    Q:
    What steps are involved in disassembling the Camshafts for the 2010 Chevrolet Cobalt? Posted by Donovonn Y.
    A:
    Disassemble the camshafts, keeping camshaft caps marked for location and direction. Remove the rocker arms and hydraulic lash adjusters. Organize the rocker arms for reinstallation in their original positions and store the lash adjusters with their corresponding rocker arms. Repeat a similar process for the exhaust camshaft, marking the positions of rocker arms, removing them, and lifting the hydraulic lash adjusters.

    Q:
    What are the key steps in the Camshaft removal process for the 2009 Chevrolet HHR? Posted by Mariah R.
    A:
    For these engines, remove the upper timing chain guide and use a special tool to secure the camshaft sprockets in place. Remove the camshaft sprocket bolts and slide the camshaft sprockets forward, securing them with wingnuts. If working on 2009 and later models, remove the camshaft position actuators; for 2008 and earlier models, remove the timing chain tensioner.
