Check the radiator for any blockage. After the engine is warmed up and coolant is circulating good, the lower radiator hose should be pretty warm, just not quite as hot as the upper hose. If it feels cold, the radiator may have some blockage.
Sounds like you have covered everything else. Might want to double check for trapped air. Are you certain the temperature gauge is correct?
Let us know what you find out.

is there any air in you system i know from experince this cars can be stuburn and it also seems like a head gasket
SOURCE: 1999 Olds Alero leaking coolant and running rough
in my experience it sounds like a head gasket problem it maybe leaking into the cylinders or could be a small leak from one of the hoses I would do a compression test just to make sure and then pressurize the entire system using radiator and coolant tester if pressure holds then its not a leak as far as the fans go just have the car running when it reaches the middle of the temp gauge it should come one if not you may need to run check on temp sensor or fan switch and fans them selves I would follow repair manual troubleshooting section on heating and cooling haynes or chiltons will do.

There seems to be an air pocket or no antifreeze in engine block. Try this method disconnect upper radiator hose and pour water directly into hose down into engine block until it full. when its filled reconnect hose and fill up radiator. as the vehicle warms up open bleeder valve on the thermostat housing and release air from system. open slowly and BE VERY CAREFUL WATER WILL BE HOT, bleed until you get a steady stream opening and cosing valve. However if all of this don't work. You may have a bad pump. Good Luck

That cap was most likley broken upon pulling off. You need new wires.

problem could be heads bolts . i put new bolts in put a little sealer on them . make sure your bolt holes is clean free from debris. put a lillte sealer on intake gasket on top and bottom where coolants travel. if all was done . drain engine oil in clean container .set it aside. take radiator cap off .you a coolant pressure rise kit .put a pan under oil pan with drain plug still off .pressure your radiator about 10 psi. make sure you have antifreeze in radiator and engine . when you pressure up to 10 psi look under the car if coolant comes out oil pan. you got leaking head gasket. if not .put oil pan plug back on . put oil back in car . check your freeze plugs also.
Remove the negative battery cable. Using a screwdriver, loosen the screw that connects the negative battery cable to the battery post. Pull the cable away from the post.
Lift th car using a jack. Support the Oldsmobile Alero with jack stands and the engine using a lift or some other engine support device.
Drain the Oldsmobile Alero's colling system by opening the cap on top of the radiator and unplugging the drain plug underneath the radiator. Position a large container under the drain hole to catch the draining coolant.
Disconnect the components that lead to the water pump with an adjustable wrench Lay them out in the order removed. In order, these parts include the automatic transaxle (if equipped), front wheel on the right side, splash shield, water pump sprocket and the access plate to the timing cover.
Use the access plate bolts to secure the water pump sprocket holding tool to the engine cover. Remove the pump bolts, front cover, thermostat housing, water pump feed pipe and two engine bolts using the adjustable wrench. Lift off the water pump.
Remove the bolts that secure the water pump to the block. Take off or scrape away the gasket. Remove and discard the o-ring between the water pump inlet pipe and the pump.
Spread a small amount of sealant on the water pump, on the areas where it mounts to the engine. Place the gasket on the sealant. Position the water pump onto the engine.
Insert the new bolts into the water pump. Torque the bolts to 89 inch pounds torque. Reconnect the other components in the order removed using an adjustable wrench.
Re-insert the drain plug into the radiator. Remove the engine support and jack stands. Lower the Olsmobile Alero to the floor.
Refill the radiator with coolant according to the instructions in your owner's manual. Screw on the radiator cap. Attach the negative battery cable to the post. Close the hood and test the car.
