good to doo

hey all, good to doo here, just wondering what thermostat to run in a all stock 91 sc with auto trans. when I put the engine in recently I used a 180 t stat. but now the the engine fan is not coming on. just wondering if the 180 t stat has something to do with the fan not coming on? and 1 more question are the 91 fans 1 or 2 speed. thanks for any help I can get. good to doo.
 
Put the stock 195 thermostat back in unless you have the ability to change what temps the fan turns on and off. All SCs had two speed fans.

And make sure you've purged the cooling system of all the air you can get out witch may take several cold/hot cycles. Your coolant temp gauge and fan turn on temps are going to be way off (temp gauge wise) until you get most of that trapped air purged from the cooling system.
