What size thread is a Ford O2 sensor?
The standard thread size for a Ford O2 sensor is M18 x 1.5. This means the sensor has a diameter of 18 millimeters and a thread pitch of 1.5 millimeters per thread.
Detailed Explanation
The oxygen (O2) sensor is a critical component in the exhaust system of a Ford vehicle. It monitors the air-fuel ratio in the engine and sends this information to the vehicle's computer, which then adjusts the fuel mixture accordingly. The thread size of the O2 sensor is an important specification, as it needs to properly fit the threaded hole in the exhaust system.
Ford O2 sensors typically use the M18 x 1.5 thread size. This is a metric thread standard, where the "M18" refers to the outer diameter of 18 millimeters, and the "1.5" refers to the thread pitch, or the distance between each thread, which is 1.5 millimeters.
Using the correct thread size is important for a proper seal and secure installation of the O2 sensor. Attempting to install an O2 sensor with the wrong thread size could result in a loose fit, exhaust leaks, and potential damage to the sensor or the vehicle's exhaust system.
Verifying the Thread Size
To confirm the thread size of a Ford O2 sensor, you can:
- Check the sensor itself for any markings or specifications indicating the thread size.
- Refer to the vehicle's repair manual or parts catalog, which will list the correct O2 sensor part number and thread size.
- Measure the threaded portion of the O2 sensor using a caliper or thread gauge to determine the diameter and pitch.
Knowing the correct thread size is essential when replacing a Ford O2 sensor to ensure a proper and secure installation.
Do you put anything on oxygen sensor threads?
Treat the threads of the new oxygen sensor by applying an even layer of anti-seize lubricant (FIGURE 3). Walker sensors include this component to insure a quality installation.
How do you fix O2 sensor threads?
If you want you can wear welding gloves protect your hands and arms from burns. I like to work the tap in and out of the threads as the pipe cools to insure fitment of the new o2. Sensor.
What size tap is an O2 sensor?
Your thread size is 18mm x 1.5. KD tools makes a tap special for this purpose, and it works great.
Are all Ford O2 sensors the same size?
Any that you find on a Ford truck should be the same size. They're either 7/8 or 22mm depending on who you ask.
What is the most common O2 sensor size?
22mm
7/8ths is the Imperial equivalent of decimal 22mm. O2 sensors are all pretty much standard in size.
Are all 02 sensors the same thread size?
There is no overall standard here although M18x1. 5 appears to be relatively common. I recommend that you pick the O2 sensor you intend to use for this application and then weld on the bung for that particular model.
What size mm is an O2 sensor?
22 mm
In some cases, your O2 sensor may require a smaller size tool than the standard 7/8” or 22 mm. Locate the sensor along the vehicles exhaust system and pre-treat the area with a spray lubricant.
What is the thread pitch for an O2 sensor?
*Most cars and older motorcycle oxygen sensor's utilize the M18x1. 5mm thread pitch. Newer motorcycles use a smaller O2 sensor with a M12x1. 25mm thread pitch.
Are all O2 sensors 22mm?
【Product Size】The sensor socket has a standard 6-point shape. 7/8 inch (22 millimeter) hex fits almost all oxygen sensors.
Are O2 sensors standard size?
7/8ths is the Imperial equivalent of decimal 22mm. O2 sensors are all pretty much standard in size.
