T-stat question

[tomtom72]

Hi Guys, I finally got the correct 1825-M spec coolant from GM so I'm going to get rid of the stuff the dealer put in my car. I figure on replacing the thermostat as I don't know how old it is.

My Q is if you are using a stock EPROM is a 180 stat worth getting? I'm not trying to be funny. It's just that the programing in the prom turns the fans on and off at some fairly hi temps. Will that programing work against the 180 stat? Will the 180 help in traffic or am I mis-informed??

I cleaned out my rad & condensor & oil cooler and installed a screen to stop stuff from getting back up in the cooling fins. I know I have a GM stat, 195*, in the system now. The cooling system responds when both fans are turned on and the temps come down. The temps are not a problem if the car is on the road but in slow traffic it gets up there and kind of stays at what looks like 200* more or less.

Thanks for any advice you want to share!
