Squeaking under hood

when does it do it?

all-in-1 fan belt & pulley replaced 2/22. Drove it for about 2 hrs 2/23 and no noise. Started it up last night and squeaking started then...when accelerates its louder but squeaking continues as driving. thanks.

does it do it while sitting and idling? is it a chirpy sound or a steady squeal? you could try using a wand/hose to your ear to locate sound while someone revs motor with hood open. do you have air conditioning? the idle bearings on the pump can get noisy/squeaky.

It appears that there was too much lubricant on the belt. When used soap to remove some lubricant it is now no longer squeaking. Thank you for your time. I really appreciate it. And have a great weekend!
