Which brands of aluminum radiators do you prefer? What are the ones to stay away from? I prefer an all aluminum radiator.

I also used a universal aluminum rad, except I got mine from Summit. Like 1983SS454 stated, less than $200.00 and works great.

The Zone actually has them. Have seen some on e-bay that are $130 something to $150 something plus about $35 shipping, depending on gen. Still fighting with the shop that broke mine and replaced it with a plastic body fit all! I am supposed to be happy because I got it for free! Can you say OE? I can't, until I get that plastic thing out of there!:let_it_all_out:

Yup, they work fine. Mines a big block, using a stock shroud and clutch fan. Sits about 190 in traffic

Interesting comments. I'm not gonna need one for a while yet, but an aluminum type will help compensate for my heavier engine. The Champion brand three-row looks interesting.

Since this was brought up, I've been looking. The outfit called Ledfoot Racing has them, full sized core for my project, (width and height), 3 row, all tig welded together, and a machined billet fill neck, not a stamping. Quite impressive I think, and good satisfaction guarantee. The cap comes with it.
$219 98 and $29.95 flat rate shipping.

They claim it will cool 1000 HP.. Don't think I'll be getting anywhere near that figure!:smileyb::smileyb:

I have a small block 350 motor and want to start in the cooler weather and when I have a few bucks again to start putting chrome on the engine, etc. For this size engine, and for it to look good what aluminum radiator be best for me? Whats the purpose of a 3 row radiator, I think someone mention one? Thanks, Rango:inlove::inlove:

Most places don't say 3 row radiator, they say "3 core". Typically the more cores, the bigger the engine or performance. A lot of your stock big block radiators are at least 3 sometimes 4 core. For a mild 350 just run one of the 3 cores listed above, universals are the way I go, and just make sure you run a good shroud and fan... or if your looking for a custom cheap electric fan that works perfect is a late model Ford Taurus/mercury sable from the 90's. Its the exact size and flows plenty of air.

Do you have the part number on the one you ordered?

I need to change mine, It's got a new plastic factory replacement in it and with dual elec fans and cant keep it cool. Just got a mild 350.

If your looking for an alum Rad that is bent and formed like a factory Harrison, Have used several and ALUMATECH is by for the best copy and construction is really to notch and is heavy raw product, that is on the market if you paint it black people will not no its Aluminum. If you want to polish it like I did than they had me wait 3 extra days so they could make one that was as clean and scratchless as possible for polishing. Also its a welded not epoxy glued construction. My quote is always you get what you pay for in raw material construction IE. gauge of metal, number of tubes and size as this is were the cheating is done some of the names above use light gauge fins and smaller tubes but they do a 3 row or 4 row, but it is light weight and thinner "no life"and cooling is affected, so read the specs on all companies and or look for the good, better, best pricing.
OH ya, some bad press for one MFG I had and 2 friend had bad work bad business and epoxy failure from GRIFFIN on three orders all different and all at the same realitve time. I had the bad work on a polished order that looked like the radiator was drug through the parking lot after polishing twice and than I just asked for my money back. The other ones were real bad welds and sloppy epoxy work, the other one split open just after reaching operating temp at the epoxy seam.

This is my first post and glad to be here. I have a 1982 Elco with a 454, 700R4 tranny. I bought it in Feb this year. I live in southern Cali and the weather is picking up anywhere from 95 to 100 and noticed the car gets real hot sitting in traffic around 200 degrees. It's also boilin inside the interior. I wan to upgrade to an aluminum radiator but not sure if I should go with a 3 or 4 row? Will this help my problem? I have a heater core shut off valve already installed but it's still heats up inside. Latly one of my buddies insisted I remove the AC belt to gain more horsepower. Would this also cause my temp to rise inside the car?

Only 200 sitting in Traffic? That is fine.
It's been hot here in Texas. 100 to 105 lately.
I wish mine would only go to 200. Mine will run up to 230 sometimes. But, pretty much stays around 220. Doesn't cool down on the highway much from that either.
I have a '96 model LT1 in my 83 El Camino and am using a stock type radiator with an twin electric fan plastic shroud setup. It just has never run very cool in the heat of the summer. And now the radiator is leaking just a tad so it's time to do something anyway. That's why I'm thinking about that whole system from Ledfoot.

