Turn the two screws next to the throttle body till coolant comes out. One is in the middle of a hose, one is right next to the throttle body.

i would say the sensor is either not plugged in or crapped out on you which is very common.

if your car came with green coolant don't mix it with red. stick with what it originally came with...

The low coolant light sometimes takes a few cycles to settle down after you drain coolant, so dont go rush and get another sensor yet..
DO however, pay attention to the overheating situation tho...
