on the harmonic balancer.
It is located on the harmonic balancer.
To remove the harmonic balancer from a 1995 Pontiac Bonneville, first disconnect the negative battery cable and drain the engine coolant. Remove the drive belts, then use a harmonic balancer puller to detach the balancer from the crankshaft. To install the new harmonic balancer, ensure it's properly aligned, then press it onto the crankshaft and reassemble all components in reverse order. Finally, reconnect the battery and refill the coolant.
The threads on a Pontiac Transport harmonic balancer are typically left-handed. This means that the bolt used to secure the harmonic balancer is tightened by turning it counterclockwise. It's important to verify specific model details, as variations may exist, but left-handed threads are common for this application.
The most common reason for the harmonic balancer breaking on a 1994 Pontiac Bonneville SSEI is the inner and outer mass is breaking the balancer down. This happens because your engine is running rough or too high of RPM's.
