Had to install tensioner several times, only way to keep it between the 'posts' is to over tighten which slows the bearings and scrapes the belt tuft. It worked for 5 minutes before I turned it off. It has stood the test of time so it was cheap but a good lesson not to buy cheap parts for something as important as a timing belt. I'll be buying the original kit today, even though I'm considering removing the water pump, why would I think it's better than the rest. Good thing I'm not picking the valve parts out of the pistons!
