How are you supposed to add antifreeze to a 1997 Pontiac Grand Prix

When i put the antifreeze in the jar under my hood it doesnt hold it, and when i look to put it it the radiator cap its always full so why does my dashboard still say low coolant?

As for the low coolant light, there should be a sensor on the radiator that signals the light to come on. The sensor may be bad.

The plastic jug is an overflow container when the vehicle gets warm excess coolant from the radiator flows to it there is a sensor somewhere on the jug or in it for coolant level if it doesnt hold coolant it is most likely cracked as it is only plastic and should be replaced

You should look under the car after it sits a while and see if there is antifreeze on the ground. If so try to see where it could be leaking under the hood directly over the puddle. You could have a leaking water pump. If so there would be dampness under the right side of engine compartment. Also check the radiator hoses at front of car.

Remove the negative and positive battery terminal.
