when the heat is added to the ac from the evap core, the factory cooling system just can't handle it. this gets WORSE not better with big thick aftermarket rads as the fans now have an even harder time pulling enough air cfms through the "bottom breather" design

the factory rad although pretty crappy, (end tanks) is remarkably cheap and efficient as long as you are moving

in temps like today's (wow it's HOT) AC on creeping in traffic for sure equal creeping temps on the coolant

here's what you can do

run water wetter and pure water. coolant isn't as efficient

just make sure you run enough watter wetter to keep the coolant chemicals in there to prevent corrosion (sacrificial anode comes in handy there)

cooler thermostat *(I've got a nice spare 165 if you need one)*

fans on full

most importantly of all, clean the crud out of the rad core at this point I'd pull that rad out and just change it. a fresh one is cheap, flows better.

wish I could still get the fluidyne. it had the thinner more efficient cores

my other thought is the dewitts fan kit

if the wazoo boys want to give me a hand with it. we can do some before and after testing!!!fahne
