So i just got through installing a new timing belt only to find it jumped out of time...anyways this is no big problem. However my question is in regards to the tensioner itself i was reading this article on installing it when i read that the spring cannot be used to set belt tension; a wrench must be used on the tensioner assembly. When i installed my new belt i installed a new tensioner as well. I also found the wrench, part # T74P–6254–A. So i presume that the spring does not have enough tension itself. could this be why it jumped out of time? please help i need ma truck running. btw its a 2.5l.
