Going to replace my oil cooler, deltas are getting too high on the stock one that's in it. Any recommendations (I am not spending $1000+ on the BPD stuff, just looking at the high coolant flow ones on Ebay), I know to stay away from the Dorman products but on some of them (say CNS for example) it is saying that you will have EOTs that are higher than the 15 degree delta, does this matter? Or are they better with the enlarged coolant passageways because they are much harder to clog up......


this is the one I am lookin at:

You get what you pay for, and in this case you will pay for future headaches, that's a promise.
I suppose if one enjoys taking things apart and doing them over then go for it. I wouldn't buy that kit even if I was trying to pawn my 6.0 off on somebody.

Any time some Huu flung dung aftermarket claims things like having a 15* or higher delta, run for the hills. It doesn't matter how big the passeges are, deltas are deltas no matter how you slice it.

Go with this one and be done with it.

Any recommendations in the under $500 range?

 

Ive used that same kit at work, just make sure to get the FoMoco gaskets, the ones they come with are crap, they started leaking in less than 10k miles (specific the oil cooler cover the rest were still good)

 

From the ebay add.
That makes no sense. So they are saying that enlarged coolant passages are a good thing, and that Ford knows nothing when they say 15* does not apply here. Logic tells me with larger "passegeways"(this sound like Chinese converted to Engrish) my deltas should be 2*
Is this a magical oil cooler?
Have we stumbled upon the final solution for oil coolers for the 6.0?!
Hallelujah! and only $52 plus FREE SHIPPING!

 

haha, that's exactly what I thought....more coolant pumped through equals higher oil temps????? So basically the factory one is the way to go, I just need a good solid replacement that does what it's supposed to

 

My understanding of the high flow coolers is that both the oil and the coolant are being pushed through at a much higher rate so you do not get the convection cooling effect from the cooler. Much like a large pot of water on the stove takes longer to boil than 4 smaller pots with the same heat being applied. The updated Ford parts are you're best "drop in" bet.

 

For $52.00 I would think they would cut one in half and show the potential buyers those extra large cooling passages
For my money I'll stick with the Ford upgraded oil cooler....if I ever need one.

 

Larger passageways could mean less passageways resulting in less efficient heat transfer.
Since the sole purpose of a 'cooler' is to COOL I would suggest going with Ford oil cooler, or do nothing if you want to avoid spending your money (now). Save some $$ away each month so IF you have a future failure you can fix it correctly ONCE.

 

Somebody that actually is reputable (IPR?) was making a high flow cooler that fit in the stock location (there IS only so much you can do in that space), but they clearly stated it was not for towing, or towing much anyway. Ford actually ADDED a row to its cooler some time back to Increase the heat transfer.

That shows you what their thinking on the subject is. I went with the updated Ford cooler myself...

 

Like Misky says above, larger passages means fewer passages. There is only limited amount of space unless you redesign a taller cover. As far as the EOT/ECT comparison, once its redesigned, the heat transfer rate from the old design doesn't relate to the new. 15° is out the window. Nothing bad about any of that, just how stuff works.

I would point out however, that Ford (or IH) did a redesign of the oil cooler a few years back. The issues with the origonal design were well known by then and they ADDED a row of passages. Apparently, increased cooling effenciency was higher on the priority list than resistance to clogging. The high flow coolers tell you before you buy that the heat transfer rate is lower, just the opposite of what the OEM considered important. I'd be willing to bet some significant dyno time and testing was involved in the OEM upgrade, the high flow units don't specify a maximum number at all, it's not tested well enough for them to give us a number to determine when the part is bad.

It seems to me there are a few of these trucks that have corrosion issues in the cooling system. If you have one of those trucks maybe one of these coolers could help save some money and headache for you but if you have a "normal" 6.0 I would stay with the OEM part and I definitely wouldn't use one just Because they are cheaper.

 

Heat transfer depends on a huge number of factors, including some black magic, but in general more surface area means more heat transfer, especially if the 2 fluid temperatures are very close. Flowrate can increase heat transfer to a point as well, but in this case that obviously isn't the case as they are advertising higher oil temps.

For a water cooled oil cooler, you can't get any better than the stock one. Get your cooling system clean via flushing, add a coolant filter, run silicate free coolant (ELC) and you shouldn't have any plugging issues with the stock cooler.

Next step up in the air-cooled like BPD, which gets to be $$$.

 

FYI; I had to leave this here for those of you that refuse to believe that there is a decent aftermarket cooler.

I used the following "re-manufactured" unit the last time I had to change my oil cooler. I was strapped for cash, as I had many problems to remedy from a previous owner.
Product Detail This is $133 at rockauto.com

In addition to this cooler, I have also installed ELC coolant, a mishimoto 200 deg. thermostat and have an EGR delete kit on my truck. I NEVER see more than 9 degree deltas with the cardone unit, even while towing. However, while this may sound great to some, it does have a drawback. The blue o-ring that came with the kit for the oil cooler adapter plate should be replaced right out of the box. Mine lasted a week and began to pour oil out. I replaced it with a international sourced o-ring and it's been great ever since.

 

This is specifically a Dorman cooler but...

 

I have a new in the box oil cooler up for grabs if you want it. I bought it a few years ago as a kit when i did my egr cooler. Had it set aside , but ended up going for the BPD setup. I will never need it and is taking up place in my parts box.

I was told from the seller it is a Sinister oil cooler. I threw the gaskets away (they weren't OEM) so you would still have to get those.
