Hey everyone i have a 92 camaro with a 305 v8 and the other day i did a radiator flush and after that i drove it a couple days and like two weeks ago. I believe monday i was driving down 46 and pulled in applebee's and out of the motor there was a lot of white smoke. I opened the hood and for some reason the coolant reserve was full and spilling out warm antifreeze which should of been green but was brown and smelt like burnt popcorn. I had no choice drove the car home with the thermostate gauge piniped on 250 the highest the gauge reads. I got home and let it sit the night and the gauge went down and the fluid dranned back into the motor. Now i thought the thermostate was gone so i went bought another one that opens at a lower temp. and put it in. I drained the old fluid and put new one in and started the car it ran and all of a sudden it happened again with the new thermostate. Know i don't know wat the hell it is and i want to fix it and i don't know what to do and if anyone can help or come look at it please let me know. Asap
