Serpintine belt

Just letting eveyrone know the Goodyear Gatorback belt that lists for the 03 with a/c single alt. is too long and will make an awful racket at idle. Dayco and Gates list a shorter one. I will putting on the shorter one on Monday?.. we will see how it turns out. [img]/ubbthreads/images/graemlins/confused.gif[/img]

Re: Serpintine belt

That belt isn't one I'd like to do twice for a part number foul up. Good info.

Re: Serpintine belt

Speakin of how difficult it is to change, I was charged 243.00 to do it last time, and yes if I had used the FoMoCo belt I wouldn't be asking this again.

Any easy tips, tricks to change it with the fan shroud removed, or is it possible but laborious to do the hard way?.


The good thing is I can return the other belt though.

"My Grandpa did the hard way so it must be the right way" [img]/ubbthreads/images/graemlins/smile.gif[/img] just joking

A guy told me once not to think outside the box but to think intelligently while your in it.


Any help would be really appreciated.

Thanks for being so quick, and the advice I really, really appreciate it.

Re: Serpintine belt...........Thank you.

GDY 4081265 too long

Dayco Poly cog Gold label, 5081260 fits and is somewhat shorter than the Goodyear.

Anyways just trying to prevent someone from going the the hassle.

Re: Serpintine belt...........Thank you.

I normally just pull up hard on the belt and slip it off the alternator. Put on the new belt and when I pull up on the belt I have a friend pop it back on the pulley. A mechanics glove helps get a good grip.

Re: Serpintine belt.....

Drove the truck about 50 miles today, Dayco belt is tighter and it does howl, but very slightly not enough to worry about. The Goodyear was very annoying.

I think the howling is due to the cross cut pieces, the Ford belt doesn't have that hatching and it never howled.

Just an FYI - The proper Goodyear belt # is 4081258.

That is 125.8 inches instead of the 126.5 inch long belt of the previous GDY part number post.

I bet (hope) that is the difference since I just bought the Goodyear belt.

Remove the belt tensioner, that will give you room - but it is still tedious.

Procedure:
Reach over from the passenger side with your left arm and grab the belt just above the tensioner and pull hard enough to be able to flip up the spring loaded locking tab on the underside of the tensioner up (This takes some muscle, but not too bad). OR ... you can use a 1/2" drive torque wrench, or the proper OEM tool to turn the tensioner.

You can use a long flat head screw driver to flip it up with your right arm and lock it in place, but better to have a partner!! Now you have enough slack to pop the belt off the top side of the alternator pulley. Pop the belt off the rest of the pulleys and then you have to crawl under the truck and remove the belt from the crankshaft pulley folding it sideways and forward so you can lift it up and out from the top side of the truck (Same side as tensioner). You have to fold it sideways to get enough clearance to slip it past the fan shroud. After you get the belt off, inspect all the pulleys for noise, play and roughness. I replaced both of the tensioner pulley bearings (6203-2RS) for about $10. I think the water pump and idler pulley bearings are also the same bearing. The bearings are easily pressed out, just make sure you press them back out of the tapered side or you will expand bearing retaining hole making the pulley useless (Side that has the rounded edges where the bearing sits). Getting the serpentine belt back on is a little more tricky. The upper side of the radiator support on my 06 has a diagram that helped. Insert the belt smooth side up, beginning from the right side of the truck. Pull a loop over the tensioner pulley. Then go over the AC compressor. Go around the idler closest to you and then over the alternator. Hardest part is probably getting the belt around the smooth side tensioner pulley and a/c compressor pulley. Once everything is lined up properly (Triple check this or you will destroy the belt), yank HARD again on the belt in the same place you did to release the tension. This time you can use both hands or your right hand to do it if you want. The tensioner clip will pop back out of place automatically. DON'T PRY the clip back down, you WILL break or damage the clip - it is CHEAPLY made!

Thanks alot Mark, I will give it a shot tomorrow. I have a 081265 Gates belt from NAPA. My OEM belt has 94,000 miles on it with no issues but I want to change it as I am going on a vacation towing my travel trailer here real soon. This why I like forums, always somebody willing to help!
