I have a 98 camaro, z28 model. I have replaced the belts, all new belts and new idler pulley, new belt tensioner, and I have tried wd40, then cleaned everything and used a belt conditioner. It still squeaks loudly, but not at start up or when it's idling. Only when I press on the gas. Gets very loud; louder than the v8 engine itself. I have driven for weeks just to see if it was just the fact that it was a new belt; no luck. Please help

DOES IT DO IT IN PARK---GIVING IT THROTTLE?

IF SO, REMOVE THE BELT AND SEE IF IT IS STILL DOING IT. DO NOT RUN IT WITHOUT THE BELT NO MORE THAN A MINUTE !

RETURN WITH RESULTS

It will do it in park from a cold start, but if it's warmed up it won't. Also from a cold start, shift into drive and it stops until I touch the gas.

It does not squeak when the belt is removed.

I DID NOT GET EMAIL NOTIFIED.I HAPPENED BACK ONTO YOU IN OUR INTERFACE

SOUNDS LIKE A PULLEY ISSUE OR EVEN A BADLY WORN BELTMAYBE IT JUST AIN'T-A-GRIPPIN' NO MORECOMPARE YOUR BELT TO A NEW ONE. IF IT'S BEEN LIKE FOREVER, BREAK DOWN, GO IN THE BACK YARD AND DIG UP ONE OF THOSE JARS."SPLURGE A LITTLE". TREAT YOUR CAR TO A NEW ONE!

WHILE THE BELT IS OFF----ENGINE IS OFF---SPIN THE PULLEYS---YOU ARE LOOKING FOR ANYTHING THAT DOES NOT TURN SMOOTHLY

TRY THIS WITH A HELPER

RUN NEXT DOOR, AND IN AN INCONSPICUOUS PLACE, CHOP OUT A 2-3 FOOT SECTION OF YOUR NEIGHBOR'S GARDEN HOSE. OR JUST USE A SIMILAR PIECE OF HEATER HOSE

KEEP IN MIND THERE ARE EVIL FORCES UNDER YOUR HOOD THAT WILL PUT A-HURTIN' ON YOU IN A SPLIT SECOND---WHILE IT'S RUNNING---AND YOU ARE NOT BEING CAREFUL!

SHOVE ONE END INTO ONE OF YOUR AUDITORY PORTS (YOUR EAR) ---USE THE OTHER END AS A "CJ MEDEVAC-O-MATIC" STETHOSCOPEGET IT NEAR THE PULLEYS/ THE WATERPUMP/ THE ALTERNATOR. TO INSURE IT'S NOT A DEFECTIVE "MEDIC-SCOPE". LISTEN TO YOUR PALS HEARTBEAT!

JUST KEEP IT BACK FROM THE MOVING STUFF A LITTLE----SHOULD YOUR PHONE MAKE A RACKET, AND YOU GET DISTRACTED----YOU MIGHT NEED SOME MEDICAL ATTENTION. OR WORSE

KEEP ME INFORMED

ROGER, ON THE NEW BELT--SOMETIMES THEY MIGHT BE MANUFACTURED WRONG (LIKE ON A FRIDAY--20 MINUTES BEFORE THE WHISTLE BLOWS!) THE PULLEYS THEMSELVES COULD HAVE MEGA WEAR ON THE BELT SURFACE. THE LARGER ONES, MAY BE MORE PRONE TO THIS

A IDLER OR TENSIONER PULLEY OR OTHER PULLEYS MAY HAVE "WOBBLE" ON IT'S SHAFT----CHECK FOR THIS WITH THE BELT OFFTHE TENSIONER COULD "GROW" OUT OF ALIGNMENT AS IT IS ROTATED TO GAIN TENSION (LIKE AN INTERNAL FAULT AT IT'S PIVOT)

ARE YOU 100% SURE THE BELT IS ROUTED RIGHT. NO MODIFICATIONS HAVE BEEN DONE WHERE THE PULLEYS RUN?

"EYBALLING" THE BELT, SORTA PARALLEL WITH IT---ARE THE PULLEYS "IN LINE" NONE PROTRUDING FORWARD OR REARWARD, MAKING THE BELT TRACK "OUT OF PERFECT LINE"?

No modifications, apart from replacement parts. New tensioner and idler pulleys, new belts, and new alternator. Looks as though the new alternator I put it in is protruding out a little from "the line". This could very well be the cause. I will try to adjust it.

Will return with results.

LAYING A YARDSTICK, ETC ON THE SIDES OF THE LARGER PULLEYS MAY SORTA SHOW HOW FAR OUT OF LINE THE OTHER PULLEYS MAY BE.

LEMME KNOW HOW IT'S GOING

The yardstick showed that the alternator pulley was 1/2" out of line. Took it back and got the one that fits right, installed and done. Thank you for your help
