Pulley problem

Darcimus · 01-14-2013, 02:26 AM

My 06 3.3 is having a problem with the pulleys. A few days ago something squealed, like a loose belt squeal. I put it off, then when I started it up this morning, I heard a clanging noise coming from the engine, and the battery light turned on. I checked everything out and saw that there is a pulley broken off which is rattling around the crankshaft pulley. I figured it was a pulley that had broken off, but all 7 pulleys in the car are present and accounted for. Incidentally, the serpentine belt is way loose, which would be why the car lost power and eventually died.

Am I completely lost or did an 8th pulley magically appear in my engine.

Hi,
My 2006 did the same thing. The crankshaft pulley has a rubber layer between the inside of the pulley and the outer ring. The outer part of the pulley has separated and caused the serpentine belt to go slack and everything the belt drives to stop working. The crankshaft pulley is not too hard to replace if you are somewhat handy. Removing the nut that holds the pulley on is difficult and a large impact wrench is needed, not too bad after that. There are many posts on this site about this, so search and you will find step by step instructions.
Good luck.

Ahhhh, that makes sense. I guess that's the harmonic balancer the guys at he shop were talking about, right?

mayb good time to upgrade to a lighter weight OBX pulley from the Gensis 3.8 V6 Everyone on here says they fit and look better and will add 1+ HP to the wheels. And they "may" be cheapeir to replace (OBX pulley $100, OEM pulley ??). And with no rubber they wont break down the same way the OEM ones do, but i have read one or two stories about the OBX pulley breakin, so i guess nothings perfect

Yes, it is the harmonic balancer.
