I am getting a little noise out of the cam pulley area and a friend of mine (good mechanic) says it is just pressed on and there is no bearing on it, any noise you might be hearing is the tensioner or belt. If the pulley is good do not change it, it will make no difference. Here is the cam pulley, although old it is not damaged. So I'm thinking just change the tensioner and belt as it is inexpensive.

your friend - good mechanic - is 100% correct

you don't have to change the entire tensioner -
just replace the pulley on the tensioner

So I just bought this from Gates for $30 and the belt for $10. This will be acceptable?

look at rock auto, i think they make a complete kit, idler, tensioner and belt - if they sell it as a kit then its a good bet you should do the idler and tensioner as tensioners can bind up and not provide the correct tension as the belt stretches, i did mine it was quite reasonably priced

Then what did I buy? Isn't that piece the idler and tensioner? If not what is it lacking?

Oh the idler pulley. Now I see that. Where does it go, it must be under the tensioner? Wait that's on the other side of the motor. Your just confusing me now. One thing at a time.

One drive (cam) pulley, one tensioner pulley, one water pump pulley. What you bought was a good deal but that tensioner (spring arm) pulley is replaceable all by itself.

Yes, the drive pulley is TIGHTLY pressed onto that intake cam extension. Remove and install it correctly or you're in big - big - money repair territory with possibly a ruined intake cam.

Ok now I see. On the part that I bought it is the complete assembly but you can just buy the pulley and put in on the original piece? Either way you have to take the whole assembly out to change just the pulley? BTW you mention 3 pulleys? What am I missing here?

You can leave the tensioner itself in place - don't remove the two long 10mm hex studs that retain it. Simply remove the ?? 13 mm ?? shoulder bolt that retains the pulley, replace the pulley, and set the belt, install the steel safety shroud.

Look at the pic up there ^ ^ ^ with the pulley and bolt removed -

Thanks Sub, that sounds pretty easy with leaving the tensioner in place. I'll just return the whole tensioner assembly and buy just the pulley even thou it is basically the same cost. I paid $30 for the whole Gates assembly, just the pulley it seems is $26 from my limited browsing so far.

Just outside looking at the car, I don't see any way to put a new belt on if you just take the pulley off leaving the assembly in place.

There is no way to change the belt without changing the assembly so buying just the pulley and doing it in place is out. Keeping the whole assembly and changing it out with the new belt.

UPDATE:
So I changed out the whole assembly and the old pulley was shot. It was extremely rough to turn and it felt like it was full of grit. The new one was of course butter smooth turning and all noises went away. Easy to do maybe 15 minutes.

You got lucky and it didn't seize taking out cam pulley. Same day mine came in the mail mine started to lock up. It was trashed. I change them every year or so now, short money I figure.
