Toyota Repair: Toyota timing belt, crank pulley, dowel pin

Question
A timing belt was replaced on the 1994 Toyota Camry. It starts and runs bur lacks the zip and accelleration it used to have. Is it possible they got the belt on one of the gears one cog off? I have years experience with timing chains but not late models with belts and OH cams. How do I check for this without disassembling the engine? Thanks for your help.  Bill

Answer
It's very possible that the timing belt is off, if it's a 4cylinder remove the upper timing cover so the upper gear is visible, rotate the engine until it's at #1 TDC with the crank pulley nark lined up with the O mark on the plastic cover, the cam pulley dowel pin should be pointing up, there is a small hole in the pulley, this hole is lined up with a dimple on the upper cam bearing housing,(use a mirror) if it's off the tensioner needs to be loosened and the belt repositioned. On a V-6 also remove the upper cover, it's basically the same procedure except there are two cam pulleys that need to be aligned correctly, these pulleys have grooves on the edges of the teeth, these grooves line up with the marks on the sheet metal covers, this engine uses an automatic tensioner which has to be removed and it's a little more involved, if this is the case let me know if more help is needed..
