LS swap radiator, other than entropy and R&D
 

SO after alot of forum searching, it seems like people argue over entropy and r&d. Does any one have experience ordering an ls radiator from summit,jegs, speedway and mocking it up them selves? Other than a plastic radiator from the boneyard? I feel like we could save a few bucks doing it this way. I found a few radiators that seem like they fit, but I never had a stock radiator to get measurements from.

I got my rad from Sparkey R&D the quality looks to be good and I have had no problems with cooling "the engine"

. I didn't do my home work and missed that on his ls swap rads the outlets are moved to the passengers side. That made for a nightmare finding hoses that fit. He was no help making suggestions on what could work. In the end 1996 jeep grand Cherokee 4.0 hoses fit great.

He did tell me the transmission cooler was moved to the drivers side. That's fine. That makes running the transmission lines a little more difficult. I got over it and the problems mounting the fan shroud.

I was very specific when I ordered it that I wanted to use the factory fan shroud and did not want to modify mounts to make it fit. Well it turns out if you have 3 core mounts the fan shroud will not fit. You need 4 Core mounts

Here is a picture of my transmission temperature without a external cooler also look at the intake air temperature to have a Idea how hot it was out side. I ended up bypassing the rad trans cooler and went with a B&M super cooler and fan kit. I have a ton of money into my 4l80E and cant risk 220+ temperatures empty cursing the hwy.

I used a stock radiator from 02 camaro, it fits good. I had to drill new holes to use top mounts. But the hose locations, trans fittings, and air bleed hole for heads is where you need them.

I'm using an aluminum unit from "speed daddy" on eBay. Comes with trans cooler hookups, bolted up to rad support using stock mounts. Even came with 2 electric fans although I'm still using the lq4 clutch fan. Seems to work fine. For $160 and free shipping it was worth a try and so far so good

stock 4 core.

cools fine with an AC condenser and a water-to-air intercooler heat exchanger in front of it.

I used a Summit dual pass radiator with a 16" Spal fan on a couple of applications and they cool very nicely. External trans cooler.

The dual pass has the inlet and outlet on the passenger side for easy hose hook up.

I used a Spectra cu730 (454 radiator) in my 76. Bought the 454 bushings and a factory 454 top plate. No issues and great fitment.

Re: LS swap radiator, other than entropy and R&D
 

I'm using a Holley frostbite in my 72. It's working great so far.

Re: LS swap radiator, other than entropy and R&D
 

Used a Speedway generic radiator on mine and ran external coolers for the trans and oil.

Re: LS swap radiator, other than entropy and R&D
 

I used an engineered cooling products rad that was built for our trucks and the fitment was perfect. It also came with duel electric fans. So far so good haven't really driven the truck in hot weather yet so I can't really give a total review but for now its been great, no issues.

In my '62 5.3/4L60E I used a champion off eBay...make sure the spouts are welded and not pressed on..worked fine for me..

Re: LS swap radiator, other than entropy and R&D
 

You can go ROCKAUTO.COM to get specs on any radiator you want. I used a stock radiator for a 96 C1500 v6 pick up perfect fit, proper hose sizes for the LS.

Champion and American Eagle!

Re: LS swap radiator, other than entropy and R&D
 

I need to order one ASAP. Any other suggestions? I'd love to run a crossflow but I don't think they will fit using the stock battery box location? This is a 400HP LS1 with Vintage Air and a 4l80E

eBay http://www.ebay.com/itm/351599620760

This is the one I bought and it fits well. I haven't run it yet but I don't forsee any issue with it.

Re: LS swap radiator, other than entropy and R&D
 

Because I'm running a 2010 vette motor I elected to get a 2010 vette radiator and fans but the radiator doesn't have a fill port on it so I looked at dimensions of the 2011 and 2012 vette and camaro radiators. The stock 2011 camaro radiator uses the same hoses as the vette so I bought all new hoses, cap, radiator, and fan assembly for a 2011 camaro and it will all work. I will have to cut up my core support but that doesn't bother me. But it saved me a lot. Entropy was around 850 shipped and rnd wasn't far off. I paid 440 shipped for all new stuff from rock auto, the other cool thing as previously stated was you can see what sizes they are before you buy them

Re: LS swap radiator, other than entropy and R&D
 

I picked up a Northern radiator last year when I had the inline 6. It was cheap, not a direct fit for my 66 but it fit well, and is compatible with the LS swap I'm working on right now. Neat thing about their radiators is that they sell an electric fan setup for each one they make. My buddy has run Northern radiators in 3 of his last 4 projects with no issues.

It's P/N 209676 for anyone that is interested.

New engines should fill from the cap on top of the water pump right?

Re: LS swap radiator, other than entropy and R&D
 

Cap on top of water pump?..I've never seen that..got a 2011 ls3, a 2013 5.3 and neither have a cap on water pump...

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.

Ls car motors fill from the overflow tank.

Re: LS swap radiator, other than entropy and R&D
 

....Where exactly does this cap exist?

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
 

Is this the rad, and were the hose sizes matched to the LS water pump?

Thinking about this aluminum version... http://www.ebay.com/itm/3ROW-CORE-AL...BY3xa4&vxp=mtr

Re: LS swap radiator, other than entropy and R&D
 

Been reading good things on champion...

Re: LS swap radiator, other than entropy and R&D
 

Exactly what I used. Had Rad shop change upper hose diameter and add steam port. Works perfect. No need to get exotic
