Any one tried one of these? my rad is leaking out the end tank and need a new rad. https://afepower.com/afe-power-46-52061-bladerunner-street-series-radiator#overview It sure looks nice and its thicker then factory but its a 3-row. Ive read that 3 and 4 row rads aren't necessarily better in aluminum as was with copper and brass. https://www.dewitts.com/blogs/news/14141757-are-three-row-aluminum-radiators-better-than-two https://www.speedcooling.com/blog/category/radiators/3-row

I wonder what tube size afe used . id love to have a all aluminum rad with out those crappy leaking plastic end tanks but then again, not sure... I know about the Griffin rad but don't want to spend that much right now. So whats y'all thoughts?

Yeah I saw that thread, but the afe rad wasn’t really talked about much . But based on my research. It sounds like a 2 row aluminum rad is better then a 3 or 4 . Since the tubes are bigger you get more surface area. I can’t find any info on what tube size afe rad is . Unfortunately as of right now I’ll probably be looking at other options.

If leaking where end tank attaches, that is an easy fix.
steve05ram360 did that repair with great success, send him PM or locate the thread.

This is the thread...

https://www.cumminsforum.com/forum/3rd-gen-powertrain/2141234-radiator-repair.html

It did clog up on me about a year ago (13~14 months), cleared it and still working as expected with no leaks. I do run a 7 psi cap though and do not tow. OP that link might be a good temporary solution until you decide what rad to get.

That AFE looks to be a nice piece, I am going to need to build a new shroud for the volvo fans and am considering that radiator as a replacement for the stocker. Fitting it is going to be the question to answer for me, I have about an inch off the fans to the crank pulley. So not much room for anything too much thicker.


AFE is on sale here... $425 with free shipping.

You still want the afe even though its a 3 row? from what I read the 3 and 4 row aluminum rads aren't as good as two row. they have less surface area cause the tubes are smaller. from what Ive been about to find on the Oem uses one inch or 3/4 wide tubes in the core . I'm not sure what afe uses haven't been able to fine that info yet. probably will have to call or email them and ask. I suppose even if the afe has smaller tubes it might make up for it with the 3rd row. But if the tubes aren't not much wider then oem it might equal out to be the same as oem...... Me brain hurts :| And yeah I haul and tow with the truck as much as 21k gross .

Its leaking out the buttom at the end tank. I tried to take pliers and re crimp it best I could , It slowed it down but its still leaking . might also be a hair line crack I over looked to.

in order to determine how much surface area is available to the coolant you would need to know the inside diameter of each row. if for example, both setups used the same core row size its clear the 3 row has more surface area. then if really wanting to analyze it, whats the difference in row contact to the fins to shed the heat? one of the issues with a non staggered core setup is the 2 back rows do not get the benefit of the frontal airflow since they are blocked by the tube in front if it. a staggered setup would he the way to go. off the shelf setups are not going to have a stagered core setup, too expensive. the guy i chatted with to fix that btr educated me on it and stated the best setup was going to be a brass stagered core setup. $1100.

i think even a smaller diameter stagered core setup will perform well cause of the coolant contact and the fans ability to shed the heat from the core.

that afe is still newish to the market, read only one review of it and the guy broke the overflow nipple during the install. a call to them with concerns may be cleared up with an update to the design. if i had the need for a rad, i would do it and solve any problems that came up. but, like i said, oem continues to serve leak free, still the original one from the factory... and no heating issues that i dont create by covering up the front... (runs hot on one grade coming home, 208* vs the normal 199-201, this is with no fans turning on.)

RE: cooling ..your 21k that you tow, would love to have a buddy close by who wanted efans, i would definitely help to get it dialed in under the worst conditions. one if the thoughts i had was to add an additional cooler to the cross over pipe behind the head, or easier yet, where the trans heat exchanger is. pulling heat out of that line or the return line from the heater core would work to stabilize engine temps better.

i would bet Rwright07s setup would have worked better with it and he may have stuck with it vs going back to fan clutch setup... (he was up over 26-27k iirc)

I’m on the east coast, In West Virginia probably to far away I’m sure to far to experiment with efans

You make some interesting points . I’m assuming you saw the two websites I posted links to in my first post explaining why a two row aluminum rad has better cooling then a 3 or 4 row aluminum rad ? I know it’s all just options but it would seem like it’s plausible.... at lest to my red neck brain that is

I agree that you do reach a point that a thicker core has minimal cooling gains due to reduced airflow.



