Re: LS swap radiator, other than entropy and R&D
I guess most of the more recent engines I have seen have been on cars, water pump may be set up differently. The radiator is sealed with a filler neck going to the top of the water pump. That's where the breather line to the surge tank is too.
If you have air stuck in your rad you have to burp it out by squeezing your upper rad hose. |

System gets filled from the res tank if your running one, otherwise right into the radiator on plenty of swap trucks. I saw Ryans truck in person, and the amount of trimming to fit his new rad is actually really small. Its just about the 3/8" lip on the backside of the core support, so it sits flush and has something to mount to.

Re: LS swap radiator, other than entropy and R&D
Ls car motors fill from the overflow tank.

Re: LS swap radiator, other than entropy and R&D
what OEM-style radiator that has been produced in the past 60 years can't support 2 fans in a shroud or a tranny cooler?

Plenty of vehicles don't have fluid passages for a trans cooler. Some was an option, others were HD use only...and plenty had M/T. If you want to run without a dedicated trans cooler, you'll want a place for it in the rad. The AD and earlier rad's would be too small for most of the cheaper large diameter electric fans, so to run 2 fans, your going to the smaller units (they still work, but not everyone wants to spend the extra $ for that, just to retain an old rad style, if they have to buy a radiator anyway. ) I'll be vain and add that copper is kinda ugly under the hood if the style doesn't fit the look of the truck/engine. Aluminum is also strong, light, and easy to repair (more guys know a TIG welder than they do guys with brazing skills)

now, if you want to talk weight savings (since thats what spawned the advent of aluminum radiators in the motorsports circles) then you have a valid argument. Quote:

anywhoo, i notice a trend in this thread: the only guys that are pro-cheap chinese aluminum radiators are the guys who have already bought them. |

Re: LS swap radiator, other than entropy and R&D
Cheap yes, but over 3 years in use 2 power tour over 3500 miles each in 7 days and not one problem. The copper is fine if that's what you want. But todays world the aluminum will cool better per the way they are designed.
Yes I have already bought mine but I also had my truck 31 years and ran the lesser copper one for the most part of those years in fact I have 2 of them in my building that I took out because they are crap the last one had plastic tanks lasted about 3 years of everyday driving. Cheap crap is out there no matter where it's made. I'm just stating facts about mine. Ugly under the hood is opinions as said above. I like the aluminum one I have. It works great it was cheap enough and everyone likes a good product for a good price and that's what I have. There is no doubt there are cheap ones out there but do your home work before you buy.

Andy, be careful running at temps lower than stock. You want your engine to get hot enough to boil off condensation and other water/stuff that's gotten into the oil.

Re: LS swap radiator, other than entropy and R&D
Just ordered this for my 69.
https://www.summitracing.com/parts/gri-8-70013-ls We'll see how it goes. Also, for what its worth: While copper is more conductive that aluminum, no doubt about that, the soldered joints between the copper fins and tubes are much less conductive than the welded connection between the aluminum fins and tubes. |

https://www.amazon.com/APDI-Radiator...s=APDI+8010284 It'll cool an "LS" engine just fine and it'll bolt right in. It'll also save you a few bucks to spend elsewhere as these swaps are expensive enough already. If you prefer the looks or performance of a particular custom radiator, by all means, buy it. But it's not "necessary". |

Re: LS swap radiator, other than entropy and R&D
I just installed a radiator in my '51 made by Superior Radiator. It fits great and I will be buying from them again for my '64 Suburban

Re: LS swap radiator, other than entropy and R&D
I'd avoid the Griffin. Mine literally started separating after a little over two years. Looking at the Be Cool Bone Yard Series or Northern but for now I'm running the old Speedway or Summit aluminum radiator from my smallblock.

Re: LS swap radiator, other than entropy and R&D
I’ve got 4 years and over 10,000 miles on my speedway radiator here in Texas where I drive it all the time. This is for my LS swapped truck and I have no issues. I am building a LS swapped K5 right now and will be putting in a similar radiator for it. You really can’t beat the speedway/summit/jegs branded radiators for the price and quality.
