. seriouly. i was driving for about an hour and a half and it overheated on me . So yeah it was different this time though. i had no serious amount of coolant in the overflow, rad cap is sealed right, fresh coolant, distilled water. i followed all of the instruictions and did it right. Still over heated. okay now from where the smoke was coming from. it was coming from where the thermostat area is, but like directly behind it. where all the electronics are. i had pressure in my op rad hose as well. any ideas guys? im thinking BHG :wtc:
