Nice work. I've replaced the wrong part before, but I learned a lot from it. Something was dripping on the exhaust manifold, so I replaced the heater core because it was in the right place, and coolant runs through it. It turned out to be the head gasket that needed replacing, so I got to do that, too. I'm in a different place now financially, and will never do either of those jobs myself ever again.
Oh man, two of the worst lol.
I learned so much from replacing things that weren't the problem. In the moment, it's such a a pain but it's taught me a lot and been helpful in the long run.
Sometimes it's the only way to really figure out what's broken.
