NO WAY--I don't care what they say--that's too HOT---Make sure your fans are working--
the 1st fan shold come on as mentioned at 226* But to check the 2nd fan just turn on the A/C and it comes on automatically regardless of temps--
Check you incoming radiator shrowd for leaves/papers/debris--clean it out--
BESTwould be to get a mail-order tune to have the fan settings to come on earlier and better yet install a lower degree thermostat and all your coolong issues will be gone
I like the 160* thermo---It won't run that cold--usuually stables out to run around 180*
set the fans with a 160 as follows:
1 on at 190
1 off at 185
2 on at 200
2 off at 191

Normal ACCORDING TO whom ?? THE PEOPLE TRYING TO SELL YOU A NEWER ONE ???If you use racing as a testing ground/benchmark --they try to keep the eng as "cool as possible"
EVEN more so (IMHO) on a computer controlled car where you get false IAT temps that spike up to 170* falsely by reading undehood temps instead of incoming air----THEN the ECM removes up to 10* of timing !!!!
ALSO-- Its an old wives tale that the coolant has to be 210-220 in order for it to pass smog---
ALSO an old wives tale that running the cooolant at 180* won't let the oil temps get hot enough to boil out moisture--( on my car that runs from 175-185) the oil temp is still always 250-275*
Reducing coolant temps is good for so many things
LESS false IAT spark deducts
LESS fasle ECT spark deducts
Hoses last longer with cooler underhood temps
belts last longer
all rubber and plastic deteriorates less
seals last longer
less chance for gaskets to create oil leaks-
With everyone using thinner 5w-30 or 10w-30 oils these days the oil comes up to temp very quickly anyway--When in the 70-80-90's people ran st8 weight 30 oil that needed to get hot /stay hot in order for it to flow in cold weather

NORMAL according to GM who made the car!
