What is causing my 2004 Toyota Tacoma to "squeal"?

Asked by Oct 17, 2015 at 09:05 PM about the 2004 Toyota Tacoma

Question type: Maintenance & Repair

My engine squeals sometimes when starting and sometimes a few minutes
after it has been running.  It goes away after the engine warms up (usually
just a few seconds of squealing).  I have disconnected the idler pulley and
air conditioning pump, installed new belts, replaced the water pump and
serpentine belt and the bearings they run on.  None of these have solved
the problem.  Please HELP!!!  I need some new ideas of what to do next.

Did you check the new belts for evidence of slipping? Remove the belt ,,, get some 100 grit paper and get the shinny glaze off the pulleys make sure no grit gets into anything .. then clean it and put the belt back on

Tom, I want to thank you for your response. Oddly enough, my last name is Harmon also and my brother's name is Tom! -- (You don't happen to live in Missouri, do you?!!!) Thanks again and I will put your suggestion to the test tomorrow! Leon

No one there .. I think they hung the last one back in the 30's and all the others ran away to Maryland (just joking/

Check the alternator bearing. It may be helpful to isolate the noise to the belt(s) by starting the engine and running it briefly with the belts removed from the engine. If the noise is still there it is not the belts.
