In general, yes a coolant leak in a 2002 Bonneville can be fixed. The issue whether it is worth the money to fix the leak. If the coolant is leaking from an upper or lower coolant hose, the repair is simple and inexpensive. If the coolant leak is from the radiator, it will be a bit more difficult and/or expensive to repair. Moving up the scale, if the coolant leak is coming from a manifold gasket, it will be still more expensive. Likewise for a coolant leak from the heater core. And at the upper end of the scale, if you are leaking coolant from a cracked engine block, you're looking at replacing the engine.
Your dealer can tell you if there is a complimentary repair for this. Sounds like it has a leak and is low of refrigerant.
