the radiator auxillary cooler and ran a seperate cooler right behind the grill. I still run the front hydro in the rad. with no cooling issues. I have a mechinacal fan behind the radiator and a Tauruas fan in front of the radiator (behind the tranny cooler). (will post pic's in a day or so of all my progress on the Jeep, lot's of stuff going on here)

The rear steering has a cooler tied to the rear tube cage with no fan and it never gets hot to the touch.

On the CJ I installed an auxillary cooler for the steering (welded front). When mounted in front of the radiator the steering overheated. When mounted behind the radiator, it stayed cool. Either way, you will most likely need to add an electric fan to the mix....

What about a 10' or so piece of steel tube ran in a loop down the frame rail or something like that? I know that's what GM gave my 3/4 ton from the facotry for a power steering cooler.

Yes! and look how well GM is doing!

Sorry, I just had to, I'm a Dodge guy [img]/ubbthreads/images/graemlins/wink.gif[/img]

From the factoy, my Ram 1500 4x4 has a power steering cooler mounted to the crossmember behind one of the big vents in the front bumper. It looks like a mini aluminum radiator, I think the tubing makes 5 passes through it. I doubt something like this would cost much from Jeg's or one of those places.

Aside from the crossflows that use both tanks to cool (one oil, one trans), the tank cooler is always on the outlet side of the rad. If you're at those temps (not so much the 180 end as the 210), you're not operating the engine at the spec'd temp. That is, you're on your way to overheating.

Liquid to liquid coolers are far superior to airil coolers in terms of heat transfer. Even at a much lower differential they will transfer more btu's. LSI's use the lower rad hose to cool the PS ..as do Crown Vic for the oil.

Using the rad tank is far better, IMHO, then no cooler at all (in situations where the PS is stressed).
