To remove and replace the starter, please adhere to these steps, Commence by turning off the battery at its negative terminal then lift your car up and support it using jack stands. Remove the solenoid heat shield from the solenoid for 4.3L V6 (2014 and earlier), 5.0L, 5.7L, and 7.4L V8 engines and disconnect the electrical leads from both terminals of the solenoid. Proceed to remove the starter solenoid's nut fastening
Battery Cable as well as switch lead to the stud terminals, thereafter disentangling both wires from their respective terminals. Leave them connected if necessary until such time when the starter is out of transmission bellhousing. Remove shims (if equipped) and then starter mounting bolts while making sure that you hold up the starter not to be suspended by wiring harnesses. If you're replacing the starter on a 7.4L V8 engine, take off heat shield from solenoid and put it on a new starter assembly before installing it back into place. Lastly, installation is just a reverse order of removal procedure but make sure that you tighten them with required torque specification for these mounting bolts on starters. For 4.3L V6 (2018 and later), 4.8L, 5.3L, and 6.0L V8 engines start by removing right bell-housing cover retaining bolt; repositioning oil cooler if needed; take out sensor connector; remove two bolts holding down cooler tube bracket in order to permit movement of bracket away from bell housing; after pushing tube upwards in order stabilize position so that it does not flex under pressure during removal or installation processes now slide heat sink onto transmission pipe itself allowing ample clearance between attachment points thus ensuring any movement does not cause undue stress upon components like pump housing or filter housing etc." Remove starter mounting bolts and disconnect the electrical connector from oil level sensor. Slide the starter towards the front of car until it clears transmission bell housing while supporting it to avoid damaging anything. After disconnecting the battery cable and electrical connector from the starter solenoid, go ahead with installation in reverse order but make sure that you tighten them as required for these mounting bolts on starters.