Other than the AFE and Griffin rads, I don't know of any other heavy duty rads for the 3rd Gens.
If you know or find any other options please let us know..


My stock rad core thickness is just under 1.5" thick.

The Mishimoto 3rd gen rad is 1.34" (approx 1 3/8") thick.

The OSC stock replacement rad is stated to be 1 5/8" thick.

AFE 2.0" thick.

Griffin 2.68" thick.

I’m sure the afe is a good rad . I’m not arguing that. What I’m wondering is if since it is a 3 row and oem is 2 the oem cooling tubes might be wider then the afe . If that’s the case the afe might not cool much better then a oem . From what I be able to find on line . The us standard for performance aluminum rad is one inch wide cooling tubes . So that’s two inches of surface area. Imported 3 row aluminum rads are 16mm or 0.62 of a inch . So that’s only 1.86 inches of surface area . Base on that it would seem a two row aluminum rad would be better for cooling . How much of difference would that really make ? No idea... but I’ve also read that when you have more rows it slows the air down trying to get through the rad . Probably way over thinking this but I do what to get what I pay for .

I have found two aluminum rads on eBay... yes yes I know they probably are Chinese. But I bet most if not all rads coming in new vehicles are Chinese anyways. But what I liked about them is they are a two row and unlike the mishimoto rad the core is the same thickness as the oem. It says up to 30% better cooling but I don’t really buy that. What I do like is that the end tanks are aluminum. And assuming they are welded right they should out last the crappy plastic end tanks . Don’t expect them to perform like the Griffin, but for the price it is tempting. Could hold me over until I can get a griffin .

Those Chinese Ebay rads do not appeal to me at all but it is certainly possible the AFE rad is made in China also.

The Ebay rads state to be 1 5/8" core thickness. About a 1/4" thicker than stock but a long ways from the 2.0" thick AFE.

I would bet the aluminum in those Ebay rads is paper thin, similar to Ebay/Chinese stainless steel headers and exhaust systems.

The radiator discussion is interesting. I hope I'm not the 1st one to try the AFE 3rd Gen rad. :)


Updated:

Stock rad core thickness is 1 7/16" thick.

The OSC stock replacement rad is stated to be 1 5/8" thick.

AFE 2.0" thick.

Griffin 2.68" thick.

Ebay/offshore aluminum rad 1 5/8" thick.

I’m sure unfortunately the afe is using Chinese aluminum. I know the mishimoto does. The afe is thicker then oem but it might have smaller cooling tubes since it’s a 3 row . I’m going to email afe and see if they will tell me the size of the tubes they used .

Do it :grin2: someone has to be the first here... I may be forced to do it when the next e-fan shroud project gets under way... but thats still a ways off.

The OSC also has plastic tanks... I'm sure plastic tanks are fine... but I'm more old skool - I want metal... but for your OEM rad repair, you know they are just glued on, right? (for extra cooling, you could always just stick a big heater core under the truck with a little 12v fan behind it... I did something like that in an old plow rig I drove, but put it inside.)

looks like the Osc is a rebranded spectra premium rad . Thats what I have in my truck now, I had it since 2013. Napa and auto zone sells the same thing. Its interesting that OCS and spectra premium list slightly different dimensions AftermarketData.com | Automotive Parts Management, ACES PIES Mapping https://ecat.spectrapremium.com/products/CU2711 , But when I replaced the oem rad back in 2013 I set both side buy side and in front of each other. they were the same size, only difference I could see. Is the nipple right at the filler neck for the over-flow hose was smooth on the spectra premium and oem had two barbs molded on it. Btw Im still waiting On afe to reply to my email....

Well this is interesting info...

Per Mishimoto, their Tank Wall Thickness is 0.08"

Per afe, theirs is 1/8" which is 0.125"

Afe finally answered me . He didn’t know the tube size they used but said they were a little bigger then factory he was told . He also said some of there rads come from China and some are built in house . He wasn’t sure if the one for the 3gen was made in house or China . Sigh not sure what to do. I’d like to know for sure what the tube size is . But I’m probably not going to find that info .... and the sale ends in 5 hours..... decisions decisions.
