2000 Mercury Cougar Exhaust Manifold Parts Questions & Experts Answers

• Q: How to service and repair the exhaust manifold on 2000 Mercury Cougar?

  A: The procedure to work on the exhaust manifold begins with removing its heat shield. The service and repair of the exhaust manifold begins with removing upper bolts and coolant hose bracket and engine lifting eye and engine oil level indicator tube. You should first disconnect the coolant hose clamp before taking out the lower bolts. Disconnection of the Heated Oxygen Sensor at its wiring harness connection point becomes vital to stop any damage from occurring since you should remove the H02S wiring electrical connector. Use safety precautions to disconnect the Three Way Catalytic Converter (TWC) from its position on the exhaust manifold. The operator should raise their vehicle with proper support before loosening the bolt of the TWC bracket while putting down the TWC to let exhaust manifold studs become free. Lower the vehicle first before engine coolant temperature drops to completion of removing the exhaust manifold by unthreading the four nuts while tossing the gasket. The installation process requires using plastic manual scrapers instead of abrasive grinding discs to extract gasket material because these tools must not damage the aluminum sealing surfaces. Begin by adding a new exhaust manifold gasket then link the TWC with the exhaust manifold before restoring the H02S electrical connector. Support the vehicle once more before tightening the TWC bracket bolt then lower the car. Special attention needs to be given to mounting the heat shield last while you complete your work by inserting the oil level indicator tube into the cylinder block then installing the upper and lower bolts before securing the coolant hose bracket with its engine lifting eye in position.
