I recently bought a used 2014 CX-5 with about 80k from a dealer that turned out to have a bad heater core. The dealer is going to replace the heater core and pick up most of the cost of that job. I understand this is a pretty extensive job involving removing lots of parts. Are there other things I should pay to have replaced while the mechanics are in there? I'm not aware of any other problems just wondering about preemptively replacing things while the car is apart. Thanks for any feedback!
