Question of those who have done the job - what is the likelihood that my heater core is actually bad vs just the input pipes and o-rings?
Hi Jeff,

I can only comment on my own past two experiences... both times I've done it, it sure looked like it was just the o-rings, but I didn't take the time to pressure test the core. I just figured a new one would be worth putting in just in case since I had the whole thing apart. I have never done the tubes, just the core itself + new o-rings. The tubes looked like a whole new level of effort; the core alone was work enough!

Hope all is well up your way - and that you have a good Holiday/Solstice/Etc or whatever you're allowed to call it these days
