2006 Chevrolet Avalanche 2500 Parts Questions & Experts Answers

• Q: How to replace the pushrod and valve rocker arm on 2006 Chevrolet Avalanche 2500?

  A: The sequence for installation requires marking and categorizing the parts before reassembly for correct placement. Start by taking off the valve Rocker Arm cover then proceed to unfasten the valve Rocker Arm nuts, balls and arms from the assembly. When replacing the valve pushrods you must use exhaust pushrods which exceed the length of intake pushrods. Move on to separate the valve Rocker Arm studs from Pushrod guides while cleaning and inspecting both valve rocker arms and pushrods. Sealant gm p/n 12346004 (Canadian P/N 10953480) should be used on the valve Rocker Arm stud-to-cylinder head threads before installing Pushrod guides and valve Rocker Arm studs which require 50 nm (37 ft. Lbs.) torque. Install the exhaust valve pushrods because their length exceeds the length of intake valve pushrods during the assembly process. Put lubricant gm p/n 12345501 (Canadian P/N 992704) on valve Rocker Arm and valve Rocker Arm ball bearing parts before installing the valve rocker arms and valve Rocker Arm balls with their companion nuts. Tighten these nuts to 25 nm (18 ft. Lbs.) during the process of guiding the Rocker Arm tips onto the valve tips. Install the valve Rocker Arm cover as the last step.
