2010 Chevrolet Cobalt Parts Questions & Experts Answers

• Q: How to replace the exhaust camshaft and lash adjuster on 2010 Chevrolet Cobalt?

  A: The first step when replacing exhaust camshaft and valve lifters involves uninstalling the camshaft position exhaust actuator. Make a mark on the camshaft bearing caps before removing the bolts on each cap in small increments until you eliminate the spring tension from the camshaft. Begin by untightening rectangles at camshaft bearing caps and then removing the cap alongside the exhaust camshaft. Keep the rocker arms and hydraulic valve lash adjusters readily available for future reinstallation. Next follow steps to take out both valve rocker arms and hydraulic valve lash adjusters. When installing hydraulic valve lash adjusters place them in their bores before lubricating both these components and valve tips together with rocker arms. The original positioning of used rocker arms on the camshaft must be maintained while any replacement of the camshaft requires new rocker arms. After setting the valve rocker arms on their respective locations and valve lash adjuster positions properly lubricate them before installing the exhaust camshaft while making sure it receives lubrication. The bearing caps must be installed according to their indicated sequence on the caps before applying hand torque to the bearing cap bolts. Users should proceed with extra care when they are tightening fasteners. Tighten the bearing cap bolts in three-turn increments while installing them to obtain a final torque of 10 nm or 89 lb in. You need to install the camshaft position exhaust actuator as the last step.
