2006 Mercury Grand Marquis Exhaust Manifold Parts Questions & Experts Answers

• Q: How to service the right-hand exhaust manifold on 2006 Mercury Grand Marquis?

  A: Persons servicing the right-hand exhaust manifold must first disconnect the fire suppression system when available since the procedure demands safety precautions. First secure the vehicle on a hoist when it is in neutral with a disconnected negative battery cable. Follow this step by winding the drive belt tensioner in a clockwise direction to remove the belt. From there you can disconnect the vehicles crankshaft position sensor connection and the A/C compressor electrical wires. First uninstall the bolt from the transmission cooler tube bracket and afterward remove the nut to set the transmission cooler tube assembly aside. Proceed by removing three bolts to position aside the A/C compressor before working on the three catalytic converter-to-exhaust manifold nuts which remove the catalytic converter flange. You should first discard the old gasket while removing both the exhaust manifold and eight nuts together. Start by applying the new exhaust manifold gasket onto the manifold part before tightening all eight nuts in order to 25 Nm (18 ft. lbs.). After attaching the catalytic converter flange reinstall its nuts by tightening them to 34 Nm (25 ft. lbs.). Secure the A/C compressor through three bolts by tightening them to 25 Nm (18 ft. lbs.). Install the transmission cooler tube assembly by tightening the nut to 9 Nm (80 inch lbs.) and bolt connecting the transmission cooler tube bracket with 15 Nm (11 ft. lbs.). The procedure demands returning the CKP sensor electrical connector and A/C compressor electrical connector after rotating the drive belt tensioner clockwise to reinstall the drive belt and reattaching the negative battery cable. A repowered installation of the fire suppression system should be performed.
