Q: How to replace the pushrods and valve rocker arm on Chevrolet Equinox?
A: The valve Rocker Arm replacement procedure begins by eliminating the valve Rocker Arm cover(s) and Rocker Arm bolt(s). The valve Rocker Arm(s) and Pushrod(s) should then be removed before the process continues. The push rods need to have their ends coated with prelube gm p/n 1052367 (Canadian P/N 992869) or an equivalent which should be used to install the 146.0 mm (5.75 inch) intake valve push rods and the 152.5 mm (6.0 inch) exhaust valve push rods back to their original positions. Apply the prelube material to the surfaces that require friction between each Rocker Arm. Shim installation under valve Rocker Arm pedestals becomes necessary when Cylinder Head reconditioning has been performed or its components have undergone any work. The valve rocker arms should receive their original positioning while valve Rocker Arm bolts need installation and torquing to 42 nm (31 ft. Lbs.). Reinstall all valve Rocker Arm covers as the final step of the process.
Q: How to replace the pushrod and valve rocker arm on Chevrolet Impala?
A: The rack should hold valve train components in their correct sequence before replacing valve rocker arms and push rods. Start the procedure by taking off valve Rocker Arm covers and then easing valve Rocker Arm bolts before pulling out rocker arms and pushrods. The intake push rods amount to 147.51 mm (5.81 in) yet exhaust push rods span to 154.87 mm (6.1 in). Another essential step involves applying prelube to pushrods before their installation where blue-stripped exhaust pushrods should reside in the lifter bore and yellow-stripped intake pushrods must occupy the correct position. Distribute prelube material over the surfaces that will experience friction between rocker arms. The procedure of reconditioning a Cylinder Head or its components requires the use of shims (88894006) under the valve Rocker Arm pedestals. First install the rocker arms before tightening the bolts to 34 n.m (25 lb ft). Then move on to install the valve Rocker Arm cover(s).
Q: How to replace the pushrods and valve rocker arm on Chevrolet Malibu?
A: Beginning a valve Rocker Arm and push rod replacement starts with removing the valve Rocker Arm covers then separating the components for correct reinstallation. First extract the Rocker Arm bolts and after that remove the rocker arms from the components yet maintain the original positions for the pushrods. After that, remove the pushrods. Before assembly you should treat the ends of pushrods with gm p/n 1052356 chemical or equivalent materials. The two types of pushrods feature yellow stripes for intake pushrods measuring 5 3/4 inches and green stripes for exhaust pushrods at 6 inches in length; check that both types seat correctly inside the lifter. Add pushrods back into their previous positions which should be followed by installing the rocker arms. The installation process requires fitting the Rocker Arm bolts which need 14 nm (124 inch lbs.) torque and additional 30 degrees tightening through the j 36660-a torque angle meter. You should install the valve rocker covers in the final stage.
