Hey I have a 2008 pontiac g6 gt and I have to keep adding coolant and there is no heat unless you step on the gas and there are no apparent leaks and no antifreeze in the oil that I can see and no antifreeze that I can see around hoses or the block. Water pump or heater core or intake manifold gasket what do you think?
