Question about 2002 Oldsmobile Alero
If its the thermostat your lucky easy fix just replace it but wait until the engine is cold the bolts are a nightmare to get to you have to take off air hose and disconnect a couple coolant hoses move them aside to get to the thermostat housing on the side of the engine tricky getting to that bolt.
if its the head gasket flush the radiator with flushing agent
first drain the coolant from bottom radiator hose replace with flushing agent run car idle about 10 minutes then
remove the thermostat replace the thermostat housing then fill the coolant back up leave room for blue devil head gasket sealant about $65.00 follow the directions to the tea run for 50 minutes if it doesn't work that baby needs to get in the shop
hope this helps don't forget to rate if I was helpful.

Ok here is a few thingsto look at
check under the oil cap see if its creamy if it is blown head gasket
run car till over heat or get hot stick your hand in the middle of the radiator if it aint that hot no water is going though the motor to cool it so the thermostat is blocked
