Originally posted by liquidX: Well, stock thermo's are 225/220, but the Advanced Auto Parts replacement is 195/192.
Tom meant the stock fans.
Also they come on at 216/224 like I stated in my post.
The stock t-stat starts to open at 190-192.
A 180 t-stat start to open around 180-184.
A 160 starts to open around 160-163.
A t-stat only controls the minimum temperature when that temperature can be sustained by ambient temperature and the efficiency of the engine's cooling system. (coolant mix, radiator, fans, w/p)
In my setup I run 70% water / 30% Zerex OAT with water wetter, fans on at 186/196, SVT radiator, revised w/p, and 160 t-stat. Normal operating temp is 175-185.
It's rare the primary fan kicks on unless I am in bumper to bumper traffic in hot weather.

It was not broke; Yet I fixed it anyway.
