Has your Corvette Serpentine belt started making noise or fell off?
LETS FIX IT
YOUR BELT IS NOISY AND THAT SO CALLED DRESSING DOES NOTHING FOR IT, WELL IT IS TIME TO CHANGE THE BELT AND TENSIONER.
Be thankful that replacing the belt and tensioner is not a real hard job, you will need a 15mm wrench and a 1/2 breaker bar or belt tensioner bar.
Lets get started.
Get the correct belt and tensioner for you Corvette, suggest a Chevy dealer and get a factory authorized part.
This is for a C4, to access the area, remove the mass air flow sensor and the flexible duct by unclipping the mass air flow sensor from the air inlet duct at the front, then loosening the band clamp that holds the flexible duct onto the throttle body. Remove the flexible duct and position the mass air flow sensor off to the side.
Now disconnect the mass air flow sensor wiring harness and remove the sensor and duct. You now have an open area for access to the belt.
Before removing the belt, make sure,* MAKE SURE* you have a belt routing diagram or decal, usually located on the top of the radiator shroud. If not, diagram in the owner's manual. If you do not have either of these, draw a diagram or take a picture, without it, routing the new belt will be a nightmare.
To remove the belt, place the end of the breaker bar or tensioner bar into the square hole on the belt tensioner. Press the tensioner down to relieve the tension on the Serpentine belt, so it can easily be removed. Carefully remove the belt from each of the pulleys.
Compare the new belt to the old one to make sure you have the right and correct one. Place both belts on each thumb, and spread your arms apart. The new belt should be slightly shorter, because the old belt has stretched with use. If the belt tensioner is loose, weak or broken, you will have to replace it. Use a 15MM wrench to remove the tensioner retaining bolt, now slide the tensioner out.
Installing the tensioner, align the tab on the tensioner with the alignment slot in the bracket. Install the retaining bolt and torque to 60 ft. lbs.
Route the new serpentine belt onto the pulleys, as indicated by the routing diagram. Make sure the belt is aligned properly with each pulley and the grooves in the belt align with the grooves in the corresponding pulley.
Place the end of the breaker bar or tensioner tool into the belt tensioner slot, then push the tensioner down and install the new belt over the tensioner pulley.
