More info please. What are the conditions when the squeel happens? For example, my engine squeels every so often (though happening more often as of late) at 2500 rpms. Thinking idler pully but been to lazy to tear it apart and check. Give us a little more info as to what is happening in order to help with suggestions.
So, first question, how did you set your belt tension ? Osmosis, best guess, twist and guess, looks good, push with your thumb till your under fingernail gets to the correct color ? or did you do it correctly with a $14 KRIKIT II tension gauge from NAPA to get a used belt to 170lbs or a new belt to 190lbs
The first four methods generally get you to the 90-120lb ball park, thats for real, you need 170 on a used belt [one run more then 15 min] and 190 for a new belt [one run less than 15 min].
I cannot seem to find the engine squeal that I have. I have replaced the tensioner pully, idler pully, and the belt. Seems to be coming from the drivers side. Any ideas? Thanks, Scooby
