Has anyone had this procedure done on their 2020 gt500? I tried to inspect mine with a mirror but I can't see it with the oil filler tube in place, even with a mirror it's too deep and I can't angle the mirror enough to see the tensioner. I don't want to break the tube trying to twist it off. It seems easy enough to look at the tensioner based all the information I have found but I cant see it. Must be my old eyes. Went to the dealer, the kid was not informed at all. Told me I had to have the water pump removed to repair it....... ha ha ha ha ha. Did not even know there was a simple procedure to check and see if the tensioner was activated. I left immediately.
