Crank pulley??

Magallon0820 · 02-08-2024, 06:12 PM

So when I turn my car on, I get this stretching sound, I popped the hood and it almost looks like the crank shaft pulley,( the big one in the middle) looms like it's wobbly, I am in the process of ordering so I cam replace it looks fairly easy 6 bolts, my question is, if i replace the pulley would it be safe to assume the noise would go away? What causes this to happen is there something else I should be concerned with? ..Car is a 2011 with 135k on it and idk what all had been done to it.

Belt Tensioner and pulleys, and serpentine belt should be inspected as well, replace as necessary.

If you're replacing the harmonic balancer, get the shield that goes behind it to protect against damage from a broken serpentine belt.

Yes a must have especially if you tune! or do alot of traveling like me! There are a few reputable companies that offer the Crankshaft seal guard, or a Crankbolt capture.

Get a good part number, you can call FCP Euro or speak to ECS Tuning, give them your Vin number and they will match exactly the part you need.
