  Q: How to replace the timing belt without variable camshaft phasing on Chevrolet Aveo?

  A:

  You may replace a Timing Belt by starting with disconnecting the negative Battery Cable and the intake air temperature sensor connector followed by removing the Throttle Body tubing for the air intake system and the valve cover tube for the breather system. Start the procedure by eliminating the air filter housing bolts and then taking out the air filter housing and moving on to the right front wheel and splash shield. First remove the accessory Drive Belt along with the Crankshaft Pulley bolt and then detach the Crankshaft Pulley. You should remove first the upper and lower front Timing Belt covers then proceed to uninstall the power steering pump mounting bolts when they exist. Attach the Crankshaft Pulley bolt to its position while turning the crankshaft clockwise until you see the timing mark on the Crankshaft Gear at the bottom of the rear Timing Belt cover. A light adjustment of coolant pump retaining bolts permits the j 42492-a (KM-421-A) Timing Belt adjuster tool to remove the Timing Belt. The installation process first requires positioning the Crankshaft Gear timing mark with the rear Timing Belt cover mark while keeping the exhaust camshaft gear dowel pin at the 11 o'clock position and then achieving correct camshaft gear alignment before fitting the new Timing Belt. Using the j 42492-a (KM-421-A) adjuster turn the coolant pump clockwise until the adjust arm pointer of the Timing Belt automatic tensioner points at the notch in the bracket. Follow the steps to first tighten the coolant pump retaining bolts to 10 nm (89 lb in) before rotating the crankshaft clockwise two full revolutions. Then, loosen the coolant pump retaining bolts. Set the coolant pump using the j 42492-a (KM-421-A) adjuster until the adjust arm pointer matches the bracket pointer on the Timing Belt automatic tensioner. Then tighten the bolts to 10 nm (89 lb in). First remove the Crankshaft Pulley bolt then replace it with the upper and lower front Timing Belt covers and secure their bolts at 10 nm (89 lb in). The Crankshaft Pulley and bolt need to be tightened to 95 nm (70 lb.ft) with a torque wrench before a j 45059 angle meter or km-470-b angular torque gage is used to provide an additional 30 degrees with 15 degrees torque to the Crankshaft Pulley bolt. The sequence of replacement includes the accessory Drive Belt if present and the right front splash shield and right front wheel and air filter housing which needs bolts tightened to 8 nm (71 lb in). Following the connection of the Throttle Body to air intake tube and breather tube comes the restoration of the iat sensor connector and the negative Battery Cable reinstallation.
