That looks like a good upgrade. Did you add a reservoir too? I really like the idea of more capacity. I ask because to 14" 2 pass unit holds less that a pint (14 oz.) and you said you gained a quart.
At the time yes but I’ve since remove it because it was leaking. I need to eventually throw a tig weld on it and put it back into use.

Observations on the extruded coolers: They tend to trap air bubbles, making bleeding difficult, in a couple of cases, have had to unbolt and hang upright to do the deed. On the trail, when stood up, so the pump is sucking air, the bubble that forms in the cooler displaces fluid, pushing it out the cap. Then when more level, some of the bubble works out, the fluid is low, so sucking air, again.
On a couple got tired of fighting them, replacing with a cooler that has tubes about the same size as the lines solved the problem. This type of cooler should easily flush/push all of the fluid/air through them. Best to have the inlet at the bottom, outlet at the top, flushes air the best.

Bumping this thread that I found while searching for info about the power steering cooler. Every time I come across a thread that Tools R US comments on I make a mental note because he was a very knowledgeable fella.
Anyone have any ill effects from running a stand alone PS cooler? I can see tool's concerns with the system getting air bound, but I'm curious if anyone running this has had any problems with it?

You know I mentioned his comment to someone, who said to me, IIRC: It's a sealed system, how can it get air in it?
The disadvantage I see is I don't know how you would put a fan on it.
You are correct that air should not enter the system when everything is fitted and sealed, but air will have to be purged after the initial install.
Tools mentions piping the cooler by supplying the flow to the bottom and returning it out the top to help with purging. My concern with doing that is that it's the opposite way it should be piped. If we were piping a heater like a fan coil, that would be the correct way to pipe it because Heat rises. Seeing that We're trying to cool the fluid as much as possible so it needs to be supplied in the top and returned out the bottom of the cooler. The cooler with the 3/8 npt fittings installed creates a small area where air can be trapped. This wouldn't be a concern if the cooler itself had a bleeder, but I don't believe it does.
Parts are on the way so I'm going to run with it and see what happens. I tend to over think things
This cooler doesn't require a fan and should provide more cooling than the loopy loop OEM setup at half the price.
The more I over think this.... I should be able to leave the cooler loose from the truck and hang it vertical with the in/out on the top. Fill/purge the system of air and then swing it into place and mount it. The two mounting bolts on the fitting side could be difficult to get to with the lines fitted, but I'll have a better idea when it's in my hands.
I got the cooler mounted and piped yesterday and I'm really happy with the way it looks. I was afraid it was going to look funny but it looks good. As I stated in my last post, purging air won't be a problem. There is enough room to get my fat fingers at the mounting bolts behind the fittings. After i finish up the rear end suspension ill get the PS filled/purged and ill snap a few pics of the process.
Looks great, did you just modify the lines from the original to this new cooler?
