radiator....
Well my radiator cracked wide open on the highway yesterday. Before i buy a new one to replace it. My car seems to run about 230 all the time anyways. I figured a 2 core radiator would help. Ive replaced the thermostat and checked my fans and burped the tank, still runs over 220, especially at 70, it will reach 240 at that speed. Do they make a 2 core radiator to fit in my 98 coupe?
I noticed that the 06, 6.0 corvette radiators are close in dimensions and are 2 core. Has anyone tried installing one of these in a c5? Can it be done and is there a lot of difference between them. Thanks for the help!

Cleaning out you system may have gained you a lot better performance and maybe saved your stocker. Since you need a replacement:

i found a real good deal on a 90' corvette 2 core all aluminum radiator. Looks very similar to my 98 radiator. The dimensions are a little different give or take an inch or 2, will this work? Anyone familiar with this?

a larger radiator will allow it to run right at what t-stat you choose
with my dual core and a 192 stat, it runs at 192 with the AC on in 120 degree heat , stopped in traffic
you do not want to run the car at 160 or even 180 for that matter
you have an aluminum block
they need heat w/o overheating

Here we go again with mis-information on thermostats. A thermostat will not keep your engine at a specific tempature. It is designed to keep your cooling system in a closed configuration until it reaches the thermostats tempature rating, at which point the thermostat opens and runs the system in a continuous open loop. The engine temp continues to rise, at which point the radiator and fans are responsible for cooling.
Think of it like opening time (thermostat tempature) at your favorite parts store (cooling system). If the sign says open at 8am, then you have to stand outside until 8 am. Once it reaches 8am, the door opens and you can walk around the store all day long. While walking around the store, you rely on the stores air conditioner (radiator and fan) to keep you cool.
And to the OP, as soon as my radiator gives up the ghost, I am going with a Dewitts with the trans cooler built in. Heat kills your transmission too.
Hope this helps and good luck.

the t-stat keeps the engine an a minimum operating temp , that's it , pure and simple
a big radiator keeps you from getting too hot

Also the difference between 3 row alum. and 2 row. The 3 row is made of 3-5/8" aluminum tubes and the 2 row uses 2-1" aluminum tubes. So the 2 row aluminum radiators have more tube to fin contact area, which is better. This is an industry standard, not just DeWitt's radiators.
Here is a picture of our C5 Manual radiator. It has the right mounting for the fans and condensor. That '90 style you saw, you would have to modify in order to get these to fit.

Hope you find this useful,

Hi Justin,
I just replaced my rad not more then a few weeks ago. I had the same failure as yours, my tank took on a 4 inch split on both sides. An aluminum rad is ideal of course, but if you don't want to spend the money and your car isn't highly modified I suggest that you take a look at 1-800radiator.com
I bought a 2 row aluminum rad with plastic tanks for about $140 bucks. My car is a 2001, and the rad lasted 9 1/2 years which ain't to bad. Yours is a 97 and lasted until now, so although the stock rad can't compare with all aluminum, it still did the job pretty well. If you have the money, obviously go with dewitts aluminum, but if you don't want to spend then choose the aluminum 2 row with plastic tanks. It will do you just fine for the next 10 years.
cheers