As far as your interior getting hot, it sounds like maybe the heater vent door is not closing. Maybe you've got a vacuum line broken or something wrong with your dash heater controls. Or, maybe some hot air is getting through the firewall somewhere.

When was this? I understand that Griffin changed ownership 3-5 years back - I've only heard good things about the new guys and the product they've put out. However, I have not heard anything specifically about a radiator for an El Camino and want to be sure before spending that kind of money.

I bought the Champion radiator today from Ledfoot.

I called them direct and bought the radiator and shroud without the fans. I talked to someone on the gbody forum that bought it and he said he liked everything except the fans. He lived near Ledfoot and just went back to the store and returned the fans and then bought Spal fans for it somewhere else. He also said his El Camino runs much cooler with this radiator versus the stock one.

I dealt with Geoff at Ledfoot on the phone and he admitted the fans they used were not the best and a lot of people buy their setup without the fans.
He said their cost on those fans is $15. So, how good can they be?

I'll get a set of Spal or Maradyne for it.

I know it's been 9 months since my last post, but just yesterday I finally had time to get my new Champion radiator and Spal fans installed.

I waited until the hot part of the day today to take it for a test drive.

WOW! What a difference. My El Camino has never run this cool. It's 98 out there and I drove it over to Sam's in stop-and-go traffic and the car never went over 185. And, wholly crap, my air conditioning is WAY colder.

I've had this car since about 1993 and went through 3 stock radiators before I got this Champion. Wished I would have had one of these all along.

Last summer, I drove it to Austin and one day was 105. I couldn't get the car to run cooler than 220 (highway or in-town). In stop-and-go it would go to 230 - 235.

Today wasn't quite that hot outside but 98 is still pretty warm. I'm guessing it will still be fine at 105.

The Spal fans are really nice too. They seem to really blow the air and run very smooth.

I'm wondering now about whether to get a Dakota Digital controller for it and set up a 3 relay system so the fans can run 2 speeds. Half speed (runs in series) and full speed (runs in parallel). I've done that on my '55 Bel Air and I really like that setup.

I've also got to get a Vintage Air Trinary switch for the A/C system. It has a fan turn-on signal when the high side pressure hits 220. I had a GM type switch for this but it doesn't work anymore.

I have a 79 that i am putting a 350 Vortec into soon, and am also looking into an aluminum radiator to put in. I have decide to go with a 3 row. I have a 4-speed tranny with AC, I'm not 100% sure if that all changes the Radiator a bunch. But I found one on eBay that's a 3 row with lifetime warranty, so they claim, and I was wondering what others who have put a Rad in would suggest.

http://cgi.ebay.com/ebaymotors/NEW-3-ROW-ALL-ALUMINUM-RADIATOR-LIFETIME-WARRANTY-/290572588450?pt=Motors_Car_Truck_Parts_Accessories&fits=Year%3A1979|Model%3AEl+Camino&hash=item43a779d5a2

The electric fans are going to be added eventually, the post about a mid 90s Tarus is a good idea, but I'm not sure if I could live with a Ford part on my GMC, so I will more than likely save up and buy the fan, or fans later.

Any thoughts, or suggestions you guys have will be appreciated.

Since you want to go electric, get the Champion with the Shroud w/o fans. Then get the dual spals. Exactly what I did.
This setup works! It's a no-brainer.

09-15-2011, 05:49 PM
I did wind up buying the Champion also, the C-161 model. It just barely fits into the space in the core support for the biggest size radiator. Hopefully it will cool OK....
A few different places on Ebay sell that brand, and I bought one from the least expensive place, Christian Radiators. Even had a few bible quote stickers on the box !

Don @ Alumnatech is a nice guy and many of the people at Team Chevelle put him up there in status close to God.

Apparently he has the best factory looking aluminum radiators out there, but hey are a bit pricey.

