Completed desmog taking great care following desmog threads on this site. Started right up sounded great but began immediately overheating and didn’t seem to be pulling coolant into block since I was trying to add coolant needed from some loss after pulling lower valve off thermostat. Thought maybe overtightened belt on the new pulley and damaged bearings in water pump so replaced pump and coolant temp sensor. Apparently wasted all that time and money because just started her up and immediately overheated. Again it doesn’t seem to be pulling coolant from radiator at all since again I was trying to burp radiator after filling to complete water pump project. I guess question is what vacuum line(s) misplaced could cause immediate and rapid overheating? Any suggestions appreciated.
