well I'm new to the site and just bought a 04 GTP it was starting to run warm and started surging a little got it home and started smelling anti-freeze so looked around can't really see any leaks but through a little research I'm guessing its the LIM gasket how hard is itit to change or better yet anyone want to make a little extra cash by the way it was a little low on coolant so I refilled and bleed the system and no change
