2003 Cadillac Escalade Parts Questions & Experts Answers

• Q: How to replace the pushrod and valve rocker arm on 2003 Cadillac Escalade?

  A: Start the valve Rocker Arm and push rod replacement by taking out the Rocker Arm cover while setting the rocker arms along with pushrods and pivot support in a rack to maintain their positioning. First remove the Rocker Arm bolts from their positions and subsequently remove the rocker arms together with the Rocker Arm pivot support before dealing with the pushrods. The cleaning and inspection process must be performed on the rocker arms and pushrods when needed for replacement. Engine oil should be used to lubricate both rocker arms and pushrods and the bolt flange of Rocker Arm bolts needs lubrication prior to installation. The Rocker Arm pivot support installation needs to be done after the pushrods arrest correctly in the valve lifter sockets followed by Pushrod installation to achieve proper Rocker Arm seat positioning but avoid bolt tightening at this time. To continue with the installation, set the Crankshaft at top dead center (TDC) compression position during which the number one rocker arms align off the lift curve and the Crankshaft key points to the 1:30 position. While engine position is at number one firing mode, you must tighten Exhaust Valve Rocker Arm bolts on cylinders 1, 2, 7, and 8 to 30 nm (22 ft. Lbs.) followed by Intake Valve bolts for cylinders 1, 3, 4, and 5 to 30 nm (22 ft. Lbs.). The torque specification requires 30 nm (22 ft. Lbs.) for all the exhaust Rocker Arm bolts of cylinders 3, 4, 5, and 6 and for all the intake bolts of cylinders 2, 6, 7, and 8. Screw in the Rocker Arm cover as the last step of installation.
