To make the connection to a 5.3 oil pressure sensor, you will need a 3/8″ socket. The 5.3 oil pressure sensor is a 3/8″ NPT (national pipe thread) item, which means it has a 3/8″ inner diameter. Therefore, any socket with a 3/8″ diameter will suffice.
Check the specifications of the socket you’re using to check it fits the 3/8″ diameter of the 5.3 oil pressure sensor to ensure you have the correct size socket. Thus, you can be certain that you will not encounter any issues when attaching the sensor.
To ensure a secure fit and a tight seal, you must also utilize a socket with deep grooves designed to support the oil pressure sensor. A socket with shallow grooves will not be able to give sufficient grip to hold the sensor in place, therefore look for one with deeper grooves.
Remember that size matters when it comes to the 5.3 oil pressure sensor. Obtain the correct size socket, and you will be set to go.
