chirping noise on 2001 ford ranger

[tkenned]

i have a chirping noise on my 2001 ford ranger 4.0. i have changed the belt and it went away for about a week, then came back. i changed the idler pulley to no avail. i am leaning towards the tensioner pulley. anyone care to try and confirm my suspicion or make a suggestion

yea, spray some w-d40 at the center of tensioner pulley, the noise should disapper in a few seconds. If it does then your sure this is the problem. The spray is only a temp fix. Then when your ready, you can replace it. Later, Mark.
