[QUOTE="Don Bailey, post: 1008968, member: 70124"] Just had a new 4.0 long block put in my 03 Sporttrac and I'm not sure if its just air that didn't get burped out or what but I've had to add over 3/4 of a gallon the first time it was low and was overheating telling me it was low and had to add a good 1/2 gallon again and have had to add more for a third time. Turned on the heater and there may have been air in the core. Not sure. With a 3.5 gallon coolant capacity I was wondering if over a gallon's worth of air is reasonable? Not finding any evidence of a leak anywhere. I do notice dense white smoke/condensation at start up. More dense than I've ever noticed on a cold engine being started when its real cold outside like most do during the winter. Goes away after the engine has fully warmed up. Would antifreeze leaking into the engine cause a dense white smoke at start up until the engine warms up? Any clues would help my sanity bigtime! Changed oil and no evidence of coolant in that. No evidence of oil in rad either. Thanks gents! [/QUOTE]
