My radiator began to leak from the top plastic part where the serial # is last week like another forum members did. I did the easy fix and sealed it with JB weld. Now it is leaking on the passenger side lower part. It isn't visible from looking down into the engine bay. But I will be putting it on a lift tommorrow when I change the oil. My guess is it is the radiator itself or lower radiator hose. Hopefully just a hose.Fluidyne replacements sound like the most used so that is what I am looking into. Are there any downsides to these radiators besides cost? Just looking for product reviews if i have to bite the bullet and get a new one. Cheapest I have seen is 412 anyone know any cheaper? Thanks for any input.

Is it stock replacement or a "universal version"? How much did it run you?

Rotary Performance sells a stock all metal replacement for $250.
I had one for 2 years and it cooled just fine in stop & go traffic during the FL summers as well as during autocrosses.

If you look around you may find one as cheap as $200.

it was a stock replacement. it was $191 but it has a lifetime warranty so its all good

But it won't cool as well as the Fluidyne because it is brass.The Fluidyne is aluminum.I had the brass one from RP and after I got my temp gauge and electric fan played alittle musical radiators with it and acouple stock ones I picked up used.The stock one seems to recover(cool down faster)after hard driving than the brass one.The Fluidyne should outperform the stock one.Note that you can't see this on the factory gauge it doesn't seem to move once the car is up to normal operating temperature.
