40 Below
Im looking to lower my coolant temp and I think 40 below seems like the best. My question is should I mix this with the Dexcool or should I mix it with something else? I live in florida so cold weather is not a problem for me. And how many cans should I use

They say it is safe with Dex BUT....
I put this in my Corvette which had a totally clean cooling system and several months later there was a heavy brownish mud/tar-like stuff in my rad. It took a lot of work to get the system clean again. I have owned many cars and never saw anything like this happen before. I never did anything else, other than add the 40 Below, which could have caused this. That is my experience with 40 Below. Plus it never lowered the temp at all.

No problems with it in my Z06 and I use Red Line Water Wetter in my Dodge truck. 
I wanted to see how they both worked and so far so good, no problems at all....
