Good Afternoon Gents... I think its finally got me. I have pretty much all the symptoms saying my heater core is on its way out. Coolant smell, film on windows, smokey vapor from the vents occasionally. Everything seems pretty ok as long as i keep the AC on low but thats not a fix. Im not losing any significant amount of coolant since i havent had to fill it at all since this has started. I was looking into replacing the old girl but ive decided im gonna keep her and replace it myself. Any tips, tricks, writeups, videos you all recommend? I wanna get all my parts and ducks in a row before i tackle this over a weekend with a friend.
