Is it a good Idea to replace crankshaft sensor and seal when replacing Harmonic Balancer?

Hi,

The crankshaft is at the bottom of the engine. Also, to answer your question, if you don't have an oil leak at the crankshaft front seal, I would leave it alone.

Also, a crankshaft position sensor can cause starting issues. Take a look at this link and let me know if it seems to mirror what you experience:

If you feel that could be the issue, the sensor is located beside the crankshaft pulley (harmonic balancer). Here is a link that explains in general how one is replaced:

If you look at the pics below, they are the directions specific to your vehicle.

Let me know if this helps or if you have other questions. Also, is the harmonic balancer damaged? I ask because it isn't a common problem.

Let me know.

Take care,

Joe

See pics below. The last pic shows the harmonic balancer and crankshaft sensor. I highlighted the sensor and where it will be found, and I circled the balancer.
