How to Change a Starter on a 1991 Toyota 4WD Pickup
The 1991 Toyota four-wheel drive pickup has a starter motor on the passenger side of the engine. Replacing the starter motor on the Toyota four-wheel drive truck may become necessary if your starter starts grinding or dragging. Because the starter motor is so low on the engine, it can be affected by water and external elements such as mud or road debris. A replacement starter motor for your Toyota is available from Toyota or any auto parts store.
- Moderately Easy
- Wrench set
- Jack stands
- Socket set
Open the hood of your Toyota pickup and locate the negative battery cable on the battery. Remove the retaining bolt from the cable end with a wrench and remove the cable from the battery. Isolate it from the battery while you work on the electrical cables of the starting system.
Raise the front end of the truck with a jack and support the truck on a set of jack stands. Some four-wheel drive models are high enough that you may be able to work under it without the jack.
Locate the starter motor from under the passenger side of the engine compartment. There are two electrical connections on the starter to deal with. The first is a large single wire that attaches to the starter by sliding onto a stud type terminal. This is the "B" terminal. Loosen the retaining nut with a socket and ratchet then remove the cable from the starter. The second is the "S" terminal and it has a smaller wire with a push in style connector on the end. Release the locking tab by squeezing it and pull the connector out.
Locate the two mounting bolts at the front of the starter and remove them from the back transmission side of the bell housing using a socket and ratchet. Remove the old starter from the truck and discard it. Install the new starter in the truck by placing the nose cone of the starter into the hole in the bell housing.
Install the two mounting bolts into the starter and tighten them with a socket and ratchet. Connect the two wiring harness connectors to the terminals on the starter, pushing the wire to the "S" terminal in first. Connect the second wire to the "B" terminal followed by the retaining nut, then tighten the nut with a socket and ratchet.
Lift the truck off the jack stands with a jack, remove the stands from under the truck and lower the jack, setting the truck back on the ground. Connect the negative battery cable end to the negative battery terminal. Install the retaining bolt for the negative battery cable and tighten it with a wrench.
Close the hood on your Toyota truck. Test the repair by starting the truck to ensure the starter works correctly.
