Dayco Belts - Anyone Use 'Em?

Not open for further replies.
I put one on the stang and it started chirping within a week. Took it back and got a gatorback. All is well. I have however used Dayco multiple times over the years with no problems. Kinda like anything else, it's a toss up.
 
Have used Dayco belts and had no problem. But like you have always heard Gates were better, now use Gates, better? Who knowes.

Yes, the poly rib does look a lot like the Gaterback. I like that design and think it works better on small radius pulleys (ie, keeps the ribs from cracking due to tight bending).

I'm going to see if I can find the Gaterback in the local area ... if not, the Dayco looks pretty decent. Probably better than a Nissan OEM belt.
 
I've used both and had no problems. As for the Gatorback design -in some apps it has a noise that is bit like a very subdued supercharger whine. It wasn't loud but it was noticeable on my '99 Ford Escort ZX2 but I soon got used to it.
 
Napa belts are generally Gates brand belts. In the past, I think the Dayco belts weren't as good as they are now. I remember the Dayco belts looking cheap and the printing on them was always off center and the fibers were always random and crooked. They've gotten much better. As a matter of fact, I was surprised to see them on Ferrari as OEM belts. Even their timing belts are Dayco. I replaced a Ferrari 360 timing belt today and I'm telling you, this belt was nice....It was the toughest looking timing belt I've ever seen. Maybe they make special good ones for Ferrari, I don't know, but it also had a "Isoran" logo on it as well. And it said, "Made in Italy."
 
Dayco belts are fine. AutoZone sells a belt that I believe is called "Drive Rite" or something similar. Stay away from that one.
 
I like Gates better. I'm currently using Dayco w/o issue. Gates were not locally available for my app, and I didn't feel like ordering them. Dayco was the only belt I could get w/o ordering them. So far no problems to report in 15,000 miles of service.

I agree. Dayco makes OEM belts and hoses and they are good quality. But I used some aftermarket Dayco belts and hoses and had some really bad experiences. I'm talking a belt shredding in a couple hours use, hoses failing. So I stopped using them and avoid them. I think they have gotten better and they don't seem as cheap now.

I like Gates and Goodyear better, and haven't had a problem with them. I usually prefer OEM belts and a lot of times they don't cost much more than an aftermarket belt. When you buy an aftermarket belt, it is "one-type fits all" materials, spec and construction, and sometimes a close fit but not exact OE length. With an OE belt even if it is a Dayco, you are getting OE spec and fit. I usually use Gates of Goodyear hoses though and they have been good.

Don't the OEM belts follow the "Metric Part No." standard with drive belts? (see link below). I thought they did.

The Metric P/N defines the number of ribs and belt length. So any aftermarket belt should fit like the OEM if the OEMs follow the Metric P/N standard.

So looks like Gates doesn't have a gaterback kind of design with the non-continuous rib design (?).

But what they do is give you a belt length that often times ballparks it. The parts stores don't typically carry every exact length, they just get it maybe close enough. Eh it's usually not an issue and they are pretty close but sometimes you get a tight fit.

The manufacturers of aftermarket belts have application data for the car, and I'm sure the aftermarket belt manufacture's application is very close to the OEM belt. The aftermarket belt might be +/- a few mm of OEM and that should be no problem due to the large adjustable range of the belt tensioner(s). I've never had any issues with belt fitment when using aftermarket belts if using the one the manufacture specifies.

From my past experience with belts, the OEM belt is usually marked with the Metric Part Number, so most OEM belts will match up to aftermarket belts pretty well.

In my case, the OEM Nissan belt is showing alot of cracks in the ribs, and it only has 27K miles on the belt. It is however 2004 vintage, so age must be getting the best of the rubber at this point.
