Looking to buy one asap. Stupid shoddy GM design has already rounded off...

 

if the corner is rounded on your tensioner then hammer down a 14mm instead of a 15 an then jus pull it off...its what i did an it came off easily when i was done

 

Thanks for the tip. How hard would it be to remove the whole thing and machine it down?
Can I still use this tool if it gets worse?

 

theres really no need to machine it down...do you mean so you can make it a square again?...wat would be the point?....the 15mm wrench is loose anyway an when you hammer down a 14mm on it, it makes it easier than the 15 cuz its tight an theres no play to come off when your pushing the tensioner down

 

I took my dremel and grinded down one side until a 14mm fit on there snugly. working good so far.
