I've noticed a squeel at WOT between 1-2 shifts from my serpentine belt (I assume). Is there any problem with this happening? Should I upgrade to a Gatorback belt? How tough is it to change out belts...any pics...Thanks in advance.

 

My stock belt slipped so I changed it out to a gatorback. It took about 10 minutes.

 

You might want to check the belt tensioner, it may be getting weak.

 

Without him saying how old a truck he has it's kind of hard to judge exactly what we need to tell him.

 

the belt is extremely easy to change, all you need to do is draw a quick diagram of the routing before you take it off, and them put the new one back on the same way. Either a Gator or a Daypro belt, and like someone already said, check your tensioner, may be time to replace it too

 

Sorry, I've got an 05 5.4L...Thanks

Is there any problem with the occasional slippage at WOT??

 

Honestly, I only noticed the slippage at startup on rainy or very humid days, and then after I got the Edge programmer I noticed the slippage at WOT shifts. Then I decided to research here and decided to get the gatorback because that seemed like the common cure. I examined my belt after I got it off and it was contaminated where the grooves were, like the pulleys were driving road grime in there and packing it tight. The goodyear belt has a better groove design and I think that wouldn't happen. I think the belt contamination assists in the slipping.

 

Factory belts can do this. They slip because of the fast engine speed changes at shift points. The gatorback has better "traction" and will almost certainly solve the problem. Cheap too..... then keep the stocker around for long trips as insurance, cuz if you lose the serpentine for some reason, you're pretty much d.o.a.

 

Thanks a lot, I'm gonna get me a Gatorback..Chow
