Oil "fooler" as a PS cooler?

[JohnK]

Hey all,

I like the look of the oil cooler in the lower opening, but from what I've read an oil cooler is completely unnecessary on a coyote for street use. One option is to just install a 'dummy' for the looks (a.k.a. "oil fooler") but I'm wondering about using it as a cooler for the power steering? I'm installing a Unisteer PS rack with the KRC pump with integral reservoir, in case that matters. supply/return lines are normally -6 AN (I believe) for this PS setup. Would there be an issue with plumbing the return line with -10 AN lines for the "correct" look? It would require -6 AN to -10 AN reducers like these (https://www.summitracing.com/parts/fra-491914-bl), but other than the added cost of the larger cooler and larger -10 AN lines is there any potential risk to running a setup like this? Is it possible to overcool PS fluid?

Thanks,
John

I've done. it a few times, works fine

Great. Thanks Gordon.

This is a great question/idea. I’ve considered this myself as the oil fooler doesn’t sit well with me. I don’t like things that are for show only, though we’ve all made exceptions, I know. The PS cooler is a great idea that gives you the looks and is functional and, I’ve heard, might be required in situations like autocross. Gordon have you written your procedure up in the past? If not I’ll follow what you do, John. Thanks for posting this.

Really no specific procedure. Run a 13" wide x 5" tall -6 cooler, Use -6 adapters on the rack. Use -6 to -10 AN adapters on the rack, cooler and return fitting on pump. Plumb pump to pressure side of rack to cooler to pump.

I think that from a plumbing standpoint it would be very straightforward. The big question in my mind is how best to mount the oil cooler. I'm also planning to install Mike Everson's radiator shroud so I'd need to drill it for the two hoses to pass through, and then fab up a bracket of some sort. I'm guessing I can't do any of this until the body is on, so I'm a looooong ways away from solving the mounting question. If someone else has links on how they mounted their oil cooler in the nose, that would be great.

[Gordon Levy]

I'm not sure how well it would mount to mike's aluminum kit. It would need t be more ridged and squarer.

Why not add a cooler with a thermostat? So what if you never need it, it looks correct and is functional.

I mean you could have be a 100% fooler and it go to nothing...

Here is how I mounted mine. Its on the FFR part but same concept could be used on the Mike Everson radiator shroud. Its the Earls PN 41300ERL cooler.

It's not a 'fooler' if it's actually a (PS) cooler!

I have a small PS cooler installed in the oil cooler opening using Mike Everson's nose aluminum as well. In my case, I am supporting the cooler from a piece of 3/4" aluminum angle suspended side to side across the two lower 3/4" square tubes that extend forward to support the quick jack mounts. I know there are others who've simply added some reinforcement below the nose aluminum to provide a more robust mounting surface though.
