Both of our cars, until today, sported the original serpentine belts. The Acura had 78k miles on its belt and the Honda had 56k on its belt. I had tried a Goodyear Gatorback belt on the Acura before, but something about that belt didn't agree with the belt drive system because when the A/C compressor was engaged, the tensioner would rattle back and forth like a can of spray paint. So I put the OEM belt back on, and figured I'd get a new OEM belt one of these days.

An Advance Auto Parts mailer came yesterday with a 20% off coupon for "a Dayco belt, tensioner, pulley, etc". It said "a" as in singular, but I told them that if they'd do 20% off two belts, I'd buy two, one for each vehicle. That's how it was programmed in the system I guess, because I got 20% my total purchase of two belts. Nice.

So the Acura's got a new one, which doesn't cause the tensioner to go into a tizzy, and the Honda has one, though it fought the whole time against it. I had to remove the right front wheel and even then it took 30 minutes. The Acura's belt slips on and off in about 5.

Anyway, good service so far from Dayco's new Poly-W belts. Time will tell, obviously, if durability is up to OEM standards, but they run smooth and quiet, like a belt should.
 
i got a w belt on an 06 liberty since 2010 and i have nothing but good things to say about it.

when you upgrade to the w belt it is made with edpm rubber compund, and is much superior to the cheaper rubbers (nitril?) in the lower priced belts. mike
 
Talking about belt ! My 138k miles E430 has original serpentine belt, it shows no cracks and no sign of pending failure, I don't know if I should replace it any time soon. May be buy a replacement belt and put it on when it shows some cracks.

What was wrong with the old belts in your cars? How did you know they needed to be replaced? When it gets cold or after a lot of rain, I think my serpentine belt squeals for a few minutes after startup. I've been on the fence about replacing it. Because it still looks like it's in good condition.
 
The Acura's belt had close to 80k miles on it, and that's the vehicle my wife and kids ride in, so I wanted to get a fresh belt on it. The Honda's engine has a very slight "whistle" or sing to it that matches engine speed. It sounds like a very faint pulley bearing whine. I thought that replacing the belt might be a good first step. The belt didn't fix it, so I'll have the dealer look at it under warranty.
 
Do you have the part # for the Dayco W-belt for the CRV?

I am getting a part # of 5070690, but I am not sure if that is the W one.

Thanks.
 
Thanks. I need to replace the belts on both of our cars. The Honda is OK for now. Mazda should probably be changed soon.
