Cooling the Cummins- Nissan Titan XD Aluminum Radiator

Part 1: Stock Evaluation

Since Mishimoto’s inception, we have grown to become more than just a radiator manufacturer; have expanded to offer many other performance parts for a variety of applications. For the Titan alone we already offer a several products, including an intercooler pipe and boot kit, exhaust, and coolant filtration kit. We have not, however, forgotten our roots. That being said, we have begun developing a radiator for our Nissan Titan XD.

What improvements will we make?

The stock radiator is sizeable compared to other stock units we have seen, but we still found some areas where we can improve on the factory design.


Stock Titan XD radiator

We plan to increase the core thickness and create a fully aluminum radiator, including the end tanks, for added durability. The factory radiator utilizes a detachable, plastic fill neck, which we will include with our radiator, but ours will be constructed out of aluminum to eliminate another potential failure point.

Prototype

Thanks to our rapid prototyping techniques (and talented engineers), just a few measurements can be turned into an intricate 3D print.

We 3D print our prototypes first to ensure a great fitment before we create an aluminum prototype for testing. This process allows us to test fit the radiator and make the small changes and tweaks to our design before we finalize it. This makes for excellent fitting prototypes and production parts, often on the first try!


Prototype radiator for test fitment

With the stock radiator and intercooler removed, you can see how much space we have to work with in the Titan’s engine bay.

We really reached into our creative side when printing these end tanks. Purple and orange create an interesting contrast to the Titan’s black-clad engine bay (but maybe we are just partial to orange 🙂 ).

We have noted some slight tweaks that need to be made for a perfect fit, but once they are added we will be ready to kick our radiator to the next level.

Next Time

Now that we are sure of fitment, we will create an aluminum prototype for additional testing. Let us know what you think of the project so far, and stay tuned for photos of our completed prototype.

Thanks for reading!

Not going to run out and buy one, but when the stock end caps start leaking in a few years it'll be nice to have a better than stock one available.

Does the transmission cooler also run through the radiator?
This can be a problem on the older Titan and the reason I ask.

Thanks for the kind words! You are correct, the stock radiators being so new, there will likely not be many failures until the plastic radiators begin aging. We wanted to create an option for those who will be using their truck for performance or towing and want the added protection of a fully aluminum radiator.

Great question! Yes, there are fittings in our radiator to accommodate the stock transmission cooler lines.

As soon as i looked at the Titan engine I knew that the plastic parts on the radiator would be a weak link. When mine wears out or disintegrates, I'll be happy to buy an all aluminum radiator.

Aside from replacing plastic, what is the improvement over the stock radiator? Better capacity? Better flow?

Will any any horsepower adding stickers be accompanying this radiator?

We look forward to helping you with that in the future

I'll talk to the engineering team and try to get you those stats for you!

Our stickers are more about torque and 60-ft times, not a whole lot of power to be had with them

Thanks!
