I know its summer, and yes the engine is going to get hot but what temp should it be at? I dont know if its normal but yesterday I was driving it at the hottest part of the day and it was reading 240 and then i turned the car off then turned it back on and it did not start i had to give it gas for it to start, and when i went to rev it a bit it sounded horrible like it had nothing in it. If i changed my stat to a 180 instead of the original 192 would i need to tune it or can i just swap them out. What else could the problem be? The motor only has around 1200 miles on it.
