i have a squeak i cant find. Changed belt pulleys water pump still squeaks when it warms up

Hello, What year is your Taurus? Thanks, CarGrrl

possibly the idler pulley bearing or alternator bearing. be very careful and listen with a long screwdriver.

sometimes its nothing....some cars just squeak for no reason...it doesnt mean there is something wrong w/ ur car

if its a squeal similar to a belt noise and this is a 3.0 its a cam synchronizer. replace both the synchro and sensor, but i would recomend having a trained tech do the repair, alignment tools are needed for this replacement. improper alignment can lead to altered timing, driveability issues, and possible parts damage. parts are about 250-300bucks for both

Cam shaft position bearing
