Bracket over fuel rails on '98 Town Car

Hi,

I am replacing the intake manifold on my '98 Town Car. The problem: There is a bracket towards the back of the engine bay that comes over the fuel rails on the driver's side. This bracket was holding the throttle cables behind the throttle body. I cannot get this off. I found one nut on the back of the engine (it might have been attached to the valve cover, it was hard to see) and took it off, but the bracket still won't budge. This has to come off in order to get the fuel rails off and to take the intake manifold off. Do you guys have any ideas?

What size wrench do I need to remove the rear bolt on the bracket over the fues rail replacing the intake manifold?


I'm sorry but I do not know what size wrench you need for that. You might call a Lincoln dealership and see if they know. A workshop manual might also have that information. Good luck!

Starter needs to be replaced. Need instruction procedure for a do it yourselfer.


Hi, I have pasted the procedure from autozone.com below. Because this requires removal of the intake manifold, please be as sure as possible that your starter needs replacement. If you have any doubt, please let me know what your symptoms are and what troubleshooting you have done that led you to believe your starter is bad. Also, if you have any questions about the procedure below, please let me know. Thanks for using FixYa.


Removal & Installation


Disconnect the Negative battery cable


Relieve the fuel system pressure (you can do this by placing a rag over the schrader valve on the fuel rail and pressing in the valve stem--just be careful not to spray fuel on your eyes).


Drain the cooling system.


Remove or disconnect the following:


  • Intake manifold heat shield
  • Sight shield
  • Coil module connectors from the coil modules located on the valve covers
  • Positive Crankcase Ventilation (PCV) hose and valve from the valve cover
  • Fuel regulator vacuum tube
  • Vacuum tubes from the AIR solenoid
