Need to change my belt and want to order the Goodyear Gatorback belt. Been using them for years with great results. (please don't try to convince me otherwise). I went on summitracing.com and they list a different belt for the 03 than they do for an 06. I thought these were the same size? On summit they show part number 4050515 for my car but I read on here that someone purchased it and it was the wrong size. Then I searched for an 03 and they had part number GTR-4060705. Anyone know which one is the correct one?

 

I was told it was, I have one in my garage but havent installed it yet, I'll try to install it in the morning. The one I got was for a 03, Goodyear 406075 from Autozone.

Thread where I asked about it a few days ago. Note on the last page someone said Advance lists 4060705 part number for IX's.

There are only 2 belts for the VIII's and IX's.

With AC - MN158794
&
Without AC - MN158795

 

Thanks for the confirmation Russell!

 

Sounds good, I will go with the 4060705 for my IX.

 

I installed my Goodyear 406075 on my IX MR the other day. Perfect fit, installed with ease.

 

i know this is an old thread, but just for correction, the part number is 4060705 and not 406075

 

The OEM accessory belt on my '03 was looking a bit sad by 45K so I replaced it with one from advance auto. The advance auto belt ran to 120K, still looked good but got replaced anyway at timing belt time. With advance its a mixed bag but their accessory belt appears to be better than OEM.

 

120K damn, that's a lot of mileage for an accessory belt,
i've ordered the goodyear gatorback, very curious to see what the "quiet" feature is all about and if it works or not.

 

could u be having the advance auto belt part number? might come in handy someday

 

You misread or I wasn't clear in what I wrote. The belt didn't go 120,000 miles. It went on at 45K and rode to 120K or 75,000 miles. I don't recommend this but since the replacement belt was showing little wear I decided to stretch things a little and synchronize the timing and accessory belt changes at the 60 K mile interval.

The belt bought at Advance Auto is a Dayco and carries two numbers: 6PK1790 & 5060705.

 

yeah, looks like I misread, thanks for the pns
