Check your cooling fans. There are two. If even one is busted, or so much as running at less than full capacity you will not be able to idle indefinitely.
The engine is overheating.
a 2002 Alero could have several problems causing the overheating. Thermostat, water pump, or clogged radiator issues are the most common causes of overheating.
If overheating while moving it could be brakes dragging or emergency brake on or bad bearings in wheel. If overheats when idling could be bad timing, seized alternator or idler pulley bearings.
Several possibilities - from easiest to most expensive: Faulty or inoperable radiator cooling fan - causing overheating. Faulty thermostat - causing overheating. Water pump failure - causing overheating. Blown head gasket - allowing exhaust gasses to escape into the cooling system and expelling the coolant.

Possibly your radiator is not big enough. Or that radiator could have internal clog witch results in only us in half of the radiator. Or your fan is not pulling enough air though it
It's not always the case if your car is overheating. This could be a sign the head gasket is bad but many other things could cause overheating as well. If your car got hot or runs hot it won't always require a new head gasket
The white smoke could be valve stem seals. The overheating could be a partially blocked radiator. Don't bother trying chemicals to clean it out. Take the radiator to a shop and have them professionally clean it. could be a blowen head gasket!

There could be several reasons why a 1991 Celica is smoking. Engine oil could be on the motor to make the car smoke. The also may be overheating causing it to smoke.
Typically a cotton-tipped applicator will get wedged in due to the partial vapor pressure of carbon dioxide.
