  Q: How to replace the camshaft with variable camshaft phasing on Chevrolet Aveo?

  A:

  To change the Camshaft to variable Camshaft phasing, start by removing Camshaft intake and exhaust sprockets, timing belt tensioner and timing belt rear cover. Then, pull off the Camshaft position solenoid valve housing, then remove caps and bolts from the Camshaft caps in the sequence (1, 4, 2, 3). Carefully lift out and take out the intake and exhaust camshafts and seal rings without any scratches or damage to the camshafts and caps bearing surfaces. When being installed, coat and lubricate the Camshaft Bearing and cam with clean engine oil, avoiding any application of the sealant outside the areas marked for sealing. Use the camshafts (1, 2) to be fixed on the cylinder head, with the grooves next to the sealing surfaces not to have the sealant. Apply surface sealant loctite 574 on sealing surface of the 1st Camshaft Bearing cap thinly and evenly and install the Camshaft Bearing caps in the order (2, 3, 1, 4). Tighten Camshaft Bearing cap bolts to 8 nm (70.8 lb in) with the Camshaft position solenoid valve housing. Replace the Camshaft oil seal rings using km-422 and reinstall the timing belt rear cover with tightening the bolts for the timing belt rear cover to 6 nm (53.1 lb in). Last, install the Timing Belt Tensioner and Camshaft intake and exhaust sprockets.

  Q: How to service and repair the camshaft on Chevrolet Aveo?

  A:

  Start the Camshaft service and repair by measuring its lift, and change it if the lift is not 46.3 mm (1.8228 in). Next, check the outer diameter of the Camshaft journals at four different points; if it's not between 27.939 and 27.960 mm (1.1000-1.1008 in), replace the Camshaft. Measure the straightness of the Camshaft using a dial gauge; if it goes past 0.04 mm (0.0016 in), change the Camshaft. Measure the Camshaft endplay using a dial gauge, and exchange the Camshaft if the result goes over 0.130-0.215 mm ( Make sure to measure the inner diameter of the Cylinder Head journal at two places, then replace the Cylinder Head if the measurement falls outside 28.000 and 28.021 mm (1.1024-1.1032 in).
