TENSIONER PART NUMBER: 305
Installation Instruction:
Remove the serpentine belt by using a breakover bar, ratchet, or serpentine belt installation tool
with the correct size socket for the pulley mounting bolt. Rotate the tensioner arm to release
tension. Remove the belt. Using the proper size socket, remove the tensioner mounting bolt, and
remove the tensioner.
Before installing the new tensioner, make sure the mounting surface for the tensioner is clean and
free from rust or other obstructions. Find the locator pin holes, and rotate the replacement
tensioner until the locator pins and the holes line up, and insert the pins into the holes. Reinstall
the mounting bolt, and torque down to a tight fit.
Using the proper size socket again, rotate the tensioner arm to install the serpentine belt. Making
sure the belt is correctly fitted to all the pulleys in the drive system, start the engine to check for
any problems. Extreme care should be taken when reinstalling the serpentine belt because some
of the pulleys are located in remote positions and it is very hard to see that the belt is seated
properly in all of the grooves. If the belt isn't seated properly, the belt can "ride out" of the
grooves and the belt can be damaged.
