2004 Chevrolet Silverado 3500 Parts Questions & Experts Answers

• Q: How to replace the valve rocker arm and push rods on 2004 Chevrolet Silverado 3500?

  A: You should start by removing the valve Rocker Arm cover and placing all components including pushrods and valve rocker arms and pivot support support into a rack before each step for proper positioning. As the next step remove all valve Rocker Arm bolts and the rocker arms together with pivot support and pushrods. Perform a cleansing operation followed by inspection of valve rocker arms together with pushrods. The process of installation requires clean engine oil for coating valve rocker arms and pushrods plus flange oil application on valve Rocker Arm bolt surfaces. The valve lifter sockets should have pushrods properly seated before you replace the pushrods through the pivot support. Install the pushrods such that they establish proper seating at Rocker Arm ends yet keep the bolts for Rocker Arm installation loose. Turn the Crankshaft to bring the number one Piston to the top dead center compression stroke so the Crankshaft sprocket key reaches the 1:30 slot. Roll the Crankshaft until top dead center compression stroke of the number one Piston occurs while aligning it to the 1.30 position. Subsequently, torque the exhaust valves of cylinders 1, 2, 7, 8 to 30 nm (22 ft. Lbs.) and tighten intake valves of cylinders 1, 3, 4, 5 to 30 nm (22 ft. Lbs.). Proceed by rotating the Crankshaft by 360 degrees before applying torque of 30 nm (22 ft. Lbs.) to the valve Rocker Arm bolts for cylinders 3 through 6 exhaust along with cylinders 2 through 8 intake. The final step is to install the valve Rocker Arm cover.
