Lately I've had to add coolant to my 2001 Pontiac grand am about every 2 weeks especially if I use air conditioner or heater. Is there a leak somewhere
You most likely have a leak coming from the heater core or the lines connected to it.
Do you have white smoke from the tail pipe? ??? If so you might need a new head gasket
Should go to a shop and have them pressurize the cooling system and checked for leaks.