He also has a line of direct fit radiators that are not even close to looking stock, but will bolt right in and run for quite a bit less (I have one of these in my 66)

I think the BeCool is a bit overpriced for it's appearance, but the one in my 59 is doing the job that a stock radiator would not do.

And personally----I want my cars to run a bit hotter. 200* is nothing, but for the most part, I want it stay at close to 200 and not climb while on the hiway .

Someone at BeCool; mentioned to me that 100* over ambient should be just about right, so in 105* temps----------205 should be the norm.

I have a 65 Ranchero-----mostly stock, that stays cool enough under any condition until the outside temps reach 105-------that's when that car starts to have problems staying cool--------but it does have probably the world's smallest 2 row radiator. But, it only give me cause for concern at speeds over 70 on the freeways after about 40 miles. Slow down to 60----and all is well.

Its the 3 Row one.

What exactly are the "Spals"? I don't really know all the terminology for cooling systems.

Also, do I need to upgrade my Thermal Tepm sensor in the side of the head to put electrics fans is one day? I will adventally, but not for now.
Thanks again for the help.

Got mine from Ledfoot. I'd get it there since they have the shroud for dual 12" electric fans.

Spal is thought of as one of the highest quality electric fan manufacturers. I can get you the part number for the ones I bought if you need.

Temperature sensors that are hooked up to a gauge will not control a fan. Is your Vortec out of a newer car? Temperature sensors that connect to an ECM cannot control fans without the use of an ECM.

You need a temperature switch to control fan operation. You need to use a relay with that as well. Switches mounted in the engine cannot handle the current draw of a cooling fan. You should be able to put one in the other head.

I bought the American Eagle Rad from led foot (same company as champion). The dual 14" fans they sent are working for me so far. Most of the time they don't even need to turn on unless I'm at a stop light. Drove to work this morning with no fans and it only got up to 140 degrees (it was only 38degrees out).

I will check into the Ledfoot one, is it online or what?

Part numbers would be great seeing how I do want something that will fit in my 79 with little or no hesitation.

My Vortec heads are from a 96 truck, and I ain't putting no ECM in at all ever... I love the Carb for whatever reason, that's just me. don't get me wrong, there is nothing wrong with EFI, just I don't want it in this car. I will have a Temperature sensor for the gauge on the dash, but that's just one of the heads. I was thinking for the fan switch of getting one out of a late 80s Camaro.

What kind of set up did you use with your fans?

Thanks for all the info, and help by the way.

If you go on Ebay, you will see that the same part number radiator (champion) is sold by a few suppliers, so you can shop around a bit for the best price.....

One way is an Ebay search for 1979 El Camino parts, which will turn up radiators and lots of other "stuff"..

Looks like your other questions were answered. Note that Ledfoot says the shroud is optional. Be sure to get that. It fits well and you will need it to mount your two 12" fans.

Here's a link to a temperature switch similar to the one I have. It has a 190 deg on and a 180 off that I think is a good. Be sure to run it with a 180 thermostat and not a 195.

http://www.summitracing.com/parts/HFM-ZFSWF/?rtype=10

I like these relays. They come with a nice socket and pig tail. They are what I buy. You only need one.

http://www.summitracing.com/parts/DAK-RLY-1/

Does you car have A/C? More to talk about here if it does. A/C condensers can need the fans to come on too. And the engine may not be hot enough to turn them on when the A/C needs them on.

There are other setups for 2-speed (half and full) fan operation you can do. I didn't do this in my El Camino. But I did do it for my '55 Chevy Bel Air that has dual 14" fans.
I used a Dakota Digital fan controller and 3 relay for two speed operation. The Dakota Controller also has an input for an A/C switch so the controller can turn the fans on when the A/C condenser needs air flow.

Two-speed fan operation can also be done with 2 different temperature switches and 3 relays. But I like the flexibility the Dakota Digital controller gives you.

I have schematics for these 2-speed setups if anyone is interested.

Thanks for finding those parts... I'm gonna get them as soon as I order my Radiator and stuff.

