Off!!
bad water pump
take off the rad cap when its cold and then start the car and pour 50/50 antifreeze into there tell full leave car running with cap off for about 5 mins to get out any air it might drop just top it off
To change the antifreeze on a 2003 Alero once the car cools remove that radiator pressure cap. Pour in a gallon of pre mixed coolant.
you open the plastic bottle and pour in the antifreeze
No offense, if you don't know where to pour the antifeeze you probably shouldn't have a car at all.
cap is off
Failed hose, water pump, freeze plug, intake gasket..........
Check Your Waterpump
water, gas, oil, antifreeze, ATF, brake fluid, gear oil, windshield washer fluid,
The engine is overheating.
The smoke is actually antifreeze mixed with air. The most common cause of this is a leaky heater core.
Pour it down the hoses that let the water in. Turn it on so it sucks the anti freeze into the pump...about thirty seconds out to do it and pour some more in the hoses and cap them off.
