Has any one used 40 Below in their radiator? If so how did it work out? Can it be added to existing coolant in system or do you suggest a flush and fill?

I've never used 40 Below---I have used Water Wetter in my cars for years (it's in the Vette)--the idea is these products improve heat transfer. I guess the question is are they "snake oil" ?? hmmmm... in my case many years ago i added water wetter to a '62 Plymouth we owned, the operating temp dropped 3-4 degrees as i remember in the summer heat. That's what made a believer out of me.
Now it's a part of what i add when i do a flush or drain and refill just as a part of maintenance. 
 
 A few things to keep in mind ,these cars run hotter by design then most people are used to seeing. If you're not sure of the service history on your car---then a flush or drain and fill is always a good idea.  Also be sure the the ac condenser and radiator fins are clean--these cars do collect debri from the road such as grass,leaves, plastic bags etc. Look close at the area between the condenser and radiator. Here's a interesting link about water-antifreeze and the above products

i personally never used any additive in my cars. i installed electric fans on my 75 and my 90 is original. as vaughn stated i just make sure everything is clean and no air restrictions.

Thanks. I did have a flush and fill completed when I first bought the car in August 2010. Car runs between 190 to 200 when driving with no traffic ( even with AC on) and anywhere from 210-225 in traffic. I will leave well enough alone for now. I will check to make sure all is clean. Thanks!!!

when you talk with the NCRS guys that have all the old timmer Vettes through C6's they all say to stick with GM recommended fluids...there's reasons! Even a stray splatter underneath the hood can ruin your fiberglass w/ bubbles years later. If you love your Vette, you take care of them the right way.
