My 99 alero keeps overheating , and the colant is full .when i shut off my car it sounds like gurgling
Theres air, a lot of air in the system.
You need to have a pressure check of the system done
Could be bad radiator cap, hose (multiple)... any leak will allow air into system during cool down.
If the surge tank level doesnt go down after a hot to cold cycle, then theres an air leak.
Could be a bad coolant pump, could be a clog in the system, could be a bad cooling fan. You're building up a lot of heat and pressure while the engine is running. When the engine shuts off that pressure tries to equalize which causes the gurgling. Most mechanics will have the tools to flush and to pressure test your cooling system.
Sounds like the radiator is clogged. Take it to radiator shop and have it flushed

Is your security light flashing when it does this? If so, it is going into anti theft mode. Do you have the correct key for the car? Not an aftermarket one either.

hi, i dont know about the dipstick, but your overheating problem is most likely to be the thermostat...sounds like its stuck in the closed position,not allowing colder water to circulate, hence the overheating.......needs changing

Could be both your water pump and thermostat are faulty. Start with the simple and replace the thermostat and also did the engine over heat while you were stopped or in stop and go traffic, if you were then you may have a blown fuse or bad cooling fan relay that needs to be addressed. Check to make sure your Cooling fan is working, you can test this buy turning on your A/C on full and the fan should come one the same time your A/C clutch activates. If the fan does not function, inspect the electrical system to the cooling fans and replace the thermostat to ensure there will not be any issues in the summer time. Thermostat are know to go bad when they are over heated.
