I have a 1995 ford f-150 I just bought it and the belt was shot so I replaced it. I started the truck and the belt started to walk itself off of the crankshaft pulley. At first I thought it was the tensioner because the belt didn't seem very tight. I went and bought a new tensioner and installed it and the belt is still starting to come off the crankshaft pulley I'm so confused

Sight down the belt where it goes around all of the pulleys. The edge of the belt must be perfectly in line where ever you look. If you see the belt peeking out 1/8" from where it goes around the other pulleys, that is the place to check. I hope this drawing will help. The three pulleys on the left are some of what you would see from the front of the engine. Notice the red part of the belt. Those three pulleys on the right are what you would see looking down from on top. The red part peeking out on the center pulley is what you do not want to see. If you see that on any pulley, it is tipped and causing the belt to walk off-center.
