How to replace starter on Ford & Mercury?

The procedure is similar for Ford and Mercury car models.


Starter
REMOVAL & INSTALLATION PROCEDURE
TESTING THE STARTER.

The instructions are as follows :---


Removal & Installation



Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
  1. Disconnect the negative battery cable.
  2. Remove the air cleaner outlet pipe.
  3. Remove the transaxle roll restrictor bolts and the cross brace assembly.
  4. Remove the starter cover.
  5. Disconnect the starter electrical connectors.
  6. Remove the starter bolts.
  7. Remove the starter from the vehicle.
To install:

  1. Position the starter in the vehicle.
  2. Install the bolts. Tighten to 18 ft. lbs. (25 Nm).
  3. Connect the starter electrical connectors.
  4. Install the starter cover.
  5. Install the cross brace assembly and transaxle roll restrictor bolts.
  6. Install the air cleaner outlet pipe.
  7. Connect the negative battery cable.

Testing



Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009

WARNING
Always disconnect the battery ground cable at the battery before disconnecting the starter motor battery terminal lead. If a tool is shorted at the starter motor battery terminal, the tool can quickly heat enough to cause a skin burn. Failure to follow this instruction may result in serious personal injury.


NOTE
Always make the 73III Automotive Meter connections at the component terminal rather than at the wiring end connector. Making a connection at the wiring end connector could result in false readings because the meter will not pick up a high resistance between the wiring connector and the component.

Motor Feed Circuit
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
  1. Make sure the battery is fully charged; carry out a battery load test.
  2. Connect a remote starter switch between the starter solenoid S-terminal and the battery positive (+) terminal.
  3. Connect the 73III Automotive Meter positive lead to the battery positive (+) post. Connect the negative lead to the starter solenoid M-terminal.

  4. Engage the remote starter switch. Read and record the voltage. The voltage reading should be 0.5 volt or less.
  5. If the voltage reading is 0.5 volt or less, go to the Starter Motor - Ground Circuit component test.
  6. If the voltage reading is greater than 0.5 volt, this is an indication of excessive resistance in the connections, the positive battery cable or in the starter solenoid. Move the 73III Automotive Meter negative lead to the starter solenoid B-terminal and repeat the test. If the voltage reading at the B-terminal is lower than 0.5 volt, the concern is either in the connections at the starter solenoid or in the solenoid contacts.

  7. Remove the cables from solenoid B-, S- and M-terminals. Clean the cables and connections and reinstall the cables to the correct terminals. Repeat Steps 3 through 6. If the voltage drop reading is still greater than 0.5 volt when checked at the M-terminal or less than 0.5 volt when checked at the B-terminal, the concern is in the solenoid contacts. Install a new starter motor.
  8. If the voltage reading taken at the solenoid B-terminal is still greater than 0.5 volt after cleaning the cables and connections at the solenoid, the concern is either in the positive (+) battery cable connection or in the positive battery cable itself.
  9. Clean the positive (+) battery cable connection. If this does not solve the problem, install a new positive battery cable.
Motor Ground Circuit
Specific to:
Ford Taurus 2008-2009
Mercury Sable 2008-2009
A slow cranking condition can be caused by resistance in the ground or return portion of the cranking circuit. Check the voltage drop in the ground circuit as follows:
  1. Connect the 73III Automotive Meter positive lead to the starter motor housing (the connection must be clean and free of rust or grease). Connect the negative lead to the negative (-) battery terminal.
  2. Engage the remote starter switch and crank the engine. Read and record the voltage reading. The reading should be 0.5 volt or less.
  3. If the voltage drop is more than 0.5 volt, clean the negative cable connections at the battery, the body ground connections and the starter ground connection. Retest.
  4. If the voltage drop is greater than 0.5 volt, install a new cable. If the voltage reading is less than 0.5 volt and the engine still cranks slowly, install a new starter motor.

This details will help.
Thanks.
