I have a 95 Z28 and it ran fine or at least as good as every other one as far as tempertaure is concerened until i put my wingswest body kit on it. My car will warm up about to 220 , 230 in the middle of the day when it is really hot and im runnning the ac but at night i have no problem at all runs consistently at 175, 180. I have a manual fan switch which really helps but I still want to make it run as cool as possible. I heard i should put a 160 degree thermistat in it but i dont you have to reprogram your car or something before it works efficiently. I need to know what i need to do with the 160 therm and any other suggestions would be awesome. Will someone Please help me!!!!!!!
