Yes, all cars do. It is the crankshaft pulley assembly...the biggest pulley, typically, at the very bottom of the engine.
The harmonic balancer is located on the front of the crankshaft
Remove the big center bolt that holds the harmonic balancer in place. If you have a complete hub puller assembly, it should screw into threaded holes. You'll need to work something out to protect the crankshaft threads when you tighten down the puller, just be aware that you don't want to destroy the crankshaft by messing up the threads. Tighten the puller and it should remove the harmonic balancer for you.
Harmonic balancers are located on the crankshaft, usually the belt side of the engine.
Disconnect the battery and remove the fan assembly and crankshaft belts. Remove the center bolt from the pulley and use a crankshaft pulley remover to pull off the pulley. You can usually borrow one from an auto parts store.
The harmonic balancer is attached to the crankshaft using a Woodruff key or a square key and center bolt.
On any motor, the harmonic balancer is on the front of the crankshaft. It is what the pulley is bolted to.
The crankshaft damper is behind the crankshaft pulley.
To change the harmonic balancer on a 1999 Pontiac Montana, first, disconnect the battery and remove any obstructions, such as the serpentine belt and crankshaft pulley. Use a harmonic balancer puller to carefully detach the old balancer from the crankshaft. Once removed, clean the crankshaft and install the new harmonic balancer, ensuring it is properly aligned. Finally, reassemble any removed components and reconnect the battery.
