ACDelco 10186118 GM Original Equipment Drive Belt Tensioner NOS

I have a piece of "unobtaineum" according to some experts. I got this many moons ago for my former LT1 wagon but it never got installed.
I imagine only a select few

looking to restore a nice example would want a new part rather than an old used one pulled from a donor.
$250 shipped - unless outside USA.

have a used one available - from a 1996 wagon - pulley spins freely - screwbolts aren't buggered... $70 shipped to usa included

If this part is still available, would you message me payment info.
Thanks

Sorry it just sold earlier today

If anyone has this part please let me know. I had to replace the pulley about 6 months ago. I couldn't find the pulley anywhere so I found a pulley with the same belt pattern and bearing size it was actually a little to big Diameter wise so I took it to a machine shop and had them shave the pulley down to a diameter that would fit the tensioner. I also had to have the tensioner itself shaved down a tiny bit so it wouldn't rub. Worked great for about like I said 6 months then I had a issue with the harmonic balancer which I actually had misdiagnosed as my alternator, then my power steering pump which I replaced both and didn't have to then they finally seen that the crankshaft was completely stopping when I would turn my wheel. So I replaced harmonic balancer and everything worked great but my tensioner itself broke now from all the on and off. Not sure if I can be rebuilt or what type of machine shop is needed.

The spring is what fails, so you need to look for a spring manufacturer.
