• Q: How to replace the exhaust and Lash Adjuster in an engine on 2004 Chevrolet Malibu?

  A: The replacement of exhaust and lash adjusters begins with removing the Camshaft cover and upper Timing Chain Guide. Use the Camshaft sprocket holding tool (J 43655) to remove the exhaust and intake Camshaft sprocket bolts which you should discard. Use a marker to create reference points on the bearing caps before you advance the Camshaft sprockets. Follow these steps under hp steering wheel lock systems: remove each bolt on each cap one turn at a time while monitoring the Camshaft spring tension and afterward remove the bearing caps, exhaust Camshaft, camshaft roller followers, and hydraulic element lash adjusters in order. Installing begins by lubricating valve tips then installing the hydraulic element lash adjusters before the Camshaft roller followers while keeping alignment notches matched to the Camshaft sprocket. First install the exhaust Camshaft and Camshaft bearing caps followed by torqueing the Camshaft bearing cap bolts in 3-turn increments until they reach their first seating point then finish the torque at 10 nm (89 inch lbs). Place the Camshaft sprockets on the camshafts first and loosely tighten the new Camshaft sprocket bolts. Then remove the Camshaft sprocket holding tool (J 43655) before torquing the Camshaft sprocket bolts to 85 nm (63 ft. Lbs.) while turning them an additional 30 degrees. To complete the installation phase, complete guide installation by securing the upper Timing Chain Guide with a 10 nm (89 inch lbs) torque and then replace the Camshaft cover.
