Whether your 1990 Toyota 4Runner is equipped with the 4-cylinder or 6-cylinder engine, replacing the starter requires the same procedure, as the starter is located in the same place in both cases. A failing starter may drag, grind, click or just fail to function at all. In any of these cases, removing the starter from the truck will allow you to have it tested to confirm that it is indeed malfunctioning. Replacement starter motors for the 4Runner are available through the dealer or through most auto parts stores.

Tools Used[edit]

Wrench set
Socket set
Torque wrench

Change a Starter[edit]

  • Open the hood of the truck and loosen the clamp bolt on the negative battery cable end, using a wrench. Wiggle the cable end and pull it off the battery, then isolate it away from the battery so that it does not make contact with either terminal while you are working.
  • Locate the starter under the passenger's side of the engine. You will not need to raise the truck, as there is plenty of room under it to work. Chock the tires so that the truck cannot roll while you are under it.
  • Remove the retaining nut from the battery cable, where it meets the starter solenoid, using a 12-millimeter wrench, then remove the cable from the terminal. Release the locking tab on the electrical connector on the rear of the solenoid, then pull the connector loose.
  • Remove the lower mounting bolt from the starter, using a socket and ratchet, then remove the upper bolt while supporting the starter motor. Lower the starter out of the engine compartment, then position the new starter in place.
  • Install the upper mounting bolt into the starter, but leave it loose for now. Thread the lower bolt in place, then tighten both mounting bolts, torquing them to 29 foot-pounds, using a torque wrench.
  • Push the electrical connection into the socket on the rear of the starter solenoid until it locks in place. Place the battery cable on the stud on the starter and install the retaining nut, tightening it with a wrench.
  • Move up to the engine compartment and install the negative battery cable on the battery, tightening the clamp bolt on the cable end with a wrench to secure the cable to the battery. Start the engine to verify that the repair was successful.
