FYI: There are some fitment issues with the new aluminum 3-row radiators. I use the recored 3-row copper radiators. The aluminum ones require a special, non-50/50, mix of radiator fluid to prevent corrosion or funkiness in the fluid. The 3-row coppers also have a slight fitment issue, in that, they are thicker and there might be a slight tightness at the radiator wall window. Fairly easily fixed.

Thought the copper ones are no longer as well. I prefer copper too but can't be picky

I have like 4 used radiators sitting around. But I think I am using most of them. But if you really need an old one let me know.

actually, on my computer I keep getting aweird glitch I cannot translate this page, and when I choose english, I cannot find the one in your link.

I google translated, I prefer the high performance one.

This is their high performance radiator. Splendid Parts only provides this radiator now. It's a 3 core unit, I have one right next to me. It costs 289 euros, not including shipping.

This new cooler production (model 2022) was implemented exactly according to our wishes and specifications.

Do you drive a standard Opel GT 1900?
Then you are well served with this cooler, because it looks like a standard cooler and fits into your Opel GT without any changes. Your new cooling system then just has a little more power, which, as is well known, can't do any harm with the Opel GT. You simply leave the threaded connection for the additional thermostat closed if you do not want to use it.

Do you drive an Opel GT with a more powerful engine?
Then this good piece is also the best choice, as it is equipped with a 3-row high-performance net (series only had 2 rows). In addition, the cooler is provided with a threaded connection, in which a control thermostat for an electric fan, for example, can be connected.

• 3-layer high-performance radiator network
• Cooling core made of copper (no aluminum!)
• Installation dimensions and optics like a series cooler
• Thermal connection (with locking bolt)
• reinforced lower bearing plate
• Overflow hose holder + hose incl.
• extremely interesting price/performance ratio
  
  Please note! We do not send this cooler together with, for example, heavy brake systems, exhaust systems, etc.
  You may have to be prepared for 1x additional shipping costs.
  Delivery WITHOUT the shown radiator cap (item no. )

I was able to translate it and see that it's three row, and it's called the one for all or something like that.

So this one replaces all the other choices, and it's just the one from now on? I can't seem to properly view their website on my Chromebook. I can't find this choice while viewing English catalog.

How long did it take you to get your splendid order?

I ordered koni shocks and a bunch of goodies years ago and it took like 6 months.

 

[Autoholic]

Well, my order was shipped to Rav in Poland to come in crate #8. So it took a long time. Splendid was fast though.

 

[kwschumm]

One for all? So it comes with trans cooler?

No. But that's easy to add as a separate cooler.

You dont need a special coolant for aluminum radiators. If you buy straight coolant and mix it for 50/50 mix, used distilled water. The 50/50 already mixed fluid is mixed with distilled water.

Incorrect! OGTS even states in their ad for the aluminum radiators that they require a 70/30 mix:

https://www.opelgtsource.com/search/3541/details

<<< New aluminum radiator for Opel GT's equipped with an automatic transmission. Recommended for Summer driving and for performance-built Opel GTs. Installs in original location, and outperforms original-style radiators. Works with original mounts, and adds a convenient drain plug! (Note: Designed for automatic transmission Opel GT's - Manual transmission GT owners see our part #11023A). Requires a 70% coolant/distilled water mix for operation. >>>

I had one of the Honda aluminum ones for a while, using a 50/50 mix, and the fluid turned into brown goo.

Agree on the fitment issues. I got one from OGTS and had issues with the fan shroud fitting so i went back to the OE radiator. I gave the new one away with the one I sold on BAT. I recently got 2 OE ones on a parts car purchase that look like new. They are filled with kerosene / WD40 mix and sitting in a very safe place in my shed.

$350 is what I paid in expensive, high overhead So Cal to get mine triple cored when I did the engine rebuild. Always at or under half way with a 195° high flow t-stat.

Keeping the radiator isolated from the chassis & regular 50/50 radiator fluid changes are the most critical things you must do to keep ahead in the battle against the corrosion with the stock radiator in my experience.

 

[kwilford]

I do not agree with the need for a 70/30 glycol/water mixture. That concentration has substantially less heat removal capabilities than lower glycol concentrations. Any decent ethylene glycol brand has sufficient anti-corrosion additives to be perfectly safe regarding aluminum (or iron) corrosion at as low a concentration as 25%, so long as it is mixed with distilled water. And so long as it is flushed no less than every 5 years.

Unless, of course, you live in the Far North, where it can get to -40 F (which is the same in Celsius) or colder, since a 50/50 mix freezes at -35 F. Then a 60/40 mix will work, which freezes at -62 F. Ethylene glycol/water at 70/30 freezes at -84 F, and those temperatures are only ever realistically experienced at very high altitudes, near the polar regions.

For further clarity, Dexcool (the GM-type orange coolant) should NEVER be used at greater than 60/40 concentrations, as it may gel. Dexcool has superior anti-corrosion properties than the regular green variety, but must NEVER be mixed together. Or it will develop a sludge. Kinda' a brown goo. Gordo, any chance that your experience with said brown goo had Dexcool mixed with green ethylene glycol?
