2007 Buick Terraza Parts Questions & Experts Answers

• Q: How to replace the valve rocker arm and push rods on 2007 Buick Terraza?

  A: You need to arrange valve train components on a rack for keeping the original sequence before starting the replacement process. In order to proceed, first remove the valve Rocker Arm covers before removing the valve Rocker Arm bolts and rocker arms and pushrods while recording that the intake pushrods measure 147.51 mm (5.81 in) and exhaust pushrods measure 154.87 mm (6.1 in). Before installing the pushrods into the lifter bore apply prelube to their ends. Place the intake pushrods with yellow stripes into their proper slots followed by the exhaust pushrods with blue stripes as per their matching bore. The application of prelube to Rocker Arm surfaces should be accompanied by additional shims (88894006) under valve Rocker Arm pedestals when any reconditioning work has been done on the Cylinder Head or its components. Add the rocker arms to the location before screwing in the Rocker Arm bolts which require 34 n.m torque (25 lb ft). After securing the Rocker Arm bolts, place on each valve Rocker Arm cover.
