Dear All: I Need to replace my Toro 67 radiator and I am looking first for a good OEM replacement, since I live very far away my room for error is minimum! (Buenos Aires), so help is appreciated for guidance on source and type. Also i understand the original is 3 core, is a 4 core good idea?, waht about OEM vs. aluminum?, Best Regards. Raul.

Raul, do you currently have a radiator that leaks? If so, I'd say you should track down a shop in Beunos Aires that re-cores radiators.

Olds64: yes, it leaks and badly, so it needs to be re-cored, as you should have imagined I have almost exhausted local options here, It is possible there may be still someone here who can re-core this old radiators but I will trust that search to local forums here, on the other hand being so far away it is always good to have a spare radiator specially since I have another 425!, so now back to my original question: any chance to have some advice there?. Best. Raul.

Are you familiar with the embossed two letter codes on the back of the Harrison radiator tanks and the radiator tag itself, if still present? You may want to post pictures of those.

Gauchobyte

Not familiar, will take a look, but.. my two olds the Toronado 67 and Delta 88 66 have exactly the same radiator, 3 rows exactly like this

I will take that bet. I would agree that what you have has the same general shape. Core dimensions , hook up diameters, and particularly the passenger side tank can vary quite a bit. The drivers side tank is often an IA code.


I have a stash of original radiators in storage that I removed from junk yards years ago. But most used radiators likely need a new core.

I believe the 1968 Toronado radiator is wider than the one used on the 1968 Delta 88. I'm not sure about the 1967 but believe you shouldn't trust the Summit interchange but find out what the Oldsmobile reference says about interchange. Can you take some measurements in inches of the radiator you have and share with us so we can help verify what else has that size? Also check the tank sizes as I believe the drivers side tank is larger than the passengerside.

will do and revert. Tx.

Check out U.S. Radiator, I used them for a replacement on my 63 Starfire.

I can only measure my radiator with the upper supports on, so here are my findings FWIW: Width 35", Height 18". Driver side Tank 1", Passenger side Tank 3.5". Needless to say measures are aproximate.

Now, Looking at the Oldsmobile Parts and Accesories 1972 this is the best I got

66-67 Tor exc. C.A.C or H.D. cool #3006143 (Toronado without Comfortron or HyDramatic(?) Cooling)
66-67 Tor C.A.C exc H.D. cool #3005243 (Toronado with Comfortron and without HyDramatic(?) Cooling)
66-67 Tor H.D. cool #3005247 (Toronado with HyDramatic(?) Cooling)

My Delta 88 on the other hand..

I was also looking at the suggestion of US radiator and they look really good but sustantially more expensive around u$s1000 vs. u$s360. is it woth the difference?

Best regards

H.D. = Heavy Duty

Gauchobyte

Thanks Tri-Carb!, I suspected I was on worong on this. Now for closure then

66-67 Tor C.A.C exc H.D. cool #3005243
66 5200,5400, 5600, 5800, 98 C.A.C. W/H.D. cool exc. A.I.R. #3005748

So they are not identical as I declared, altough they fit between.
Heavy Duty Cooling I would asume is 4rows correct?

Raul—during the 60s the Harrison radiators, the GM brand, made 2,3 and 4 core radiators. In general, the smaller the engine without AC, the smaller the number of cores and/or tanks. In contrast, the bigger and heavier cars with AC would get bigger tanks and 4 cores.

Does your current radiator have 4 cores? If your copper tanks are good, you can measure for a replacement and have a pro with a torch and a solder sucker remove and transplant your tanks to the replacement core. Be careful about who you use because the tanks are easy to bend and ding.

If your current radiator has the factory tag still on the back of the passenger side tank near the trans cooler hook ups, a parts book can verify if your radiator is original.

The reason that I am suspicious about the Summit radiator you referenced is there were too many variations made for one size to be exact for all applications they reference. For example, I know that the diameter of the hose hook ups for Chevrolet and BOPs were not always the same.

If you measure for a replacement core, be careful that you and the manufacturer are using the same reference points.

I have visited your country and did some exciting horse riding in the south. Beautiful and sparsely populated are the words that come to mind.

Here are 2 other sources for radiators.

https://www.championradiators.com/

Champion makes Eagle radiators. They seem to have mixed reviews.

https://www.alloyworksplus.com/

AlloyWorks was recently suggested on our website.

Eventually, I need to get an aftermarket radiator for my 71 98. Make sure you avoid parts store cheapies that are made from aluminum and plastic.

Dear All; Just for closure I finally found locally here a good source who could re-panel the radiator, not cheap by any measure but still the cheaper option if you take into account shipping and customs, My original radiator had 3 rows of 1/2 inch tubes and instead of selecting 4 rows of the same tubes I choose instead 3 rows of 3/4" inch tubes which is airflow more efficient, Later on after installing and testing will update the result, if not satisfied I will go to US Radiator next. Thanks to All. Raul.

Raul, good to know that you found a local craftsman to repair your OE radiator. Make sure you post pics and an update once it's installed.👍
