Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Which is best?

I am doing some pretty major mods to my car right now and I have noticed that while I have the motor out it would be a good time to replace the coolant....What my question is which coolant will keep my car the coolest? I have a 160* Tstat but would still like to make sure it ran as cool as possible.
 


changing coolant won't help it cool better, and keeping the car cold doesn't do anything for performance (just fools the computer into dumping more fuel)
 
yes get all the dexcool out of there. you can do a search for the Dexcool threads....

I would change it out to normal green coolant. your radiator will thank you!
 
I prefer the yellow works with anything stuff myself, just in case you don't get it all out, or a shop decides to add some
 
The way to stay cooler is to a 30/70 water/coolant mix in the summer. Just remember to add more coolant before the first freeze.

FWIW, you would want a 30/70 coolant/water mix. The more water you run, the better in the summer.

I knew what you mean, I think you just got your mixes all worded up.
 
my car ran 10-15° cooler when i dumped dexcool for slandered green.
This was messaured by scan master and a tech II.

Now in my regal i changed dexcool when i did LIM and i dropped a from dead center tick to half way to the next lowest tick with just green coolant.
