Installation is the reverse of removal.

If a malfunction occurs in the starting circuit, do not immediately assume that the starter is causing the problem. First, check the following items: Make sure the battery cable clamps, where they connect to the battery, are clean and tight; Check the condition of the battery cables and replace any defective ones with new parts; Test the condition of the battery, and if it does not pass all the tests, replace it with a new battery; Check the starter motor wiring and connections; Check the starter motor mounting bolts for tightness; Check the related fuses in the engine compartment fuse box and if they're blown, determine the cause and repair the circuit; Check the ignition switch circuit for correct operation; Check the starter relay; Check the operation of the Transmission Range (TR) sensor as this system must operate correctly to provide battery voltage to the starter solenoid. If the starter does not activate when the ignition switch is turned to the start position, check for battery voltage to the starter solenoid. If voltage is not available to the starter solenoid, check the fuses and starter relay in series with the starting system. If the starter turns over slowly, check the starter cranking voltage and the current draw from the battery. There are several conditions that may affect the starter cranking potential such as battery condition, terminal and cable cleanliness, and extreme cold temperatures. If the starter is receiving voltage but does not activate, remove and check the starter motor assembly on the bench. In some rare cases, the engine may be seized, so be sure to try and rotate the crankshaft pulley before proceeding. With the starter assembly mounted in a vise on the bench, install jumper cables from a test battery to the starter and observe the solenoid plunger, shift lever and overrunning clutch. If there is no movement but the solenoid clicks, the solenoid and/or the starter motor is defective. If the solenoid plunger extends and rotates the pinion drive, the starter assembly is operating properly.
