  Q: How to Service and Repair the Intake Manifold on a Chevrolet Lumina?

  A: You must start by disconnecting the battery ground cable to replace a lower Intake Manifold. Start by removing the upper Intake Manifold before disconnecting the radiator inlet hose along with the Thermostat bypass hose and completing the removal of the Thermostat bypass pipe. The work sequence requires removal of three parts: the left valve Rocker Arm cover and generator and the right valve Rocker Arm cover. Begin by disconnecting the engine coolant temperature (ECT) wiring harness and removing the Fuel Injector and manifold air pressure (MAP) wiring harness. Next detach the fuel pipe clip bolt and its retaining clip. Begin by removing the fuel feed and return pipes that attach to the Fuel Injector rail before taking the Fuel Injector rail off. Move the Power Steering Pump to a suitable location before disconnecting the heater inlet pipe connected to the lower Intake Manifold through a heater hose. The procedure requires removal of the lower Intake Manifold bolts followed by the lower Intake Manifold and valve rocker arms and push rods. The technician cleans all seal and gasket areas on both the engine block and cylinder heads before removing residual rtv sealer. When installing a new lower Intake Manifold begin by taking off the ect sensor and water outlet bolts before removing the water outlet. The water outlet must be bolted down with 25 nm (18 ft. Lbs.) torque during installation if you take off the Thermostat or water outlet. Reinstall the ect sensor when it has been removed. Place an 8-12 mm bead of rtv sealer (GM P/N 12345739 or equivalent) on the lower Intake Manifold contact ridges between the engine block then install lower Intake Manifold gaskets followed by push rods and valve rocker arms. Apply gm p/n 12345382 sealant to all lower Intake Manifold bolt threads and tighten the vertical and diagonal bolts to 13 nm (115 inch lbs.) apply a torque of 13 nm (115 inch lbs.) when tightening the diagonal bolts. Hand tighten the vertical and diagonal lower Intake Manifold bolts, then tighten the vertical bolts to 13 nm (115 inch lbs.) and the diagonal bolts to 13 nm (115 inch lbs.). First install both the Power Steering Pump and the heater inlet pipe with its attached heater hose before reattaching the Fuel Injector rail. Position the fuel return and feed pipes onto the Fuel Injector rail while securing the fuel pipe clip with a torque of 8 nm (71 inch lbs.). Begin by connecting the Thermostat bypass hose and radiator inlet hose followed by installing the Fuel Injector and map wiring harness and the ect wiring harness. As a conclusion reinstall the right and left valve Rocker Arm covers with the generator and upper Intake Manifold followed by reconnecting the battery ground cable.

  Q: How to replace the rear side outer door handle on Chevrolet Lumina?

  A: Start the rear side door outside handle replacement by removing both trim panel and water deflector. Use side cutters to sever the outside handle rod-to-lock clip from the lock before you unscrew the remaining part of the clip from the rod and dispose of it. Remove the two rivets securing the outside door handle by drilling and take out the parts from the rod and door. Once installed you should first attach the outside door handle rod to the door handle followed by installing the handle together with the rod to the door. Take rivets to secure the handle then add a new outside handle rod-to-lock clip onto the door lock lever and position the rod inside the clip to prevent free movement. The installation ends with placement of the water deflector along with the trim panel while the threaded outside door handle rod passes beneath the clip cover.

  Q: How to Service and Repair an Alternator for Rear on Chevrolet Lumina?

  A: Start by removing the generator rear brace stud from the generator then remove the generator rear brace nut from the engine stud on the engine Intake Manifold and finally detach the generator rear brace. First secure the generator rear brace to both generator and engine Intake Manifold engine stud before loosely attaching the generator rear brace stud to the generator body. Install the generator rear brace nut onto the engine stud on the Intake Manifold with a torque action of 25 n.m (18 lb ft) followed by generator rear brace study torque at 25 n.m (18 lb ft).

  Q: How to replace the left front wheel drive shaft wheel seal on Chevrolet Lumina?

  A: Start the procedure for left front wheel drive shaft oil seal replacement by adequately supporting the vehicle through proper vehicle lifting. Start replacement by removing both the left front tire and wheel and then the left engine splash shield. Detach the stabilizer shaft brackets from the left lower Control Arm before you remove both Tie Rod End from the left Steering Knuckle and the left lower Ball Joint from the left lower Control Arm. The left drive axle requires disconnection from the transaxle before securing it to the left Steering Knuckle and strut. A suitable tool such as a screwdriver should be used to remove seal (409) from its bore while protecting the bore's surface. Apply transaxle fluid on the seal lip before inserting a new seal (409) using the left side axle seal installer (J34115) along with the axle seal protector (J37292-B) inside it. While inserting the Axle Shaft ensure it passes by the lip seal without the splines touching the lip surface to avoid seal damage. After reattaching the drive axle connect to the transaxle operator should remove the axle seal protector (J37292-B) to start left lower Ball Joint installation onto the left Control Arm and then left Tie Rod End installation onto the left wheel knuckle followed by the left stabilizer shaft bracket installation onto the left Control Arm. Put back the left engine splash shield followed by installing the left front tire and wheel. Then lower the vehicle. Another requirement entails checking the fluid level to the specified amount while inspecting that the repair work was correctly finalized without leaks.
