Radiator search
I've looked at every forum I could find about radiators and now I'm just more confused. There are no current posts I could find on what is not having leaking issues after a short time. It kills me to pay $1500+ for a radiator that has a good chance of having problems. What have you currently bought and used that you have had good luck with ? Going in a 72 C10 with a LM7 and a Tremec magnum. I in Fla and will run air so I need something that will handle the heat.
Thanks, Bud |
Re: Radiator search
I have a Cold Case radiator that is a dual pass. Both the upper and lower hose barbs are on the RH side and is designed for an LS conversion. It will handle 100 degree temps with the A/C blowing and a trans cooler mounted out front.

I used a DeWitts LSX Modified Radiator
Made in the USA with a Guarantee. I used the same company for my Corvette. I haven't heard of a single complaint from this company. The LS bare finished radiator is $900. It doesn't come with any fans. https://www.summitracing.com/parts/dwr-3139018a The ice black version with fans is $1600. I paid $1200 a little over a year ago. I previously purchased a China radiator before going full tilt. It was advertised for our trucks and didn't even fit the factory bracket locations. The shroud was too close to the radiator as to make much of the surface are ineffective. The Dewitt even has flaps that open when you are at speed to keep the need for the fans down. Lots of options. Even some keep the stock radiators and use the long cross over hose like on the trucks. The bleeder hose from the heads and be added to any hose using the adapter found on eBay. Picture attached. I found the inexpensive radiators a frustration I didn't need. Do what is best for your budget and frustration tolerance. I found it only hurts once if quality is purchased. Cheers. |
Re: Radiator search
I have this one in my C10 and it’s been great. I’ve had it for a few years and zero problems.

Re: Radiator search
$1500 for a radiator? More money than smarts.

Re: Radiator search
I have the 2-row Cold Case. It bolted right in where my old 4-row brass GM radiator went.

Re: Radiator search
I rebuilt and converted my brass radiator to a four core; for my LS conversion.

I can comment about what I have used. Four Seasons, made in USA, is in one of my modified cars (383 Gen 2 LT1/T56) and has worked perfectly for several years. I also have a Cold Case in my 67 Camaro. It is made offshore as the $ would reflect but does have a lifetime guarantee. IDK if they make anything for custom builds like a LSX in a C10 so US company like Four Season or DeWitts one post notes would be the direction to head or find something from a modern car/truck that uses the engine you have and see it it can be mounted efficiently in the C10. Junk yard with fans?? I assume it will be a "coolant recovery" type (external tank fill) radiator. Don't cheap out on fans You want a radiator with fewer, larger, rows vs one with more smaller rows. 2-3 row 1 1/2" tube |

Re: Radiator search
I appreciate the responses. I've looked at all that were mentioned and most of late are having problems with leaks for some reason. I can't see myself spending almost $1800 with shipping/tax for a freaking radiator. If I get aluminum it has to have a lifetime warranty for that money..... I found Engineered Cooling Products and it $750 plus ship/tax, anyone have experience with them ?

Re: Radiator search
I bought a $143 radiator off of ebay, back in March. Took a 100 mile trip Saturday in 105 degree weather with A/C running the entire time. Cooled just fine.
PS> I am running a mechanical fan w/fan clutch. 6.0 LS with 4L80E. |

Re: Radiator search
Engineered Cooling Products yes, that's what I have but I don't know about the $750 one, I just have the one that's $297 for a stock setup. I guess you're needing something special that matches the engine. I do like the lifetime warranty, we'll see how that pans out.

Re: Radiator search
When I was looking, I called a few custom radiator manufacturers. The prices varied greatly, but one thing I was told was that the cores were all coming from China. The tanks were made in USA and welded on the core, but there is/was a core shortage and getting a radiator would take a while.
I am not sure which company actually makes a core in the USA, but before you drop serious cash on a supposed American radiator, you might want to ask. |
Re: Radiator search
Are RnD Fabrication radiators in the mix anymore for C10s?

Re: Radiator search
I bought this:
https://www.ebay.com/itm/352233489480 I don't regret it YET. I did change out the chromed fans for a pair of SPAL fans. |
Re: Radiator search
I've had a engineering cooling products radiator in my Camaro for 6yrs now with no problems. It solved my heating issues in slow traffic. Bought one for my 72 K10 also.

Re: Radiator search
Looking at recent reviews of these big dollar radiators isn't good. I'm putting some money in this truck but a $1800 radiator isn't going to be in that stack. I think if I could find a decent radiator with both hose ends on the passenger side (I hate the coolant hose running across the front of the engine) I'm going to try that. I'll get a good set of fans/shroud and see how it flies. I'm building this truck from the frame up so changing a radiator is in my wheelhouse.... Thanks again..
