In Reply To	what causes the heater cores to need to be replaced? posted by LJZTT on February 04, 2017 at 11:47 AM
Message	1. clogged w. rust and sludge - no heat 2. leaking vanes in the core or tubes - leaking out of lower vents 3. leaking flow valve - leaking out of lower vents Other problems could be the mode door motors being dead or stripped threads and inoperational defrost for example. A new core comes as an assembly w. new tubes attached.
