I disagree with bending the hose 90 degrees.

I didn't say bend the hose 90°. If you will read what I said, it was based entirely on the lack of room. However I would much rather have a smooth unkinked hose radius than a 90° fitting in that location. I was merely answering the questions asked and pointing out the obvious. Personally I think every method that has been discussed is backyardy. But that is another discussion.

[quote If anyone out there knows where to find a 1/2 x 3/8 elbow in a brass barbed fittings, that would be the best way to insall these coolers, that would require no threaded fittings. I did not like the idea of bending the hose 90 degrees coming off of the cooler, that is why I elbowed as soon as I came out of the cooler.Thanks[/quote]

You could use this a few inches of 1/2 in hose on the outlets of the cooler
Then connect this 90 degree 1/2 elbow barb fitting Bronze Hose Barbs: 90° Hose Mender

Then connect 1/2 line to that elbow, run the line back to toward the 3/8 lines and use this union reducer to go down to 3/8 Hose Barbs: Hose Mender

Now you have no threaded connections, a 90 off the outlets of the cooler and a simple reducer back to the 3/8 lines.

I've been on the search for a barb elbow that reduces but have yet to find one, it might be out there.

You will have to go to someone that specializes auto air conditioning parts. They will have a 13/32" to 1/2" elbow. A 13/32" barb works fine in a new 3/8" hose.

I have looked I was unable to find one either. Thanks

I did not feel like there was adequate room to let the hose bend in a gradual 90 degrees, without forcing it abit, so that is my reasoning for the 90 degree elbow,and I could be wrong, yes I was concerned about restriction too, but after about a 100 miles on the freeway at 75MPH my trans ran a lot cooler, yes when I get my 5ver at 13000k hooked up in the summer things might be different. What troubles me the most about your thread is the backyardy comment, I think everyone including me would like to hear the correct way to install a 6.0 trans cooler, thats what I thought this forum was all about, if everything here is backyardy, the last thing I would want is someone to lose a transmission because of bad advice, so I am more than happy to hear anything you have to say that makes this conversion correct. Thanks

I guess I'll give my Backyard findings on fluid pressure loss with 2 90 degree elbows used in the system

Take it for what it's work by Gates has a calculator for pressure loss and you can plug in as many fittings as you want into the calculation. I'll be honest I don't know if my numbers are all right. I used 2 gallons per minute, for flow of our transmissions, and looked up the values of mercon V for viscosity and specific gravity, used 4 ft of 1/2 in hoses. I got a pressure loss of 1.5 psi with 2 90 degree fittings.

And here is the calculator to play around with if you want to
Fluid Flow Calculator

Honestly I don't think that two 90 degree fittings are going to make a difference in flow that will effect cooling characteristics. Think about how many fuel systems that are built for race engines that use stainless lines with 45 degree and 90 degree bends, or how many bends there are in the HPOP system. I'd be willing to bet two 90s into the cooler wouldn't make a difference. The fluid is still going to be pushed through the cooler regardless.

Go ahead and give me a hard time for being over technical on the calculations

I think the way we are doing it will work just fine, yours being less fittings, my thinking on using a brass elbow like I did was that the brass 3/8" threaded elbow was larger in size inside nearly 3/4", which might help cut down some of the restriction, but I am probably splitting hairs here. After hearing all of this what I am going to do as soon as I get a chance is I am going to have a hydralic shop build me two 1/2 metal lines with as gradual 90 degrees that will fit under there, then have them install a short piece of 1/2 hose to each end one to the cooler and one to transtition to 3/8, unless the have a way to neck down the metal line to 3/8. After saying all of this, I am still waiting for a reply from 444-4D on the backyardy comment, in hopes he can set us straight on the correct way to do this, and save us all some time and money, but so far no reply. Thanks

There's the problem. It will cost more and take more time to do it right. Someone was even concerned about the price difference in 1/2" and 3/8" hose.

I am still waiting to hear a reply from 444-4D on the right way to do this job. My comment about time and money, I should of explained myself more, I DO NOT want to see someone do this upgrade twice, thus more time and money. I was told long ago if you don't have time and money to do it right the first time ,when are you going to find the time and money to do it twice. I am not concerned about four feet of larger hose or was I ever. I repeat I am only interested in doing the upgrade correctly, So if you feel like you want to set us straight, so we can do a trouble free upgrade , I am here to listen. Thanks for any help you want to share.

What year is your truck?

 

[detroitfd]

LOTS of users here posted pics of their upgrade to the 6.0 cooler, and LOTS of them use the elbows. I haven't seen anyone eat a trans after this and then warn against it. I'll be watching this post tho, as once the weather clears here, my cooler will be going in.

Who said using an elbow would ruin your transmission?

 

[detroitfd]

Um, everyone is talking about the restriction the elbow causes. Concern was for if this is a good idea. That's all. I was just saying it seems like everyone uses the elbow with no problems.

 

[up2nogood]

What year is your truck?

Early 99. My transmission is cooled by a cooler only, does not run thru the radiator

 

[444-4D]

Give me a couple days. I'll see if I still have the part numbers of some stuff. Are you willing to spend a couple hundred bucks on hoses?

I am willing to do whatever makes this right, I have to assume you have not installed one in your truck ????????????? Thanks

I'm sure you know the cliche. But be cautious what you assume.

I knew that was coming:lol:

why would you have to spend a couple of hundred dollars on hose?

I have no idea, but I am sure 444-4D is going to enlighten us:read:
