  Q: How to service and repair the LH exhaust manifold on Mercury Villager?

  A:

  Service and repair of the LH exhaust manifold requires beginning with radiator Fan Motor shroud removal followed by disconnecting HO2S electrical connector. Service the exhaust manifold heat shield by extracting its bolts then position the oil level indicator tube to the side. To proceed further detach the A/C compressor Drive Belt by loosening both the tensioner bolt and the belt tension adjuster bolt. You must first separate the A/C compressor while uninstalling four bolts from its base. Follow the series of steps to remove the LH exhaust manifold nuts with a two-step procedure before elevating the vehicle to remove the engine splash shield. First remove the engine splash shield and exhaust heat shield by undoing all bolts connecting them to the exhaust manifold. Next remove the exhaust manifold to outlet pipe nuts by taking out the bolts. You should begin by disassembling the RH exhaust manifold to engine lifting eye hook bracket by removing the bolts before taking out the three nuts that eventually lead to the exhaust manifold removal. Discard the exhaust manifold gasket. Begin by placing the new exhaust manifold gasket before setting up the exhaust manifold in place using three securing nuts. Install the RH exhaust manifold to engine lifting eye hook bracket with the bolts before securing the exhaust heat shield to its proper position using the bolts. After installing the outlet pipe nuts to the exhaust manifold follow the protocol of engine splash shield installation before lowering the vehicle. Begin by installing the specified sequence of LH exhaust manifold nuts then place and bolt down the A/C compressor to the seal location. After repositioning the drive belt of the A/C compressor you should adjust its tension. You must install the exhaust manifold heat shield while correctly positioning the oil level indicator tube and connect the HO2S electrical connector before reinstalling the radiator fan motor and shroud.

  Q: How to service the RH exhaust manifold on Mercury Villager?

  A:

  Service of the RH exhaust manifold begins with disconnecting both the battery ground cable and battery junction box electrical connectors. Start by taking out the air cleaner assembly while positioning the battery junction box away by removing its bolts and unclipping the retainer. You should remove the exhaust heat shield through bolt removal. The removal process starts by unscrewing the bolts which connect RH exhaust manifold to engine lifting eye bracket. Remove the three LH exhaust manifold to RH exhaust manifold nuts. Raising the vehicle enables you to remove the exhaust manifold heat shield through bolt removal from three locations. The two-step method for exhaust manifold nuts removal must be performed in specified sequence before you lower the vehicle to extract the exhaust manifold. When you lift the vehicle for the second time you should get rid of the exhaust manifold gasket. NEW exhaust manifold gaskets should be positioned before lowering the vehicle to fit the exhaust manifold into its location. The technician should install exhaust manifold nuts in their specified sequence before installing the exhaust manifold heat shield by ensuring proper positioning plus bolting it to three points. Return the vehicle to the lower position so you can install three LH exhaust manifold to RH exhaust manifold nuts before placing and installing the RH exhaust manifold to engine lifting eye bracket with its bolts. Position the exhaust heat shield properly then bolt it into place. The battery junction box requires reinstallation by placing it correctly before clipping it into position and securing the bolts. After finishing reinstall the air cleaner assembly proceed to connect the battery junction box electrical connectors along with reconnecting the battery ground cable.
