i have a 93 4runner chnaging timing belt w/p etc and the pulley for the tensioner is held on by a allen head bolt well to make long story short heli coiled and then bolt broke in head i was wondering if anyone knows what size and thread pich that bolt is i have new bolt on order from toyota but i still need to drill and re-heli coil with right one i think first one did was wrong

 

Not offhand. But, what I usually do is go to O'Reilly, take the bolt with me, and match it up on the bolt/thread size chart they have. The chart may not be able to match up one that big, though. Just have to check.
