  Q: How do you remove and replace the starter motor?

  A: 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.

  Q: How to diagnose and check a malfunction in the starting circuit and Starter on Chevrolet Express?

  A: In case of any suspect on starting circuit malfunction, do not immediately attribute this to the starter that could be faulty. Instead, carry out a step by step inspection of various parts and connections until you find out the main cause. Make sure that Battery Cable clamps are clean and tightly fastened at the battery terminals. Inspect condition of battery cables and change those that have malfunctions. Test the condition of your battery, where if it fails any tests, replace it with a new one. Look at wiring and connections related to the Starter. Ensure that all Starter mounting bolts are tight. Check for any blown fuses on relevant fuses in engine compartment fuse box and exchange them accordingly as well as addressing other issues associated with them. Ensure that ignition switch circuit is functioning properly. Examine the starter relay for any potential problem areas. Also assess if Park/Neutral Position (PNP) switch has been adjusted properly or not. When you turn the key to start but there is no sound from your engine, check for 12 volts at starter solenoid's positive terminal while using 12 volt test light or voltmeter and have an assistant start expect brightness with test light or voltage readings to show battery presence when turned to start position with ignition switch on. Failure of voltage indicates problems with the fuses or starter relay in the starting system itself. If voltage is present but there is no action from the solenoid Starter; remove it for bench testing purposes. When cranking over slow, perform tests for starter cranking voltage and current draw ensuring that battery voltage does not fall below 9.6 volts as well as not exceeding 160 amps typicaly for 30 seconds continuously.If they do not meet these specifications then consider purchasing a new one because such cannot be used.Otherwise ensure warmness between battery terminals as well as cables which should be free from corrosion during extreme cold conditions by heating block and battery. If there is a voltage supply to the starter but it does not work, connect it to a test battery using positive and negative jumpers in order to observe movement of plunger, shift lever and overrunning clutch for solenoid S terminal when battery voltage is applied. In case the pinion drive comes out without turning around, then the solenoid is good but the Starter is faulty. If there is no motion but solenoid click then either solenoids or Starters are bad. The starting system will be fine as long as solenoid plunger makes pinion drive rotate.
