My '99 Grand Am GT just recently started overheating, but only if it wasn't warmed up to about 175 or 180. Coolant is full until it overheats. After sitting in idle for about a minute the overheating subsides and it drops quickly to just under 200. No unusual sounds are heard and no smell of coolant. Some smoke in the morning but when warmed as mentioned this goes away after driving just maybe a mile. What could this be?
