I have a 1992 2 wheel drive Ford F150 with the 302 motor in it. I have changed the water pump, tensioner, belt, smog pump, and alternator. After each time i installed the new parts the loud squeal would go away for about a day and then it starts squealing very loudly again. I do not know what else to do. I took it to a mechanic today and he just installed a new belt and said it was fixed, well it has started again. It is very loud when the rpms climb higher and isnt as loud sitting in idle. What is more likely to be now? Power steering? A/C bearing? or fan clutch?

Thank you,

With all that done and still a noise you will probably need to listen with a stethoscope for which item is the culprit.

Make sure belt it tight enough even with all that new stuff it could be a bit long for self tensioning.

Note: A/C clutch bearing can't make noise if compressor is engaged as it's still during operation relative to the speed,
