Nope, I ended up using the black ones. The Regal springs are rated for 200 pounds less than the GP springs.
So now I have belt squeak that will not go away, after 3 belts. I just discovered that my idler pulley is making a bit of noise, and my water pump has VERY VERY little play in it, and is still damn near silent when I spin the pulley. I think I'm going to start by replacing the idler pulley and see if the squeak goes away. I don't think that it's the tensioner itself, because when I turn the A\C on and\or crank the steering wheel over all the way the squeak doesn't change. Anyone have any other input on the matter?
I've tried 3 different sizes, the smallest possible is on it now. I tried the next size smallest and it doesn't fit. The tensioner's pulley does make some pretty good noise, but it still rolls smooth...that could change with the belt's tension on it though.
They do, but the squeaking doesn't get any worse with added belt-load (air conditioning on, power steering maxed, etc.), so I don't think it's the tensioner. I think I'll have Oreilly's order one just in case the pulley doesn't fix it.
