This is my Vehicle VIN#KM8JM12BX5U121871

So, I had a lot of grinding noise coming from my engine. Upon further inspection I realized it was the A/C compressor pulley and the idler pulley causing the noise. So, I’m ordering a new compressor and new idler. While I was down there, I noticed a very slight wobble from the harmonic/crankshaft pulley. It’s not bad or making much noise but was considering since I’m already here perhaps I should just do ahead and replace it. Anyways I’m struggling to find the procedure for this including tightening torque. I have an impact to remove it but how do I tighten it up without it just spinning? Note that this vehicle has 3 belts. If you have access to the manual and can show me the procedure for this, I would be very grateful. Also, any tips you recommend. Thank you

Holding the balancer can be tricky, in the shop we used a large impact which did the job, but if you need to torque the bolt you will need to remove the starter and install a special tool to hold the flywheel.

Crankshaft Pulley
Crankshaft pulley bolt .................... 170 - 180Nm (1700 - 1800 kgf-cm, 125 - 133 ft. lbs.)

Here is one for 52.00 on Amazon:

Or you can use this tool to help hold the balancer itself:
