Ordered a water pump this morning and would like to change my belts when I swap it out. I'm curious about which belt to order. From what I understand, that is determined by the type of alternator that I have, is this correct or is there another way to determine which sizes I need?

 

I'm looking to pick up Gatorback belts as well as replacement tensioners...

The belts usually have markings on them e.g. 4060922 (which reads: 6-rib, 92.2") but it can be annoying to read them off serpentine belts. I noticed the Gatorbacks were much quieter than the factory belts. IIRC Amazon had decent prices on belts and pulleys (but that probably varies by model).

 

I'm sure someone will chime in with what model #s you need.

Use Gates or Goodyear Gatorback both are premium quality and quiet. You can, as mentioned, get the old belt #. Look at your alternator, you'll see the amp size marked on it. More than likely you have the smaller size of the two. Check parts prices both locally and online. I can buy belts, pulleys and tensioners for the same or less than Rockauto or Amazon. Sometimes Amazon may have the lower prices, but their prices fluctuate lately

Dayco also sells a belt that is similiar to the Gatorback.....I bought one years ago after discovering that it was hard to come by the Goodyear belts locally. It is still on my truck and has performed well. They can be bought at Advance Auto Parts.

 

After doing a little research I see that Dayco no longer manufactures the Poly Cog belt. It was replaced with the Poly Rib belt. I found this info from another forum:

 

"I'm the Director of Marketing for Dayco Products in North America. A few years ago we changed our national brand serpentine belt construction from Poly Cog to Poly Rib "W" belts. Why? Today's belt are now made with EPDM rubber to last 100K miles. Today's OE belt drives are not created equal and some can be real demanding. Since these EPDM belts have stiffer charactoristics, they are prone to make noise with slight misalignments. Dayco engineers created the "W" Rib to allow the stiff rib to conform to slight misalignments and not make noise. Every manufacturer was forced to make this change to EPDM and everyone faced noise issues. The change from Poly Cog to Poly Rib was a running change as inventory ran out. This started in 2007 so lots are gone. AutoZone and Advance may still have your number."

 

Now you can see how long I've had mine installed.....lol

Thanks for the help, guys.

 

I had to go by the number on the old belt as I couldn't find the amp size marked on my alternator.

Just got done replacing both my belts today with new Gates belts....I was told from the dealer earlier today while getting my oil changed that I needed to replace my ac belt..I asked him how much...his reply 130.00 to replace an ac belt I laughed and told him I would do it myself for that price. Just an fyi.... there was only one little crack(and I mean little) on my ac belt and not one crack on my main belt and I just turned over 93k...not bad wear I would say for a 2007.

Bowtie for Life !!!

      Oil Consumption

      By Chuck FB · Posted

      Ok that confirms the extra quart theme they are still going with which must mean they have noted some initial use more so then some engines and probably the bigger factor in all of this probably isn't the engine so much as its the insane distance or OLM that lulls a lot of the driving public into driving their new vehicle off the lot and not even doing one short interval oil change because the manufacturer doesn't say different and if the dealer follows that logic as well. Selling the rarely needing to be serviced concept seems to go over well with the public that wants to get away with as little as possible for dollars spent on the vehicles maintenance and I bet there are 3.0 engines just like other vehicles out there that never have their oil checked by the owner which goes back to why they probably felt the need to add that extra quart to avoid a costly theme.    Speaking of cutting filters open, it was probably over two years ago now that a youtuber who buys vehicles to do longer term reviews and pulls a fifth wheel through the mountains of Colorado on summer trips and that becomes part of the testing. Anyway he had a GM HD with the 6.6 gas and a Ford 250 with the 7.3 gas at the same time and of no surprise the Ford had more power etc but somewhere along the way in the few thousand miles he put on the truck, he changed the oil and was seeing glitter and cut open the filter and yeah, things were not looking spectacular. The truck about that time or soon after seemed down on power compared to what it had been and then threw some engine code, I expect the cam/lifters were failing and so he brought the truck back to the dealer and made some deal to get out of it as he knew it would sit for months waiting on a new engine as they were so backlogged at the time. He kept the GM for some time after that using it exclusively until he sold it after buying his next vehicle to do a review on. Definitely the filter can tell a story when things are starting to go sideways, but it would be a sickening feeling to cut it open and be faced with an ugly mess like that and be running a magnet through the pleats and the oil on the dirty side of the filter and see all the fines sticking to the magnet.    The dealer may have some ideas based on experience as to where that coolant smell is coming from, I would imagine if they can't find it but its smelling they would put dye in it to they could give it a run cycle and use the black light to see where it pops up, if its a hose connection, water pump, rad or even a head gasket etc.

      Oil Consumption

      By KARNUT · Posted

      It’s at the point of amusement. I’m retired I have time. It’s fun seeing people try to convince me I’m using oil. I’m buying oil at the prescribed time. It gets drained and new goes in. Do I add in between, no. My oil doesn’t even get dirty in 5k miles. I don’t even see any drop on the stick. I check in the same place. All is well.
