Review on Performance Tool W89399 Remover Installer by Terrance Castle

This tool sounds like it will fit MORE 10mm and 13mm screw heads but not 13mm screw heads. not even close!. I used it on my 2002 Olds Bravada (4.2L engine) as do most Outriders, Envoys etc so I simply removed 2 bolts (13mm) this tool into the open holes on the water pump pulley plugged in and then backed off the 2 bolts while holding the tool, used my giant adjustable wrench on the fan clutch nut, held both in place and used a little muscle strength. freed! I was so happy! But please revise the instructions! It will NOT fit screws larger than 13mm AT ALL! The tool appears to be very high quality, thick steel, so I really don't know how some people say it's bent and all!
