Temp too high ?

If it starts going over 230 I will get concerned, as soon as it goes over 235/240 I will shut the engine down, nasty things can start happening when you get much over 240. Anything below 225 should be fine, you should see no damage, but to be honest I prefer to keep the engine temp at 200 at the most. Around town I like to see, light to light lots of idling, 200 maybe 210 max in the middle of the summer, if the car is moving above 25/30 MPH close to 185, or just over the 180 thermostat I like to run on street cars.
