  Q: How to Service and Replace the Pushrod on a Cadillac Escalade?

  A: Before proceeding with valve Rocker Arm and push rod replacement you must remove the Rocker Arm cover. The correct engine firing pattern starts with numbers 1 and 8 then progress to 7 and 2 subsequently followed by 6 and 5 and 4 and 3 ending with numbers 1 and 3. The left-bank consists of cylinders 1, 3, 5, and 7. Start by removing the number one cylinder Spark Plug then arrange all rocker arms with pushrods and pivot support on a rack for their subsequent original installation. Begin the process by taking off each Rocker Arm bolt and continuing with the rocker arms behind it and finally the Rocker Arm pivot support and pushrods. The rocker arms alongside pushrods require cleaning and inspection according to need. The reinstallation process requires passengers to apply clean engine oil to both rocker arms and pushrods as well as to lubricate the flange portion of the Rocker Arm bolts. Install the Rocker Arm pivot support by verifying valve lifter sockets receive the pushrods correctly before fitting pushrods into the Rocker Arm ends without bolt torque yet. Follow engine firing sequence when installing the rocker arms and bolts. After turning the Crankshaft to place the number one Piston at tdc compression, verify that all number one cylinder rocker arms are in a lobe lift position. The appropriate torque for the exhaust valve bolts of cylinders 1, 2, 7, and 8 should be set to 30 n.m (22 lb ft) while the intake valve bolts of cylinders 1, 3, 4, and 5 require 30 n.m (22 lb ft). The Rocker Arm bolts guiding exhaust valves for cylinders 3, 4, 5, 6 as well as those leading intake valves for cylinders 2, 6 7, 8 require 30 n.m (22 lb ft) of torque while the Crankshaft rotates 360 degrees. Finish the installation by placing back the number one cylinder Spark Plug together with the Rocker Arm cover.
