How to Remove the Starter on a 1990 Chevy Pickupby Christian Killian
You may need to remove the starter motor from you Chevy pickup if it is grinding or dragging, in order to test it. The starter motor is located on the passenger side of the truck, directly below the engine block at the back of the engine. New starter motors are available from most auto parts stores; if you remove your starter first, the auto parts store will often bench test your starter for free to help you determine whether it is defective.
Open the hood of your Chevy and locate the battery. Remove the negative battery cable from the battery after loosening the adjustment bolt on the battery cable end with a wrench.
Raise the front of the truck with a jack so you can comfortably work under it. Position a set of jack stands under the frame rails of the truck, then lower the jack so the truck is resting on the jack stands.
Locate the starter on the passenger side of the engine, then find the two electrical connectors on the rear of the starter solenoid on the top of the starter. Remove the two nuts securing the connectors to the solenoid, using a socket and ratchet; then push the wires aside.
Move to the front of the starter and locate the two large bolts that run through the starter from the bottom and into the engine block. These are the starter retaining bolts. Remove the retaining bolts with a socket and ratchet.
Carefully lower the starter motor down from the engine compartment. Remove the starter from under the truck.
