Recently, I replaced my timing belt, water pump and belt tensioner. Everything looks fine but I noticed something. With the old tensioner (17 years old), the old belt would sit at slightly different position on the pulleys. I mean when I tensioned the old belt with the old tensioner and cranked the engine by hand (to take up belt slack), the belt walked a little more and sat on a different position on the pulleys but with the new belt and new tensioner, the belt walks a little less before sitting in its place. The following picture shows belt location on intake pulley (with the old and new tensioners).
Should the new belt sit at exactly the same position on the pulleys with the new tensioner like the old set up? Is this normal that the new belt walked less than the old one after cranking the engine by hand? New belt tensioner has been installed and tightened properly like the old one.
This is a side by side comparison:
