I have an 02 ss went to go to work and I have no heat? Was working before.

 

Check for any water/antifreeze in the passenger floor. If so, heater core went out. If not maybe the blender door is stuck that changes from air to heat. Does the air blow cold?

 

Yes it blows cold, this is the op couldn’t get into my other account for some reason.

 

And if doesn’t look like any water/antifreeze is on the floor.

 

Do you smell any antifreeze under the hood?

 

Yes I have noticed it smelling like that

 

Also checked coolant and didn’t have any in it.

 

Refilled coolant and a few days later no coolant again.

 

Definitely a coolant leak, you need to get it pressure tested, put a pressure tester on the radiator fill tube and pump it up, then see if you can figure out where the leak is. Could be any hose or the radiator or coolant elbows that go from pulley tensioner to the manifold. Best case its a hose worst case could be a head gasket.
