How hot is too hot?

I answered the question you asked in your post for the poll. I didn't see that there were two different questions until after I voted.

I think 229 is too hot but 230 is even more. The optimum operating temp is usually around 190-195 if you can keep it there. I'm happy if mine stays between 180-210 on those hot July days.

Engine Temp

I think anyone with a LS is going to vote 200 230

Just had a talk with my ECM provider his temp marks are?

fan 1 turns on at 205
fan 2 turns on at 210

LS's can run with no problems up to about 230

Yes, this was my first time starting a pole so I was not to sure how to start it. Thanks for answering.

My car is running around 190 while I'm driving but when I sit in traffic it can climb to 230 while I'm sitting.

230 is a little too hot for me. Usually if your engine runs cool while moving but overheats at a standstill, the radiator and water pump are doing their job. It's usually the fan that could use some improvement.

I answered 160-189, but that depends on what you are trying to do. If I am drag racing, I want it as cool as I can get it which is way below 160, but for cruising around I or in traffic I have my fan set to come on at 190 and will cool it back down to 175 and go off. The fan never comes on driving down the road, only sitting in traffic. Even on 100 degree days it never goes over 190. A warmer engine is usually more efficient and that is why the oem's run them warmer, plus it helps to "burn" off [emissions] in the engine.
As far as the too hot goes, I would not want my car to get to 230, but I also do not run a high pressure radiator cap. I have seen engines get way over that and not hurt themselves but not for an extended time period. My Dad has a 57 chevy and it would run hot. We tried all kinds of things to keep it cool and it would not cool down. He has seen 250 with it and never hurt it. The only reason he let it get that hot was he was stuck in traffic in a cruise and had another engine built to go in it.

I knew a girl who used to run her 350 at 280 degrees!!!!! she was as dumb as a box of rocks though. That engine eventually did blow up though (go figure) however it was only because it threw a belt and she kept driving it LOL!!!!!

and then she wanted to rebuild it

I would say if your engines running at 190-200 its fine anything over that is too much for me

I voted for 190+ cause Im fuel injected and its just a street car, looking for a lil economy JR
