Straight Screw Plug with Head

About this product

The Straight Screw Plug with Head (#90341-10021) is an essential component in various Toyota auto systems such as the Drive-Chassis Transaxle Assy(Hev or Bev or Fcev) system and the Drive-Chassis Transmission Case & Oil Pan (Automatic Transmission) system. This part plays a key role in sealing off access points in these systems, ensuring that fluid or air does not escape or intrude into the systems during operation. It achieves this by fitting securely inside the system's components, creating a tight seal through the use of threads that match perfectly with those of the system. Periodic replacement of this plug is crucial as an old or damaged plug can compromise the integrity of the whole system, leading to fluid or air leaks that can significantly reduce the efficiency of the system's operation. Additionally, when the plug fails to seal correctly, it may also expose the system to external contaminants that can cause damage over time. Genuine parts from Toyota are recommended for optimal compatibility with your vehicle, and they are backed by Toyota's genuine parts warranty. The Straight Screw Plug with Head (#90341-10021) contributes significantly to the overall efficiency and safety of the auto systems in which it is installed, making it a vital component of your vehicle's operation.
