Belt Tensioner Pulley
I have a 2005 C6 had it in the dealership for some belt changes and the dealership says I have a belt Tensioner pully that has a lot of wear and will need to be changed soon. They told me the part was about $80 but the labor would be 6hrs. Is that true??

Ask them whats worn on a Belt tensioner pulley.
Pulley is steel it's not going to wear against a rubber belt.
Spring tension bad?? Probably not. The tensioner has marks on it so you know when belt is exceeding its stretch.
Bearing going bad? maybe but you're going to hear that making noise.
IMHO They're full of it and want your money.
BTW the belt tensioner tool is a 15mm wrench.

Usually it's the bearing on a tensioner pulley that goes bad. With many of them, you can replace just the pulley wheel/bearing and not the entire arm also. Six hours is ridiculous. One hour maybe.

One bolt to remove the tensioner pulley. The pulley is not a special item. It is usually in stock at Auto Zone or O Reilly. Like. AZ Motörhead said, there is not special tool. A 15mm open end wrench releases the tension and the belt slides right off. Belt removal take less than a minute. Make note of the routing so you can put it back on properly.

Does anyone else have this "feeling" that the dealer/service is talking about the harmonic balancer, based on the number of hours quoted? Or, got the two confused on number of hours to replace?
Just came across the other thread by OP; looks a bit confused as to what is being stated as the problem.

That IS funny, Chris. I'll go either way on this one.

To add on the pulley bearings, most of the time if you catch it soon enough, the bearing is not bad, but just dry instead (read not enough grease used when the bearings where first assemblies).
You just need to pull the pulley off to get to the bearings, and pull the bearing seals covers off, clean the bearing and re-grease the bearings. pop the seal covers back on, and put the pulley back on.

In short, if bearing grease is dried - you have a bad bearing. If it is not that bad, than, why fool with it!
Physical attribute on sealed bearing cover consist of a precise engineered fit to retain lubs, at the same time, prevent entry of contamination for the life of bearing unit and if removed after initial install, seal is violated and will never be the same.
Consider the efforts of the above, a replacement quality bearing can be had for under $10 from various reputable sits - if indeed, culprit is the bearing.
On my Katech Tensioner, I changed out its new Chinese bearing with an American made, before install for under $10:

Pulley is steel it's not going to wear against a rubber belt. - most modern GM belt tensioner pulley is molded plastic with a press fit sealed bearing.
Spring tension bad?? Probably not. The tensioner has marks on it so you know when belt is exceeding its stretch. - having correct spring tension is only a small part on the equation, due to design parameter, spring tensioner assembly provides a poor fit along with wobble on its best day and its sloppy eccentric runout have a direct effect, added onto the Harmonic Damper's runout. Contrary to believe, modern serpentine belt stretches little over its useful life. OEM type belt tensioner is simply a mean to simplify maintenance for most people!
