Exhaust Manifold Replacing for Ford and Mercury?

The details are for Ford Taurus and Mercury Sable car model.

The procedure is Exactly the same for both car models.


Exhaust Manifold
REMOVAL & INSTALLATION  details are as follows :----


NOTE
Spray the exhaust system fasteners with penetrating lubricant before removing them to help prevent broken studs and bolts. The use of a 6-point socket is highly recommended when removing exhaust system fasteners.


CAUTION
To prevent serious burns, allow the exhaust manifold to cool down before attempting to remove it.

Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
  1. Remove the LH catalytic converter. Refer to Catalytic Converter.
  2. Remove the LH Heated Oxygen Sensor (HO2S).
  3. Remove the 3 bolts and the LH exhaust manifold heat shield.
  4. Remove the 6 nuts and the LH exhaust manifold. Discard the nuts and gasket.
  5. Clean and inspect the LH exhaust manifold.
  6. Remove and discard the 6 LH exhaust manifold studs.
    NOTE
    Do not use metal scrapers, wire brushes, power abrasive discs or other abrasive means to clean the sealing surfaces. These may cause scratches and gouges resulting in leak paths. Use a plastic scraper to clean the sealing surfaces.
  7. Clean the exhaust manifold mating surface of the cylinder head with metal surface prep. Follow the directions on the packaging.
To install:
  1. Install 6 new LH exhaust manifold studs. Tighten to 106 inch lbs. (12 Nm).
    NOTE
    Failure to tighten the exhaust manifold nuts to specification a second time will cause the exhaust manifold to develop an exhaust leak.
  2. Using a new gasket, install the LH exhaust manifold and 6 new nuts. Tighten in 2 stages in the sequence shown:
    1. Stage 1: Tighten to 15 ft. lbs. (20 Nm).
    2. Stage 2: Tighten to 15 ft. lbs. (20 Nm).

  3. Install the LH exhaust manifold heat shield and the 3 bolts. Tighten to 89 inch lbs. (10 Nm).
  4. Install the LH HO2S .
  5. Install the LH catalytic converter. Refer to Catalytic Converter.
  6. Start the engine and check for exhaust leaks.

  1. Remove the RH catalytic converter. Refer to Catalytic Converter.
  2. Remove the RH Heated Oxygen Sensor (HO2S).
  3. Remove the 3 bolts and the RH exhaust manifold heat shield.
  4. Remove the 6 nuts and the RH exhaust manifold. Discard the nuts and gasket.
  5. Clean and inspect the RH exhaust manifold.

  3. Install the RH exhaust manifold heat shield and the 3 bolts. Tighten to 10 ft. lbs. (14 Nm).
  4. Install the RH HO2S.
  5. Install the RH catalytic converter. Refer to Catalytic Converter.
  6. Start the engine and check for exhaust leaks.

This details will help.
Thanks.
