I have a 2001 Dakota qc 4x4 4.7l. I am now on my 3rd heater core and once again in need of a new one. First original oem one went bad maybe 3 years ago. It lasted about 2 years. Installed now 3rd one and it lasted about 6 months. Problem is always the same small leak and steam when engine is warm and running. What could be causing these multiple failures.
Around same time my last one went out I believe I may have aquired a head gasket problem. Is it possible for a bad head gasket to damage a heater core.
