Temperature Switch #2

About this product

The Temperature Switch #2 (#89428-21010) is a key component in Toyota's Switch & Relay & Computer system, an Electrical part designed for optimal vehicle compatibility. Its main role involves monitoring and responding to changes in the coolant temperature within the engine system. When the coolant's temperature rises above or falls below a certain point, the switch triggers a response in the system - either activating the radiator fan or relaying a signal to the onboard computer. Over time, this part can become clogged or unresponsive, leading to inaccurate readings and potential overheating or under-cooling. This can result in significant engine damage. That's why it's important to periodically replace the Temperature Switch #2 (#89428-21010) with genuine Toyota parts, all of which are backed by Toyota's genuine parts warranty. By maintaining a stable and safe operating temperature, the Temperature Switch #2 (#89428-21010) plays a crucial role in ensuring the system's overall efficiency and safety.
