Automotive starter motors commonly fail after many years of use. If your S-10's original starter has begun to drag or make noise, remove it from the truck and have it bench tested to determine if a new starter is needed. The starter motor in the Chevy S-10 pickup with a 4.3-litre engine is located on the passenger side of the engine; the starter on an S-10 with a 2.2-litre engine is located on the driver side. Regardless of which engine your S-10 has, the starter mounts the same and uses the same electrical connections on either engine, so remove either one from your truck using the exact same steps.

Open the S-10's bonnet and locate the battery's negative cable. Remove the bolt in the battery cable end with a socket and ratchet, then remove the cable from the battery. Set it aside for now.
Place a jack under the front jack point or points of your S-10 and lift the truck off the ground. Install a set of jack stands under the frame rail, then lower the jack, allowing the truck to settle securely on the jack stands. Slide under the S-10.
Locate the starter under the back portion of the engine, on the driver side on the 2.2-litre engine or on the passenger side if your S-10 has the 4.3-litre engine. The starter motor is a large, cylindrical part. It mounts to the engine block with the nose of the starter protruding into the bell housing. It has a smaller cylinder on top of it, the starter solenoid, that has two electrical connectors on it.
Remove the electrical connectors from the back of the starter solenoid with a socket and ratchet. Both connectors are stud-and-nut-type terminals, and the wires will slide right off the stud once the retaining nut is removed.
Move to the front of the starter and locate the two mounting bolts. The two bolts run up into the starter from the bottom and thread into the engine block. Remove the bolts, one at a time, with a socket and ratchet.
Lower the starter from the engine compartment and remove it from under the truck.

- Hold the starter with one hand as you remove the final bolt to keep the starter from falling.
