How to Replace the Timing Belt on a Chevy Aveoby Carl Pruit
According to the website listed below in the Resources section, it is recommended that you inspect and change your timing belt on the Chevy Aveo every 60,000 miles to maintain proper performance of your engine. This recommendation applies to all engine sizes and models of the Chevy Aveo, and you can change the timing belt yourself in about four to six hours, saving yourself a lot of time and expense in the process.
Detach the negative battery cable from the battery of your Chevy Aveo with an open-end wrench and move the cable out of the way, so that it does not touch any other metal parts.
Raise the vehicle up with a floor jack on the right front side, so that you can slide a jack stand under the front axle under the passenger side, and then lower the vehicle down until the axle is sitting on the jack stand.
Unfasten the air mass plug from the air cleaner by pulling it straight out, and then remove the air cleaner from the engine by undoing the wing nut on the top of the cleaner.
Detach the upper timing belt cover by using a socket wrench to remove the bolts, then pull the cover away from the engine.
Remove the right front passenger tire by using a lug wrench and undoing the lug nuts, then lay the tire and lug nuts aside.
Detach the plastic wheel well cover by pulling it back and unfastening the clips holding it to the vehicle.
Remove the lower timing belt cover by unfastening the bolts with a socket wrench and pulling the cover away from the engine.
Use the belt removal tool on one of the camshaft sprockets and turn it clockwise to loosen the timing belt, then slide it off the sprocket.
Detach the vibration/damper pulley located between the camshafts and crankshaft with a socket wrench, and then set it aside.
Turn the crankshaft with a socket wrench by turning the bolt in the center of the sprocket clockwise until the marks on the sprocket are pointed vertically downward and the marks on the camshaft sprockets are pointed horizontally toward each other.
Lock the camshafts into place by positioning the locking tool between the two camshafts, then loosen the tensioner pulley with the socket wrench and remove the timing belt.
Position the new timing belt over the crankshaft and attach a new tensioner pulley to the engine block with a socket wrench; adjust the tension using the Torx bolt provided with the pulley.
Remove the fastening bolt on the new tensioner pulley and tighten the tension to 20 to 22 foot pounds with a torque wrench.
Loop the timing belt over the two camshafts and reattach the vibration dampener pulley; use a torque wrench to tighten the pulley to 20 foot pounds.
Reattach the lower timing cover over the timing belt case with bolts and then slide the top cover over the timing belt and secure it with bolts.
Fasten the air cleaner back over the Chevy Aveo engine and then attach the air mass plug to the side of the air cleaner.
Reattach the plastic wheel well cover under the right front tire area by snapping the pins into place.
Put the right front tire back on the car and attach the lug nuts with the lug wrench, then reattach the negative battery cable.
Start the engine and verify that the timing belt is operating correctly, then shut the engine off.
- Before removing the timing belt, sketch out the position of the belt and how it winds around the parts so that you can replace it in the right position.
