Good evening,

what do you guys think about this solution? I've often wondered why a cooling system has to be so complicated like in the 6.0. Of course, the EGR system is significantly to blame for the developed system with its many sources of trouble.

Alternative solutions are often discussed in Facebook groups. Of course, I am cautious about the claims made there, but I find solutions that eliminate potential weak points for leaks interesting.

What do you think?

The primary question for me is to what effect such a conversion would have on the ECT and EOT?























Ideas?

 

Interesting concept, my first concern would be with the heater hose. Some, like mine, have rhe control value that could and would restrict flow. I think it would be better routed to the heater return line, with proper shielding from the exhaust system. But I see this a fix for a problem that doesn't exist and easily causing way more issues. Just me though.

Again Interesting.

Reread you actual question, i dont think it would be good for the deltas. Probably make them worse.

 

I’m not on Facebook, but what are the “claimed” benefits of this and I’m curious what the kit costs and the time to install. It does look like a kit the way everything is bagged.

 

At first glance, I can't see any advantage just because of the changed circulation.

Supposedly, this would result in a better delta.

I see the advantage that there are fewer potential leak points.

I would of course make such a kit myself.

He wants $500 for it.

 

The consistent concern regarding leak points with the stock system was the old hose used between the oil cooler and the EGR cooler, and within the EGR cooler itself. The newer hose, and for the wavy oil rail vehicles, a BPD EGR cooler addresses that —well, better than some of the reroute klits that leak.

To increase the oil cooler's heat rejection efficiency, you would need to compare the flow resistance of the EGR cooler to that of the heater core and its plumbing. I remember when AKBlackfoot had his engine reworked, there was a cooling issue due to some rerouting of the cooler or the coolant filter, but I don't have time to hunt for that.

 

The more i think about this the more i question how does it lessen leak points. You have the front cover to intake and the egr input into the intake that will be back filled by the coolant system. You still have the oil cover outlet point. This eliminates the egr coolant inlet, but adds a tee connector at thr heater hose..

 

If the coolant doesn't go through the intake manifold, you can eliminate the hose that goes from the intake to the degas bottle. That can eliminate three leak points: both ends of the hose, and intake manifold to front cover.

I ran a coolant bypass for a couple of years. It went from the oil cooler, around the back of the turbo, and wye'd into the heater hose under the degas bottle. It was about 3.5' of 3/4" silicone hose in a DEI kevlar tube. Eventually the kevlar wore through against the up-pipe, and the hose melted against it and cracked, and I had a nice coolant leak.

I am back to stock-ish, and my deltas are where they have always been since my first massive coolant system flush and new Ford oil cooler four years ago: 10-13 degrees. I have tried all sorts of things to get them lower, but nothing has made a difference, including the bypass.

 

Guy is out of his mind. The key piece can be had on ebay for $15 plus shipping:

He's buying those, throwing in a tee and some hose clamps, and charging $500 for what, the idea? Even though they have been around for a long time. Total effing con artist.

 

I forgot that you had done that Chris.

 

Heck, I forget all kind of things these days.

One more point about the bypass: I would consider doing it again if I could figure out a way to run the line around the front of the turbo and into the side of the degas bottle where the line from the intake plugs in. (Think about how easy it would be to back flush the oil cooler AND eliminate three leaks!)

Unfortunately nobody makes an aftermarket degas bottle that a) doesn't look like an overpriced POS, and b) offers a 5/8 or 3/4 threaded port in the right side. And it also seems nearly impossible to fit a bulkhead in the stock degas for such a connection.

This is my attempt at eliminating one of the more problematic leaks. It's still doing its job after a year.

 

There was only one time I ever had a leak, and that was the original hose between the oil cooler and EGR. Once that was replaced with the updated one, I never had a leak.

 

here we are deleting every 6.0. In my opinion it would be a benefit to having no coolant running through the intake manifold.
But there my be a reason why the engineers did it like they did.

 

Thats the guy

 

I would be hesitant to have the oil cooler outlet flow go thru the heater core. Could reduce flow potentially. The flow going to the heater core goes thru the block first so it would depend on the pressure drop thru the block vs that thru the oil cooler.

Also with this setup you couldn't run a heater core shutoff valve as that would also shutoff flow to the oil cooler. Not a huge deal, just helps with the AC system. Or I guess flow could reverse and go back to the thermostat, but now you're on the wrong side of the pump. Sounds like a recipe for problems.

What Chris described above running to the heater return would be much better a setup as you're basically returning to the suction of the pump like the stock setup. But it sounds like it didn't help him at all.
