what coolant should i go with, i live in fla, and will be driving in 90 degrees+ weather, im using a fluidyne rad.

 

I would use more Water that Antifreeze

Like 35% Ant to 65% Water

You will never have to worry about Freezing

 

And its commonly available.

 

Any typical ethylene glycol coolant (Prestone) with DISTILLED water. For Florida, you should be running a 25/75 coolant/water mix or so. No need to run more coolant, it's only there for anti-freezing and anti-corrosion properties.
