asked by on

Can I change my pulley without having to change the harmonic balancer?

My car has an automatic transmission.

Hello, thanks for writing in. For this particular vehicle it appears that the pulley and harmonic balancer are integrated into one unit. That means replacing either would be to replace both, as they are one part. If you would like help with the replacement, consider having an expert automotive technician from YourMechanic come to your home or office to perform the replacement for you.
