  Q: How to Service and Repair the Right Exhaust Manifold on Chrysler LHS?

  A:

  Disconnecting the negative cable from the jumper terminal and putting the car on a hoist are first steps to replace the exhaust manifold. Take off the exhaust, next loosen the bolt attaching the converter pipe to the transaxle mount and then loosen the A/C serpentine belt before letting the car fall away from the truck. After that, take off the air cleaner housing and the air inlet tube and remove the V-Band clamp from the exhaust manifold connector, without using it again. Loosen the compressor bolts and lay the unit aside and then detach the engine oil dipstick tube and the A/C compressor bracket. Release the Oxygen Sensor electrical connector, remove the sensor and remove the heat shields after taking out their attaching bolts. Take out the connecting bolts from the exhaust manifold and then remove the exhaust manifold and replace it with a new gasket. Look for harm or splits on the exhaust manifolds, examine the gasket for alterations and check the surface beneath the cylinder head for any misalignment. After installing the exhaust manifold and gasket, first tighten the bolts from the center outward, to about 23 Nm (200 inch lbs.). After fitting the heat shields, bolt each in place to 105 inch lbs (12 Nm) and install and connect the oxygen sensor to the manifold's electrical connector. Connect the mounting bracket for the A/C compressor, the engine oil dipstick tube and the A/C compressor and then add the Drive Belt. Replace the clamp at the V-Band junction, set the tightness to 11 Nm (100 inch lbs.) and lift the vehicle on the hoist to put in the exhaust system. Secure the nut holding together the converter pipe support and transaxle mount to 47 Nm (35 ft. lbs.), set the car back on its wheels and then add the air cleaner housing and air inlet tube prior to connecting the negative battery cable.

  Q: How to Maintain Your Exhaust Manifold Effectively on Chrysler LHS?

  A:

  The first step toward servicing the exhaust manifold is to remove the negative cable from the remote jumper terminal and then raise the vehicle with a hoist. Taking out the exhaust, unscrew the bolt that holds the converter pipe support to the transaxle mount, remove the A/C belt and bring the vehicle partially down. Take out the air cleaner housing and air inlet tube, then loosen and take out the clamp from the exhaust manifold connector, avoiding reusing it. Then, loosen and remove the bolts that hold the air conditioning compressor to the engine, put the compressor aside and take out the engine oil dipstick tube and the air conditioning compressor bracket. Take out the electrical connector for your Oxygen Sensor, then remove the sensor. After that, unsure and take the heat shield out by undoing the bolts connecting it to the exhaust manifold. Once the rest of the exhaust assembly is detached, take off the exhaust manifold attaching bolts and the manifold. When mounted, place the exhaust manifold and tighten the center bolts to 23 Nm (200 inch lbs.) and mount the heat shields securing them with bolts tightened to 12 Nm (106 inch lbs.). Place the oxygen sensor onto the manifold, attach its electrical connector, put on the air conditioning compressor bracket and lastly attach the oil dipstick tube to the engine. Put back the air conditioning compressor, Drive Belt and a new V-Band clamp, securing the clamp to 11 Nm (100 inch lbs.) Lift the vehicle on the hoist, set in place the exhaust system and screw the nut attaching the converter pipe support to the transaxle output mount to 47 Nm (35 ft. lbs.). Set the suspension to a low position, replace the air cleaner housing and air inlet tube and attach the negative cable once more. The procedure for the left exhaust manifold is like that of the right: remove the negative cable, raise the car with a hoist, remove the exhaust and detach the strap holding the converter pipe bolt at the transaxle. Take off the V-Band clamp at the exhaust manifold connector, but don't reuse it, then remove the bracket for the connector harness and disconnect the oxygen sensor connector to take out the sensor from the manifold. Lift out the heat shield, then unscrew the bolts holding it in place. Repeat this with the manifold and its attaching bolts. First, put the exhaust manifold in place and tighten the bolts in the middle going outward to 23 Nm (200 inch lbs.) and then set the heat shields and tighten their bolts to 12 Nm (105 inch lbs.). Install the sensor in the manifold, attach the electrical connector, attach the connector bracket to the brace and secure a new V-Band clamp (torque it to 11 Nm / 100 inch lbs.). After raising the vehicle, attach the nut securing the converter pipe support to the mount on the transaxle; tighten it to 47 Nm (35 ft. lbs.), install the exhaust system, lower the vehicle and attach the negative cable again.
