Our full prototype unit has arrived and is ready for some final test fitting! Before introducing our final product, let’s take one last look at the stock hose setup.

Now, check out the Mishimoto prototype kit!

A few interesting things to note. First, we have replaced several of the bends that were previously plastic with our silicone hose. Instead of incorporating the bends into the quick disconnect fittings, we are using the hose to make all the bends.

Also, the stock hose uses a double O-ring connection on the engine-side quick disconnects. On the radiator side, the stock still uses a single O-ring system. We use double O-ring connections on both ends of our hoses for better protection against leaks and to reduce the chance of air entering the cooling system of your 6.4L.

Our lower hose is still a two-piece unit; however, we are using an aluminum bead-rolled pipe for connecting the two hoses instead of a factory quick disconnect. Check out this connection point!

Next, we installed these in our test truck to check final fitment. Take a look!

Once the lower hose was successfully installed, we had a fully functioning silicone hose kit that fit perfectly. At this point, mass production of the hose kit begins, and we prepare to release an awesome product for 6.4L owners.

Thanks for following along with the progress of our build. We are hoping to launch a presale for this particular kit within the next few weeks! Stay tuned for more details.

Thanks

  1. I am very much looking forward to this being released.
    looks great!

    My 2010 6.4 has just recently started a slow leak from the bottom hose where it connects to the engine. The top hose is the new white double o ring style, but the bottom one is the single o ring black hose. When it gets cold there is a tiny bit of leakage I can see in the driveway.

    I think the ford blue hoses will look awesome.
    Thanks!
    Steve.

  2. This prototype radiator hose looks great. I thought it was interesting that you used the hose to make all of the bends, instead of incorporating them into the fittings. Would you mind telling me a little bit more about that?

    1. Thanks for taking a look Walter! Bend placement was mostly a result of keeping CNC-aluminum piece complexity at a minimum. By remaking the fittings straight, we avoid a more complex and larger piece which would likely drive the price on this kit up. We can easily move the bend location to our silicone hose portion of this kit. This should not function any different than the stock hoses but should certainly hold-up for quite a long time.

      Let me know if I can answer any additional questions!

      Thanks
