6.7L Cummins Larger Capacity Radiator

[Bobcat698]

Would there be any interest in a larger capacity radiator for the 6.7L?

I am going to drop mine off at my local radiator shop tomorrow to see if we can find a suitable larger core that would drop in without much issue..

Would anyone else be interested, depending on price?

I would be interested as my temps climb while towing in high heat.

I guess you would have to worry about an aftermarket intercooler or not?

I would look if i could keep my aftermarket i-cooler...

I've got an aftermarket intercooler as well. There is plenty of room between the 2 for a bigger radiator.

Will the 6.7 water pump be able to flow enough water threw a larger radiator and still dissipate the heat efficently? Maybe I'm going out on a limb

There should be no problems of any kind except for fitment of the new rad.

Lets see what you come up with.

Got some good leads so far, there seems to be plenty of room to go with a thicker actual "Core" and still be a little narrower than the actual tank width.

Take a closer look at a stock radiator and you should understand what I mean.. they aren't even taking advantage of the width they have.. it necks down almost 1/2 inch on either side from the tanks to the core!

I will keep everyone posted, I might be able to make this a production part in the end!

Ok, I have had some discussions with my Radiator shop.

While building and mass producing a larger radiator would be awesome, I'm not sure it would be feasible as the first few would probably cost in excess of $1100

However, they have deduced that the bottom THIRD of the stock radiator isn't getting utilized properly due to the location of the lower radiator hose.. if you've looked you'll see that it is 2/3rd the way down the radiator. The coolant is going to take the quickest way out so the bottom may remain somewhat stagnant compared to the flow through the upper part of the radiator.

They are going to be modifying my stock radiator to slow the water down along with re-directing the water through the bottom portion so it gets utilized more efficiently.

I will test this "mod" on my truck and if everything works out we might start an exchange program, IE have 2 or 3 radiators on hand, then take good cores on exchange.

I will keep everyone posted.

Interesting, can't wait to hear more on the results.
