2004 Toyota Highlander Starter Location: A Step-by-Step Guide

For the 2004-2007 Toyota Highlander models, specifically those equipped with the L4 2.4L engine, the starter is found at the top of the transmission.

Although it might seem daunting at first, accessing the starter is manageable when we follow the right steps.

Typically, the starter is not immediately visible upon opening the hood, which is why understanding its position relative to the battery tray and the radiator support becomes crucial.

In our experience, the most efficient approach to reach the starter involves removing the battery and the battery mount to clear the work area. This affords us not only better visibility but also more space to work with hand tools.

It is essential to proceed with caution during this process and handle all electrical components carefully to avoid any unwanted electrical hazards or damage to the vehicle’s components.
