Hey y'all:
I've got a squirrel noise coming from a belt or pulley. Goes away when warm. Is there a common culprit I should look at? I mean, is the accessory idler a frequent fail-er? Or should I look to the blower-drive?

waddy'all think?

('03 STR, 120k miles)

 

Sounds like the TSB for Drive Belt Noise, not cheap. In the TSBs or on here elsewhere JTB00045

Might be info here engine sqeaks - Jaguar Forums - Jaguar Enthusiasts Forum

Maybe try a one-off little squirt of water on SC belt to see if noise changes.

 

Swap in a new Gatorback supercharger belt.

 

When you remove the belt, turn the supercharger pulley back and forth and listen for a rattle. If there is, your spring coupler is broken inside the snout. Replacement solid plastic couplers are available, but may be noisey since the spring in the stock coupler supresses the backlash.

 

ok, so taking a cue from JagV8, I dripped a little water on the SC belt while it was squeaking at idle in my driveway. The squeak immediately (but only momentarily) went away. So I'd say he's onto something. (Thanks JagV8!)

I tend to look at things like this as an opportunity to upgrade. It looks like the fix for this problem is several new pulleys and a new belt.

Is this the right time to buy a SC Overdrive pulley setup and install it instead?

What are your thoughts?

 

You're welcome! Thankfully it seems nothing really bad or expensive.

Changing the pulley is for others to suggest (I tend to leave stuff alone).

 

Mcjaguar, it twas me who strongly suggested a new Gatorback belt. The "Squirrels" or high pitch squeeks are pathomenotic for a new belt.

 

I have absolutely no clue what "Pathomenotic" means.... (y'all are very "high-brow" around here...)

BUT: I take from the context that you're suggesting that my problem would likely be solved with a simple new belt. I'll do it. Will this be the same belt I will use when I change-out the supercharger pulley?

 

Doctors like to use big words and send even bigger bills ...

I thinks youse just need a new belt or someone with a supersoaker in the engine compartment.

 

Who carries the paperback? I haven't been able to find it.

 

Sorry dudes. Some things and thoughts come home with me. "Pathomenotic" means: the looks or quality of a symptom is expected to be caused by an already known underlying cause. Mcjaguar, the stock Gatorback belt can be used with a pulley swap.

 

That should have read : who carries the Gatorback.....

Damn smart phone.....

 

LOL! I hadn't a clue to what "paperback" was but went with it anyway. Though off topic; Mcjaguar, pop in a K&N air filter, modded air intake tube, smaller pulley, hi-flow cats and Magnaflow Tru-X center muffler (built-in x-pipe), perform a hard re-set of the ECU (disconnect battery cables and touch them together for 30 seconds), then hang on

 

yeah... so..... grrr....

I ordered my Gatorbacks a week ago, but they won't be here 'til friday.... which is 2 days AFTER I leave for the holiday.... with the car....
so I thought I'd pony-up and do it twice....

I ain't gonna lie: that belt replacement on the STR is a SUM-B!

Anyway.... I'm pissed that I've got the belts off, and now can't find anyone with the S/C belt on-hand. Whooda-thunk?

So while I'm down... I'm browsing looking for a diagram of the serpentine routing. IO can't find one. I tried to follow the procedure to download / Install the JTIS, but it ain't workin' for me.

Can somebody please point me to a simple diagram of the belt routing?

 

You and I are living the same nightmare brother. I picked up the accessory belt at Autozone, but had to order the supercharger (Gates) at O'Reilys. I ordered it on Sat morning and they said they'd have it in by 2pm on Sat. So I pulled the two belts and put the accessory on and waited for the supercharger belt. I called them at 3pm and they said it didn't make it on the truck but that it would be in on the 4pm truck on Sunday. I call them at 4pm on Sunday and they said it got lost "LOST". I asked them when it would be in and they said they had no idea because it was lost and they only had one in the inventory. I ended up having to order one from Carquest. It's supposed to be in tomorrow morning. I cleaned the old one with a scrubby and put it back on. Didn't help....

Here's what I used to do my routing: http://c.fixya.net/fixya20/uploads/Images/141AF75.PNG

 

upon starting mine today there was a squeaky belt for about 10 min, minor squeaking then went away, more embarassing cuz my neighbors were all outside and start my bad *** car and sounds like a hoop D LOL.

Had all belts looked at today they said all look great and it was most likely dealer dropped 6 gallons of armorall in the engine, ... nightmare.

 

Mine was from spilling antifreeze on them.

 

A few diagrams will help!
