I bought & installed a 2 row all aluminum direct fit radiator from ebay. nice except annoying sensor prong leak.

I was concerned if my old stock transmission cooling lines would fit. they did.

 

Repair of low coolant switch worked and driving to work car kept perfect temperature. Check repair at lunch saw another small leaking part just below radiator cap... Time for more Blue RTV... at least the fixes are cheap and easy...

 

Are those leaks defects from the manufacture?

 

That radiator looks identical to the Champion radiator.

 

yes, nice except for the 3 o rings.

 

On the strength of reviews from here, and other boards, I bought one of these in October.
It arrived in the UK in November, and was fitted on the 10th.
Over the last month, it's been losing coolant - today I think I've tracked down where it's leaking from. Looks like the fins just near between the upper filler neck and trans cooler inlet were wet and dripping. It's a small leak to be sure, but a leak nonetheless.
Also, it's by no means a direct drop in replacement. My garage have had to fit it canted back at a slight angle, chop the top of the shroud to clear the filler neck and weren't able to fit the rubber isolators at all, which means it's an ally rad sitting on the steel support - not the best situation.

All in all, I'd recommend spending a little more.

Edit:
Also, I've never seen or heard the fans cut in, even when the temperature's reached the red line on the dash!

 

I understand this is a seven year old thread but it's an issue that these radiators continue to have.

My second American Eagle radiator is now leaking and it's leaking in the same manner my first one leaked which is also the same spot yours is leaking: The junction between the crossover tubes and the side tank. I've reached out to American Eagle and thy agreed to give me a Return Authorization number but all that means is that I can ship it to them on my dime and they will decide if they want to replace it. Not sure if I want to take that $30-40 gamble or just buy a different one...

 

My research has shown that it is made by Champion but most likely they all come from the same factory and are rebranded.

 

Ran across the same issue on a C10 I was working on a while back. They do make a 1/4 flare to M12-1.25 ORB fitting. Sealed right up.
