My tensioner seized and I pulled off the old one,i un bolted the radiator support to give me more room but I am having a heck of a time lining the bolts up.There's a small L shape pin that came on the new tensioner, does anyone know if I'm supposed to pull that out before I install it or after it's bolted up?

These are just a pain, I start the big bolt first, then pry and maneuver the bottom around and try and get the 2 small bolts to start.The pin holds it in a compressed position, and you can just put the belt on and then remove the pin and it tensions the belt.
