  1. 1

    Purchase a new timing belt at an auto parts store. You need to inspect the belt before you install it.

  2. 2

    Check the teeth of the new belt, look for timing marks that you will match up to the cam and the crank and make sure that the belt is stiff with no thin spots.

  3. 3

    Take the old belt off-loosen the bolts that keep the sprockets tight and slip the old timing belt off.

  4. 4

    Slide the new timing belt on to the sprockets. You will need to loosen the bolts up even more to install the new belt. As you loosen the bolts, the belt will connect to the sprocket naturally.

  5. 5

    Adjust the tension of the belt to 1,3,4,2.

  6. 6

    Turn the motor over manually so the belt will connect to the sprocket-the teeth of the belt and the sprocket need to line up.

  7. 7

    Count the timing marks on the cam and the crank and match with the timing marks on the new belt. Refasten the timing covers and reattach the battery cables. Start the car.

Tips and warnings

  • Do not rotate the crankshaft or camshaft after removing the timing belt--this could cause engine damage.
