Review on 🔧 Dorman 419-015 Automatic Belt Tensioner: Optimal Performance for Smooth Belt Operation by Brian Krump

My last few 'GM' or AC/Delco parts came in boxes marked 'Made in China' and I don't mind because they're pretty are standard. The Dorman stuff is reliable and, as far as I can tell, identical in function and design to the OEM. There are many third-party manufacturers that make replacement parts, some of which are pretty patchy. In my experience Dorman is reliable and they care about their brand and reputation. This part, of course, was somewhat identical. I also like the compound role. Works truer than the metal style I replaced.
