im worried about pushing that 240+ which i hit pretty quick ne help thanks for

 

Are the fans running?

 

Make sure you have enough coolant in the system, too. Crack the bleeder screw and open the radiator cap. Fill it up if it's low. 9 times out of 10, overheating is caused by not knowing how much coolant is in the system. I had the same problem. I thought my levels were just fine. Come to find out, it was nearly bone dry, due to a parasitic leak at the water pump. After replacing that and filling the system back up, I'm in city traffic and she's holding just below 200F.
