Question about 1994 Chevrolet Astro
When my van turns on it sometimes start quiet or it can start with a high pitched noise. the noise will quiet it down as long as i have my foot on the gas pedal, but if i need to make a stop it becomes loud again
YOU CAN REMOVE THE SERPENTINE BELT AND START THE ENGINE BRIEFLY TO SEE IF NOISE IS STILL THERE. IF NOISE IS NOT PRESENT CHECK ALL BELT DRIVEN COMPONENTS FOR LOOSE BEARINGS OR EXCESSIVE MOVEMENT. IF NOISE IS STILL THERE THEN PULL DUST SHIELD UNDER VEHICLE AT FRONT OF TRANSMISSION. THIS WILL ALLOW YOU VISIBLE ACCESS TO THE STARTER DRIVE(THE PART THAT MOVES OUT TO ENGAGE THE FLYWHEEL ON BACK OF ENGINE)WITH AN ASSISTANTS HELP START THE VEHICLE(WEAR SAFETY GLASSES)AND WATCH AND LISTEN. IF THE NOISE IS IN AREA OF FLYWHEEL YOU WILL SEE THE STARTER DRIVE(IT HAS TEETH ON IT)STAYING ENGAGED TO THE FLYWHEEL, IF THIS HAPPENS YOU CAN TRY SHIMMING THE STARTER BUT MOST LIKELY THE STARTER WILL NEED TO BE REPLACED DUE TO A BAD STARTER DRIVE(OR BENDIX) RETURN SPRING. HOPE THIS INFORMATION HELPS!!
