Finally going to get the pulley done so might as well do a new belt.

Curious if there is a concensus on the SC belt.

I have always liked gatorbacks but there is no application for the STR.

Looks like either Gates or Dayco.....or should I just get OEM

 

At least get a price on the OEM in case it's OK.

 

Hmm..Interesting story.

Dealer cant sell me OEM belt for 2003 STR because they no longer make that specific belt. The replacement belt is different and will not fit... and so requires changing, bracket, tensioner and pulley....

BTW price for parts only is $ 400.00

At lease the dealer was honest and stated to just get the aftermarket equivilant belt.........

 

fergs03R-

The deal with the factory belt is that they update the idler pulley to being ribbed instead of flat. The new belt is the same size, but ribbed on both sides. You can use it, but I really would recommend doing the complete update if at all possible. It seems like a much better design.

We sell the factory belts for $51.56, and the complete setup with the belt for $233.15

Thanks

That explains why all the belts i came across were double ribbed!! Sounds very reasonable. if i am already in there doing the SC pulley, belt (and also the thermostat)..it would stand to make sense to do these other parts.

Thanks for the info...ill hit up the site.

 

The original SC belt is no longer available from Jaguar - when I replaced my belt last month I did not want to spend the money on the updated design (I understand it was for a cold start noise issue which I have not experienced). I got two belts from ebay, one to put on the car and one to stash away in case I ever needed it:

Seller is 'europeanpartssource', they were good to deal with. No extra shipping charge for ordering more than one belt, even though they actually had to send them from different warehouses - the one from the closer warehouse arrived very quickly.

 

I couldn't find the "Edit Post" button - is there no editing here?

I forgot to say that I have a 2003 STR. Not sure why the fitment table in the auction only lists 2005 STRs.

 

Thanks for the information! My 2005 STR had a small squeak when cold. I was under warranty and mentioned it to the dealer. I was very surprised when they replaced the idler and tensioner along with the belt. It was so minor I didn't think they would replace all those parts. But now I understand why.

Not sure how much smaller the upper pulley is going to be, depending on that you could consider a smaller size then stock like the gates K080514, to be get for $22 or so on the net. These belts are top quality ones, use them myself (think actually Jaguar used these, but have no proof)). For standard pulleys you would require a Gates size K080520, but interestingly that size is not avialable anymore.

For standard pulley sizes you could try Goodyear with partno 4080520 or Dayco with partno 5080520, but I have no experience with these brands.

 

its the Mina 1.5 pully which uses the stock belt....ill check those belts though...thanks to al for the insight !!

 

From tbird6's earlier posting I guess the SC belt must have been either C2C37063 or C2C37055 but I don't know which or whether it was ribbed on both sides. Any idea whether 2-sided ribbed and which part is which?

 

The dealer told me that the 2 sided is only for the new application, and that you need to replace the tensioner, bracket and idler. OEM and aftermarket direct replacement is one sided

 

the ebay link in this post looks to be accurate. i verified this against these 2 places as well which pont to the same belt model number after the vin cutoff code

http://www.captainjaguarscathouse.co...s/C2C26235.jpg

http://content.yudu.com/Library/A1je...lashCheck=true

so looks like thats the one !

 

I think that's after my VIN
(2004 STR)

tbird6 posted the list of parts, including pulleys, etc, but he has a car after the VIN cutoff

 

use goodyear gatorback belts, theyre known to grip over smaller pulleys and eliminate slippage. After I had 2 custom blower pulleys made for my Nissan(smaller blower pulley, and larger idler to comphensate for smaller pulley, still allowing me to use the original setup since its a baztard size) I picked up 1psi on the top, so evidently I did have slippage.

 

Gatorbacks do not come up with an application for the STR...unless there is one so close that it would not make a difference....even the one listed earlier in this post comes up on on goodyears site as not an available product

 

jagv8,

If you need a belt the ebay one should fit - I'm running it on my 2003 STR right now, it works great! As far as I know, C2C26235 is the right part number for all of the old style (one sided) STRs. I don't think they changed anything with the supercharger belt or pulleys until the double sided update.

 

Anyone have the part number for the gator backs for the 3# pulley set up?

 

contact these guys for custom pulleys for everything from wider 8-10-rib, larger idler pulleys to change belt sizes or keep same size belt when going to a smaller blower pulley. underdrive pulleys etc. they do BMW's, Benz etc and custom stuff all day long. He has made pulleys for me in the past and very reasonable.

He does look rather cheap....wonder what he would charge for a crank pulley set up
