5.0L (1979-1995) MustangTechnical discussions on 5.0 Liter Mustangs within. This does not include the 5.0 from the 2011 Mustang GT. That information is in the 2005-1011 section.
installed some underdrive pulleys about a month ago and now i notice that the water pump pulley is wobbling. i took off pulley and put it back on and aligned everything and it seemed to go away. but today its wobbling again...? Could it just be the pulley, or is it the bearings on the pump?
the fan runs off the same pulley, so its forced to wobble with it...make sur eits aligned again, and continue to see if the bolts stay tight after u drive it for a while...
checked the pump shaft and pulley and both were fine. but the fan clutch seemed to be locking up. so i put the fan out of another mustang and it works fine. no more wobble.
