Hello I just bought a 1998 Cadillac Catera and I believe the Heater Core to be bad (smoke coming out the air vents/i hear like water leaking/bubbling from the dash/passenger floor is wet and there is a leak from around the firewall area underneath the outside i saw) How hard is it to change out the heater core, and what needs to be removed to do so? And could it be anything else wrong? Thanks Matt
