Early vs later 99 radiators

Postby V4_guy » Wed Jul 29, 2015 8:16 am

Are later 99 radiators thinner than the earlier ones? I have a new Nissens 99 radiator that I want to have the end tanks from my 96 soldered onto (a common Sport & Rally modification) to drop into my 96 but both the tanks themselves and the core are thicker on the 96 radiator. I'm afraid this might not work.

there are a couple of different 99 radiators with the turbo radiators being multicored and thicker.

All the turbo radiators I've seen are the same thickness as the later 99 radiators but have a much finer fin count.

The early 99's (up to '75 I believe) had the thick tanks that match the 96 tanks.

the turbo radiators have what is known as a "High Efficiency Copper Core" - that is the "finer fins" basically more surface area for the heat exchanger.

A lot of people who have had them re-cored over the years have used the standard core, and are no longer good enough for a 99-turbo, especially one with AC.
Less brake more gas!

So is it unlikely that the thinner later core would work with thicker 96 tanks?

Definitely not going to work.

How feasible would it be to just have a radiator shop eliminate the 99 inlets/outlets and just solder in the ones from my 96 radiator with a coolant overflow tube on top of the left front tank. See my crude diagram:

I traded some parts for it a few years back. Are you interested? It might be in my best interest to just sell this one rather than go through the trouble of adapting it to fit my 96.

you might just get an aluminum radiator to fit in your 96.

I dug a Sonett radiator out of my parts stash that was in better condition than I thought. It's pretty much the same dimensions as an early 99 radiator but with the inlets and outlets in the right places. I'm having it checked out at a radiator shop today. Hopefully it'll be serviceable in my 96.

I'm not sure there's the demand to get a manufacturer interested :(
