05 yukon xl oem thermostat temp
does anyone know what the thermostat temp for a 05 yukon xl 5.3L flex fuel is? I have looked at some part stores and seen 187 F, 186 F, 180 F, 190 F. Any ideas which one is correct?

Most vehicles have a stock thermostat temp of either 190 or 210. I would lean towards the 190 based on the options you have to choose from. I want to say my Vortec 350 was 190 but it's been almost 4 years since I've owned it so I'm not certain on that.93 Suburban (Southern Slayer): TBI 350, 4L60E

I did some research today. It looks like it calls for a 187 degree t-stat.
