It looks like it is time to replace my heater core. While I am in there I plan to change the A/C evaporator and the accumulator. Am I missing anything that should be replaced at this time? Looks like Napa, Auto Zone, and Rock Auto all have the same heater core a "Spectra Premium". Has anyone had any bad luck on the evaporator and the accumulator on a specific brand?
I have watched a video on removal. Any tricks that I should be aware of? I know the blend door is important to position that properly. Any advice is appreciated!
