Just put in a new cam 160 t stat and water pump in. It will stay normal for a few then start getting hot pretty fast. Tried burping it for a total of about 13hrs even on a dramatic angle and 3/4 of a tank of fuel and both. I have changed the reservoir cap (since that's all the 04s have) and still nothing. Also water will boil up and puss out the overfull tube. Any ideas on a fix?
