Serpentine Belt Tensioner

So, I bring my 2006 PF to the dealership for the first time since buying it (i got it about 6 weeks ago). It was due for an oil change, and I found out that it was eligiable for a ECM Relay replacement under a Nissan recall (whatever a ECM relay is, I really don't know

).
Anyhow, I opted for their 21 point "Winter Checkup" inspection as well. I mentioned to them them I hear a whining noise at startup. They look into it. During this inspection, they determined that the noise was coming from the serpentine belt. Belt condition itself is ok, but is quite loose. Auto tensioner is weak, and they recommend replacing the belt auto tensioner. Also, they recommend that if they're replacing the auto tensioner, they may as well replace the belt itself too.
Has anyone ever done this repair themselves, or see it as a "must-do" repair? Parts and labour for this repair is quoted at about $230 without a new belt.
Any feedback appreciated.

It's an exceedingly easy job if you're at all handy with tools. There's a socket on the tensioner that you just put a 3/8" socket driver into to get a handle and leverage on it to lean it over and slip the belt off, and then just one more bolt to replace the tensioner. You may need to remove some of the intake tubing parts to get access, but certainly not the radiator fan as specified in the ESM on page 15 here:

Over on
http://www.courtesyparts.com the tensioner costs about $50, and the belt another $25'ish.

replace the belt along with the new tensioner
$230 (even if it included a new belt) is very excessive
..........typical for a dealership

if your belt is aftermarket, replace it with the oem nissan belt. theres been some issues with aftermarket belts and the grooves on them making noise on the pulleys, even if new

Thanks for the feedback. I got a quote from my neighborhood mechanic (used him for years with all my previous cars) and he quoted me WAY less for parts and labor than the dealership (no surprise). But, he quoted me $90.11 for a replacement belt (OEM Nissan). Does that sound right?
May get it done next week.

way too high...you can order them from Nisson for $25 or less. I put a NAPA belt on mine with no problems.

I got my belt from the dealer for around 20-25 dollars I believe

I dunno. My local mechanic says he'd charge me 0.5-0.75 hr shop rate ($90/hr). May be worth it for him to do it.
Plus, it's cold out and I don't have a heated garage!

Hey Gear,
Are you positive its a belt noise? I have a whining noise that comes from my fan clutch when the temps drop to where they are right now. It does it one startup, and goes away when you rev the engine.
I originally took it in to the dealer (it was right after we bought it, it had about 10k kms of warranty left on it) and they did the belt and tensioner (unfortunately not covered by said warranty), about $300 if I recall. Didn't fix the problem.
After some run around, they identified it as the fan clutch, and the tech actually said its a known issue. His comment was that even a new one may start doing this after a short time, and not to worry about it.
That was 5 yrs ago, and its been fine since then.
What end of town are you in. I could give it a listen if you like. For free...

Just throwing in my .02 cents. Replacing the belt is very easy, you can do it yourself in less than 5 minutes and the belt is only $24.00 I think from the dealership and I verified it at courtesy parts.
Please do not pay that amt to have a belt done, even if they are replacing the tensioner, you could do that too.

Hey disallow, thanks for the offer. I'm in St. Vital. If that location's convenient, PM me your number and maybe we'll set it up.
The more you guys say how easy it is to replace the belt/tensioner, the more I'm thinking that I'll do it! We'll see.
The whining is less and less now (maybe due to a rather balmy by Winnipeg standards weekend).
