I don't know if this is the right place to post this thread
well I have a 160* thermostat i don't have any over heat issues
my coolant temperature never exceed 205 but i have a problem when i stuck in a traffic jam my fans keep working hard together and after 15 min my alternator voltage keep drooping until 12.8V
my fan settings as my tuner make them :
both On at 201
both off at 190
are those good settings ?
i think one fan should work first then if the temperature keep climbing then the other one should work to support first fan.
and yes this is a new alternator and new battery

Fans ONLY operate together. They also have a low and a high setting.
I think you need to have the alternator checked. I have an under-drive pulley and a normal output alternator and a 1,000 watt stereo amp on my 427ci. When my fans come on when I sit in 95* traffic for 30 minutes, A/C blasting and my stereo on, my volts are always perfect.
Also, no matter how hot it is outside, if you have a 160 t-stat, when it opens up and trades the coolant from the radiator to the engine....your fans should definitely shut off completely for a little bit. Maybe you have a stuck open t-stat too.
