Thread: dumb question but?

sounds good to me, its pretty funny. I took my in car in to get a diag and they said it was the tensionor. The car was making a whining noise from the engine bay, it turns out it was the water pump. It started spewing water everywhere. Not good. So I just replaced the water pump and put a new tesnisonor on there too. Next is to finish up the LIM and Valve cover gasket. I need to replace the vacuum lines I broke. So does anyone know why Duralast gives you 3 O-rings in the w/ the new tensionor? I watch a video from A1 on you tube and did not notice him say anything about those O-rings
