  Q: How to replace the Timing Cover on Cadillac Catera?

  A:

  First, take out the intake air resonator and intake plenum and lift the vehicle, while holding it in place. Then remove the 4 engine splash shield bolts and the engine splash shield. Counterhold the generator bolt on the back side of the generator then remove the air injection crossover pipe bracket nut off generator bolt and remove air crossover pipe bushing nut per bracket on left side of the engine. Remove the air crossover pipe clamps from the rubber hose and remove the air crossover pipe from the air pipe hoses. Lower the car and disconnect the hose clamp and hose from the check valve, and remove the air crossover pipe . Unfasten the Water Pump Pulley bolts, power steering pump pulley bolts, remove the strap bolt that supports the a/c compressor hose to the air injection crossover bracket, and accessory Drive Belt. Prudently pull forward to take out the wiring harness channel cover and let go of the plastic retaining tabs on the wiring harness channel extension and remember the wiring harness routing before taking out the wiring harness from the channel. Remove the bolts holding the Water Pump Pulley and the Water Pump Pulley, the power steering pump pulley bolts and the power steering pump pulley in turn. Next, take out the accessory Drive Belt tensioner bolts and the tensioner; next, the front timing bolt and the cover bolt and the cover. In case applicable, transfer the wiring harness channel and inspect the sealing strip from the outer edge of the front timing belt cover for any cracks or tears and replace it if necessary. For the installation start with the installation of the front timing belt and its bolts which need to be tightened at the rate of 8 nm (71 inch lbs). The accessory Drive Belt tensioner along with its bolts is checked, tightened to 40 nm (30 ft. Lbs.), and the power steering pump pulley along with its bolts checked, when tightened to 20 nm (15 ft. Lbs.). Mount the Water Pump Pulley and fasten it with bolts to 8 nm (71 inch lbs), and route the harness wire into the channel and the channel cover for the wiring harness and extension. Then slot the accessory Drive Belt in place, then install the a/c compressor hose support strap bolt to the air injection crossover bracket, tightening it to 8 nm (71 inch lbs.). Install installing the air crossover pipe and the air check valve at the end of the air hose followed by the air check valve hose clamp. Lift up the vehicle once more this time to fit the air crossover pipe to the air pipe hoses and the air crossover pipe clamps. Assemble the air crossover pipe bushing nut and tighten the same to 12 nm (108 inch lbs.) followed by counterholding the generator bolt in order to install the air injection crossover pipe support bracket nut and tighten in the generator bolt to 40 nm ( 30 ft. Lbs.) finally, install the engine splash shield and its 4 bolts, torque down to 10 nm (89 inch lbs), lower the vehicle, and replace the intake plenum and intake air resonator.

  Q: How to service and repair the timing cover on Cadillac Catera?

  A:

  The service and repair process of the Timing Cover begins by removing the intake air resonator and the intake plenum followed by lifting and supporting the vehicle. Detach the splash shield by removing its 4 mounting bolts. Then extract the splash shield from its position. Start by counterholding the generator bolt on the generator's rear side to detach the air injection crossover pipe bracket nut from the generator bolt and then separate the air injection crossover pipe bushing nut from the engine bracket on its left side. Move on to the next step by unclamping the hydrogen injection crossover pipe from its connections with rubber hoses before removing the crossover tube altogether. Bottom the car then release the hose clamp on the check valve before disconnecting hose connection and removing the air injection crossover pipe. Preserve the accessory Drive Belt tension to create necessary resistance because the Water Pump Pulley bolts and Power Steering Pump bolts should remain in place. Start by unscrewing Water Pump Pulley bolts before moving on to Power Steering Pump pulley bolts. Work on the following sequence to remove the belt: start by taking off the bolt which supports the a/c compressor hose from the air injection crossover bracket. Then remove the accessory Drive Belt. Pull the harness channel forward to expose the cover while releasing the retaining tabs from the extension and remember the harness path before extracting it from its channel. Remove first the Water Pump Pulley bolts accompanied by the Water Pump Pulley then proceed with the Power Steering Pump pulley bolts followed by the Power Steering Pump pulley. Start by uninstalling the accessory Drive Belt tensioner bolts and the tensioner along with the front timing belt cover bolts and cover. The front timing belt cover has a sealing strip at the outer edge which needs to be checked for damage before replacement. Secure the front timing belt cover through bolting and ensure proper torque reaches 8 nm (71 inch lbs.). Mount the accessory Drive Belt tensioner together with its tightening bolts at 40 nm (30 ft. Lbs.). Begin by installing the Power Steering Pump pulley with its bolts set to a medium consistency but final tightening will occur during the accessory Drive Belt installation. After Water Pump Pulley installation place its bolts loosely secured for subsequent tightening. Guide the wiring harness through the channel while installing both the wiring harness channel cover and its extension. When replacing the accessory Drive Belt, users should also put back the a/c compressor hose support strap bolt. Use 8 nm torque (71 inch lbs.) to secure it. Tighten the Water Pump Pulley bolts to 8 nm (71 inch lbs.) tighten the Power Steering Pump pulley bolts to 20 nm (15 ft. Lbs.). Reinstall the air injection crossover pipe and connect the air injection check valve hose using clamps. Lifting the vehicle allows you to connect the air injection crossover pipe to its rubber hose connections. Install the air injection crossover pipe bushing nut and tighten it at 12 nm (108 inch lbs.). Secure the air injection crossover pipe clamps while counterholding the generator bolt to install the air injection crossover pipe support bracket nut , tighten the generator bolt to 40 nm (30 ft. Lbs.). To complete the installation insert the air injection crossover pipe bracket nut, attach the splash shield and install its 4 bolts while ensuring all components are fully engaged without any damage to the parts. Place the vehicle back to its original position before reinstalling the intake plenum and intake air resonator.
