The alternator o-ring replacement is around a 6 to 8 hour repair. The motor mount on the driver side must be removed, the alternator removed, the alternator bracket must be removed, power steering must be dropped, & the radiator cooling fan needs to be removed. Once you get to the o-ring, put some ATV back around the o-ring, or you might get to replace it again!

This job ain't fun!
