Question about coolant temps

[km346]

Hey all,
I recently took my SS for a ride with the scan tool plugged in. I realized that my coolant temps where sitting at 200-205 while at cruising speed. Is that normal for a stock thermostat in our cars? Just wondering.... seemed kinda high to me, what do you guys think?

Thanks

perfectly normal. hot coolant temp is like 235 to 240ish. Overheating is 250 to 260ish

Thanks for the response Cutlass... I know our stock T-stat is 195 degrees but for some reason i thought that was kinda high. I plugged the tool into my truck which has a 195 T-stat and that seemed to run around 187-190. I guess the large grille and fan clutch setup on the truck is making all the difference. On a side note I noticed my FTRA set up is keeping IAT temps very close to ambient air temp which is good.

i thought stock stat was 180 ?

Stock thermostat is 195-198 degrees with the fans set at something like 212 and 224 degrees. With our 180 degree thermostat and reprogrammed fans I finally saw a high of 205 on the scanner idling in traffic this weekend on a 90 plus degree day with the AC on. Usually runs 185 to 194 for the most part.

Yeah it seems 15 - 20 degrees over t stat number seems norm I guess. My 160 seems to run about 185 in high heat w/no AC.

keep in mind that the t-stat rating is just where it opens....the fans control the temps after that.
