Hey Steve, how anyone wants to interpret stronger is up to them, but no manufacturer will make a statement considering this isn't the correct application

Physically, the two belts are constructed so differently. That Duralast/Dayco belt was SUPER stiff (in a good way). This thing is beefy.

Like Digital Corpus, I cut down my original timing belt jobs down to 50k miles because of the build and 11mm pump, this just puts me back at 60k miles. The idler and tensioner are the only reason I won't risk going longer.

No big price jump between the stock 1Z Gates Belt vs this one at $28. Can't hurt me.

Fwiw, ALH belts are the same width, just longer and with more teeth, of course. Otherwise, the construction of the Dayco belt appears identical.
Also, the CR motors came with Daycos from the factory pretty frequently, those are rated at 120k! Though I will say the Gen 1 CRs are wider, too. The CKRA/gen 2 is back down to about the width of the ALH/1Z/AHU belts, rating remains 120k, though.

no love from the passat this week...

shes been nice to me for a while but now i have that broken door handle i posted yesterday and i had an injector line snap on my way home today... must have had tension on it causing fatigue...

It looked like gallons of diesel sprayed all over my engine bay, so i pressure washed the bay for the first time ever. some of that stuff has never even had a rag accidentally brush the crud off of it. lol.

luckily i had a spare set of lines lying on the shelf so i was back on the road in under an hour, even after finding a second line that had a pinhole rusted in it...

Ya know, maybe if i didnt beat her like a rented mule, she might break down less...

A bit confused about the above statement. I want to AutoZone and Amazon and it lists the Dayco belt as the correct application for our cars. Service interval is still 60k.

Is it because you have an 11mm pump that you're stating this is not the correct application?

Oh really? I thought this was being pulled from the parts bin? If it cross references to our 1z/ahu the question is why has no one (stated online) used it till Digital Corpus? What's that, 20 years? That's why we assumed it to allow for the longer interval *ymmv*
(Wasn't being facetious in my response Todd, those are real question marks. I sound like a dick!)

Lists the particular specific Dayco part number DC identified, or just lists _A_ Dayco belt? I don't think anyone has disputed that Dayco makes a timing belt for the AHU/1Z platform. The one DC identified is for an 11mm stock application but fits the AHU/1Z.

I wouldn't choose any Dayco part number, lol.... 95242. Coincidentally, the Continentals most of us use is TB242. The last 3 digits must mean something, even if it's a cross width.... 24.2mm?

http://forums.tdiclub.com/showpost.p...7&postcount=26

By the pic, it's definitely a beefy belt.

When I Googled the complete part number shown on the belt, the only hits I got were from European sites.

I'm in agreement with Todd on this, the 95242 is correct application for AHU/1Z, at least what I'm seeing here.

Originally, back when this whole uprated belt thing began it was the difference between two Gates belts, not between a Gates belt and a Dayco belt. IDK how the whole discussion moved on to Dayco but it did. I will say though that I have never had a problem with the Dayco product. I can't say though that it's better, even if it is different.

The only reason I asked about longevity was that people have so many times talked about the 'uprated' timing belt as being better with absolutely no evidence to support that one way or another. Nothing from the manufacturer that says so, it's just supposition and it may not be true.

The old adage of repeating something often enough it becomes true comes to mind here.

Not trying to be rude, just trying to bring a little cold water to the discussion.

PS - I did ask Litens once about whether the tensioner needed to be changed at 60k miles when the belt was changed and their response was no. I have run both tensioner and roller for 120k miles with no problems and probably could have gone to 180k truth be known. What I'm saying is there's nothing to suggest that these components need to be changed every time the belt is replaced. Further, there's no evidence that a build or enhanced IP would put any greater strain on either one of these components.Timing belt...perhaps, tensioner and roller...doubt it.

i ve changed tensioner regularly @60k so there are no problems(there), as i dont always have say where certain parts come from(from time to time). seems tho, i have original rollers, havent been changed out since '98. happen to have a couple to swap out(in boxes). havent seen the immediate need to change out. all rollers seem to turn,roll freely.

I did nothing but drive my B4 from Oakland to the South Boise river and back. Never gave a moments trouble, and returned 46 mpg at 65 to 70 mph. Used about 8 oz of oil over the distance of about 1600 miles. That's the longest trip I've taken with it. I realize this post might better be put in the Road Trip forum, but more of the B4 guys will see it here. No oil pan leak anymore either!

the other day i bought a water pump pulley tool. am currently looking for a tool for mk3 water pump pulley. this tool is just a thick piece of metal, its like 1/4" thick, no flimsy handle here, as i ve heard from such 'discount' places like H-F. its tool ?VA 6024? says it is same tool as VAG 1590. seems it ll fit mk2 water pumps, & p/s pumps (pulleys). it ll also fit my mk3 p/s pump, however it wont reach the recessed water pump pulley. what tool do you guys use to get to this pulley? i have the water pump on the v-belt that now goes to p/s unit. tools not bad for $20bucks, over-kill for bolts that get ~20ftlbs of tightness, although as my book value states i increase most factory/book values, to about 23ftlbs-25ftlbs. 'a little' extra insurance, like most fasteners need.

i was, looking at water pump flange, had an idea of taking pliers, or water pump pliers to that flange, although on further inspection of flange it would seem to be 3-sided, wont be able to get a solid bite on it, leverage. is next-on-the-list,-resort. until i find the correct tool.

Have you ever used the SHIFT key to start a sentence?

For the water pump pulley - either use a strap wrench to hold the pulley, or "blip" the bolts loose with an impact gun through the wheel well.

and thanks for the help, think i ll get a good belt that i probably dont have much use for and use a set of vice-grips. the 'bip' thing with a gun would take off bolts, i doubt its much 'help' getting them back on. sounds way too tight. although as i think of it, i happen to have a pretty good craftsman impact with 3 adjustments. the lowest is fairly lo--.

-oop, no CAPS<there we go. (so sarcastic).

i placed an order from napa online, the shipping was slow; on getting package, i was disappointed. i had ordered a water pump, seems this pos is plastic, nfg. they superseded part, perhaps recently, prev pump was metal. no more. pos. no use to me. i had also ordered a gasket, this gasket in the pic appeared to be the metal type, on getting it turns out to be paper. went down to my local napa store, parts guy takes a look, its a metal pic, part# is the same. i ve had some, usually minor problems with napa, and its parts. i ve typically had more problems with other suppliers, and napa prices have been reasonable. not only are their quality of parts declining, they are now giving inaccurate info, and less info on parts. not very happy. then again its the evolution, or declining-evolution most if not all business take since, i-dont-know-when; been younger. worried at how much several cents can make them over how many thousands of (individual) sold items, compounded,added over total inventory and such.

the other week i bought rear wheel bearings, thought i was getting quality parts, that i thought i had ordered. the inners are still fag, slovacia made, good enough quality, for me. the outers about same price, should be same quality ended up being made in japan. not really happy in this change of mfg, quality.
