i replaced the alternator, belt tensioner assembly, and the belt the other day. the only thing that made it stop sqeaking is the belt, so i took the rest of the stuff back and its been fine for a few days, now its sqeaking again.


any help is apreciated

 

Does the belt seem tight enough? Tensioners do get tired with time, and a new belt may have been a temporary fix until its 'new' wore off.

Recommend not to use any belt dressing, especially on a new belt. Results are typically only temporary.

Are the pulleys correctly aligned? Had an instance where the P/S pump was replaced and the pulley was not pressed on properly, resulting in a slight jag in the belt path.

Also, are the pulleys clean? Dirt and rust may contribute to squeaking.

Have you tried to isolate the sound with either a mechanics stethoscope or a sounding rod (I use an 18" socket extension)?

 

ok guys im trying multiple things, replacing water pump and water pump pulley and also trying a gatorback belt. ill let you know which one fixes it, i wont trust anyhting though until one week from install if its still not sqeaking.

 

If you still get any noise after you replace the w/p and belt,i would check the idler pulley and check the air pump pulley while the belt is off for any play or excessive drag or resistance.

 

well i bought a gatorback belt, and a water pump.. once again i put the belt on and its fixed, but this time i put 75 miles on it between yesterday and today, previous belts its was a few miles and they were sqeaking again..

anyway well see how this works and if i need to replace the pump i have one ready to go... thanks for the help ill update this if i have to replace the pump as well.

 

ok as an update im at 200 miles now on this gatorback belt with flawless results, ill be hanging onto the water pump for almost another week then its going back. in the end it seems that i just needed a high quality belt. thanks guys

 

I had the same problem....My belt was chirping, so quick trip to AutoZone for a new one...A/Z belt chirped as well...Returned it for refund, and obtained a different brand belt from CarQuest...C/Q belt chirped also...Returned it for refund and obtained OEM belt from Ford... Ford belt chirped also, got a refund and then bought a "GATOR" and it has been quite as a mouse for over a year now.

 

I like the gatorback belts... Never had any combacks with them.
