A special thanks to @schiker for saving me shipping cost and helping with delivery by meeting my wife and getting 2 large radiators into a small car safely..

We went down to the Griffin plant 2 weeks ago and I ordered this radiator. I wanted a 1/4" bung above the bottom hose so I can install a temp sensor matching the motor sensor, plan is to wire a toggle switch so the gauge will read either sensor. I wanted to be able to monitor the water temp entering the motor at various times.

This unit uses two 1-1/4" rows, Griffin says around 15-20% more capacity than a stock 4 row radiator. I will be checking this with my stock brass unit, I will plug all the holes and fill both up and see what the difference is between the two..

Hopefully this weekend I will get this all prepped and sprayed with a thermal dispersant...

If anyone wants a top quality radiator that is really made in the USA this is a nice unit.. not cheap but well worth it for hand built & welded....

Way cool! Yes, pun intended.

Being Aluminum we know the coating is going to to increase cooling by 33%. Then the design being bigger than a 4 core... wow.

Many people invest big $ in one of the big radiator mfrs. like Griffin (a great name in racing radiators) and leave it unpainted. Then don't understand a few years down the road why it doesn't run quit as good as it used to. The aluminum starts getting the aluminum-oxide coating on it and it cant work as well. I feel really bad for the people in salty-air because along with their steel rusting, aluminum oxides much faster when untreated, especially when in contact with a dissimilar metal like bronze or steel.
In fact, 30 W/m.k is all, vs 237. The tests I found on the TLTD painted Al showed 309.

All this being considered, you should figure a cost of doing this to a radiator for others, and anyone that can afford treating their radiator either aluminum or copper/brass needs to seriously consider it.

I have mentioned my plans on doing my Hummer radiator (desire entire stack actually). I just wish I could do the proper thermal testing before and after to show it in math like has been done on aluminum radiators and innercoolers. If anyone knows proper testing procedures, lmk.

Waiting patiently for pics or videos on doing it/ finished product.

Yea it will last forever and will perform well..

I'm building my last truck, so I don't mind paying for what I want and spending a little now knowing it will out last me and still perform as designed...

I do have a cost listed, I do some for local's now...

And with a NEW product from Techline radiators with plastic ends can now be done and no need for oven curing....
 
Interesting to know IF after the OEM airflow problem is solved we can actually use the bigger radiator.
 
I do have foam rubber I will be placing between the radiator and the support to force all the air to pass through the fin area, that's about all I can do in that area. While I have things apart.. I'm changing the lights to the quad style... I'm toying with the idea of building a funnel type deflector between the grill & support to see if I could get better flow through the stack...

The cool thing about the coating is the efficiency is there regardless of sizing or flow, it is just sheds the heat 1/3 faster. The arrangement/ better designed aluminum radiators can flow air better than the older cramped gm radiators.
 
If it is an aluminum cooler for your transmission, simply imagine a transmission cooler that is 1/3 larger in size. The copper, brass, or mixed metal coolers I haven't found any testing that was done. But people that have coated both kinds of radiators say as one guy put it "about the same level of amazing".

Doing the transmission (or oil pans and valve covers on engine) helps alot, as they are designed to help shed a bit of heat also. Dodge actually did an off-road set of pans that were fairly thick to resist puncture, and found it increased heating issues in hot climates. They quickly abandon that concept. GM reportedly had it on the drawing board at the time and ditched it for the factory skid plates.

How do you suppose the coating would work on the transmission?

To simplify the answer, the product is a "Thermal Dispersant" there are people that have coated entire motors inside & outside. Nascar use to allow teams to apply this very stuff to an array of parts from front to back of the cars, this product is so good at doing it's job that it is now outlawed in all of Nascar divisions... Nascar didn't like all the bumper-bumper racing, this coating allowed that with no over heating problems, teams could stay locked all race long, the effects of the coatings would allow for cooling so good that people & Nascar wanted them NOT to be bumper-bumper... without the coatings they will overheat...

Now the NHRA is a different story, they don't baby their teams, this and many other products are allowed and widely used, most of Techlines products were developed with & for the NHRA and they are still coming up with more good products..

Your short answer is yes, it will help remove heat....

How much?
 
Getting close to hummer pricing. Then again, Hummer "factory" radiators are hand built on a jig by the best copper radiator mfr in the country. Griffin and Ron Davis are the 2 top in aluminum, but you sure have to pay for it. High ambient temps and high performance makes for a pricey combo, but better to pay a bit more upfront than a lot more down the road.

I think most would do fine the the Mishimoto form Leroy for the gmt400s.