My car does have AC... Which is why for now I am going to run the stock exhaust manifollds for a while. We will probably need to talk more about the relays ans everything for the AC later when I get the car up and running, which will hopefully be in a few weeks, but does the Dakota Digital controller tie into the relays for theTemp fan control? It sounds like it from what you said, but I just thought I'd ask and see.

Looks like the one. I didn't know they fit a Camaro too. If you don't like the fans, you can always get the Spal fans down the road.

I got mine without the fans because I guy I talked to didn't like them, returned them and then bought the Spal fans. He loved the radiator though as do I.

When I was looking for my fan controller I spoke to the guys at my local speed shop. They only had 2 to choose from but they were both Derale (single stage or adjustable). I bought this one
http://www.summitracing.com/parts/DER-16738/
I know you have more demanding temperatures than I do but they told me that they only typically need to run 1 unit. Everyone else has told me 2 but I listened to them and installed the only 1. The instructions in the box were very clear on which wire goes were. Took me about 2 hours to install the shroud fans and wiring.

There is a dedicated A/C / Switch override line which ties in were the thermostat line comes into the relay. Overall the unit was well laid out and I haven't blown the fuse yet.

Here's the fan on the Spal site:

I paid $125 a piece for mine.

I just found one on ebay right now for a super price:

I'm running the Alumatech radiator with the Spal dual fan set-up.
So far it holds the temp to just about what the thermostat is designed for. About a 5 degree variance is about it.

The Spal set-up is programmable and also has the capability to go to full speed on both fans when you turn on the A/C.

I used my existing shroud and cut slots to accomodate the footprint of the dual Spal assembly.

You wouldn't know it was anything other then a stock set-up unless you noticed there was no fan hanging off the engine and got to looking a little closer.

awesome! thanks for the help.
How does the mounting of the fans work exactly? I just don't want to mess up my Radiator by putting the tie deals through in between the fins on the radiator.

What would be the best way to mount these up?
I raelly want to use the sock fan shroud just cause it would look more stock that way, even if I have to modify it a little bit.

I mounted mine on the shroud that came with my Champion radiator. I'll never use those ties that go through the radiator ever again.

I cut the top part off of my original shroud and it holds the top of the radiator in place.

Thanks roger, thats pretty much what I figured about those straps.
How did the shroud mount up to the radiator? I'm trying to figure out a way to mount the shroud that came with the radiator.
Would it be possible for you to take some pictures of your set up?
I would really appriciate the help. I want everything on my car to be done right, and not jimmy rigged up, also i want it to function the right way, obviously.

Thanks again for the help.

Sorry, I don't have a picture.

Deal with Ledfoot on this. Their shroud bolts to the radiator and the fans bolt to the shroud. It's an excellent set up.

Ok, New Radiator installed, I will get pics soon, I was wondering how I wire up the dual fans to kick on at a certain temp.

I know I need a temp switch thing in the side of the head, do I also need to wire up a relay?

does anyone have a diagram of what they did for thier wiring or at least know of a place I can find a diagram for wiring in dual fans?

Thanks guys

You will need a relay----or two if dual fans

If you have AC---might want to get a trinary switch.
Or you could use another relay to trigger a ground circuit using the AC compressor to power the relay.

Awesome,

Thank you all for the help with this. I got them wired up tonight, the motor didn't heat up enough to trigger the relay, but we did just touch the wire to the swicth to a ground and they kicked on.

I do have a question about my Temp gauge sending unit.
On my 305, it worked just fine, no issues.
The thread on the original is 1/2", and my new haeds are 3/8" thread.
I bought a new one that fit in the new head from a local parts plus store, but it won't work.
My question is, has anyone had an issue with the temp gauge not working, and how could I fix it?
We took the old one and jooked it up to the wire, held it with plyers, and heated it up with a torch, no go.

Anyhelp would be greatly appreciated.

The sending unit makes ground through the threads. The new one must have the same resistance range as the original.

How can I find out what resistance thesending unit has?
Is there a list out there of what it's supposed to be at, or do I need to just test it?

I have seen it posted on here at some point but don't remember. Maybe someone will jump in that has the info. A REAL parts house can look it up as well.
