This short series Oxygen sensor socket is used for the removal and installation of Oxygen or Lambd...This short series Oxygen sensor socket is used for the removal and installation of Oxygen or Lambda sensors. It features a slot in the side, enabling it to be fitted over the wiring harness, and can be driven by either a 30mm spanner or 1/2"D ratchet making it ideal for both difficult access situations or for when increased torque is required to undo tight or seized sensors. Short series - length: 70mm. To fit 24mm single hex Lambda (Oxygen) sensors. The combination of open wrench and 1/2” ratchet drive allows for the application of increased torque. Can be driven by 1/2"D ratchet or 30mm spanner depending on access. A 22mm O2 sensor socket socket also available, please see Part No. 8063. Manufactured from chrome molybdenum with black phosphate finish.

Product Information
Full details
This Laser 8590 Oxygen Sensor Socket Wrench Insert is designed for automotive technicians and DIYers needing to remove and install oxygen or Lambda sensors, particularly in tight spaces. Its primary benefit is the side slot that accommodates wiring harnesses, allowing for easier access and application of increased torque. A potential caveat is its specific size fitting only 24mm single hex sensors.

FAQs
What size sensor does this socket fit?
This socket is designed specifically for 24mm single hex Lambda (Oxygen) sensors.
Can I use this socket with any ratchet?
Yes, it is compatible with any standard 1/2" drive ratchet. It can also be used with a 30mm spanner.
Why does it have a slot in the side?
The slot allows the sensor's wiring harness to pass through, enabling the socket to fit onto the sensor without needing to disconnect the wiring first.
Is this socket suitable for all oxygen sensors?
No, it is specifically designed for 24mm single hex sensors. A different size socket (like the 22mm Part No. 8063) may be required for other sensor types.
What material is the socket made from?
It is manufactured from durable chrome molybdenum steel with a black phosphate finish.
How long is the socket?
The socket has a short series length of 70mm, making it suitable for tight access areas.
Can this socket help remove very tight sensors?
Yes, the combination of the 1/2" drive ratchet option and the robust construction allows for significant torque application, which can help loosen seized sensors.
Troubleshooting
Socket does not fit the sensor
Verify that the sensor is a 24mm single hex type. If it is a different size or hex configuration, this socket will not fit. Consider the 22mm alternative (Part No. 8063) if applicable.
Difficulty applying torque
Ensure a secure fit of the ratchet or spanner onto the socket. If using a ratchet, confirm it is properly engaged. For extremely tight sensors, a longer-handled ratchet or breaker bar may be necessary, but use caution to avoid damaging the sensor or exhaust component.
Wiring harness does not fit through the slot
Ensure the harness is properly aligned with the slot. Some sensor connectors may be bulkier; try to manipulate the harness to pass through. If the connector is too large, this socket's design may not be suitable for that specific sensor.
