power steering cooler
Hi everyone. New owner of a used Aerostar here.
I have a '94 AWD shorty with the tranny cooler behind the bumper and the power steering cooler tubing in front of the condenser.
Have other drivers with the standard tranny cooler found it to be adequate? The tubing for the P/S cooler is starting to corrode. I was toying with the idea of cleaning out the tranny cooler, hooking up the P/S lines to it, removing the tubing and then installing a heavy duty tranny cooler in front of the condenser.
Does this seem feasible, or am I missing something potentially catastrophic?

Welcome to the fourm!
I don't know of any stock tranny cooler that is adequate on any automobile. I installed a huge Hayden stacked plate cooler in front of the condenser, then ran the fluid to the stock cooler. Oh yea, I also installed a Magnefine in-line filter before the coolers. Have one on the PS return line, too.
Your ideas sounds excellent to me. Might do that myself.

I recently put a hayden tranny cooler rated for 10,000 lbs AFTER the stock tranny cooler. so my tranny fluid goes through the radiator cooler, then the auxillary cooler (stock) then the hayden. it works great. I would like to get a tranny temp gauge to see exactly whats going on there, but have not yet.
I was not aware that power steering even needed cooling. but i guess its like anything else, the cooler the better.
I want to get a dual oil filter adapter/relocation kit, and an engine oil cooler too.
I want my 4.0 to last forever!

I've also wondered about the ps cooler..But they wouldn't have ever put if there if it didn't need to be there - I would replace it, I would NOT remove the tranny cooler, the bigest enemy of an auto trans is heat - this is VERY true on the aerostar! - they are well known for over-heating related tranny problems - i would be more inclined to add an another one.

I recently replaced my PS pump and all the lines, hoping to get rid of most/all of the whine. Didn't work, but what I did do was put the lightest tranny cooler we had in place of the stock ps cooler, works great, barely gets warm. (p.s. "we had" is because I'm second assistant manager at Advance Auto Parts).

Hey Guys and Gals:
I just had a brain storm or should I say I just thought of something that has been staring us in the face. Since the transmissin over-heating seems to happen mostly in the Summer time and most of us use the Air Cond..........
Here it comes.........
Why can't we take and put a bigger piece of metal/copper tubing in line and tie/hook it to the pipe that ices/freezes up that comes off of the Air Cond. That should cool the fluid as it passes it.
Or better yet wrap some copper tubing around the outside of that pipe.
What do you think????

JT,
Actively cooling one fluid means you have to work harder to cool the active cooling fluid. In this case, the AC compressor is going to work a little harder, and the extra heat will end up back in the front of the engine, coming out of the condensor. It will work, but it will generate more overall heat, since the condensor has to do all that extra work.
What might be more effective with less work would be enclosing the cooling coil in a water jacket, and plumb the engine coolant through it. This method is often used for cooling where there is no space for a full size oil to air cooler. It even works for transmission cooling. You just need a really big radiator to accommodate the added heat.
