What size thread is the GM intake air temperature sensor?
The GM intake air temperature sensor typically uses an M12 x 1.5 thread size. This sensor is responsible for measuring the temperature of the air entering the engine, which is an important parameter for the engine control module to optimize fuel delivery and ignition timing.
Detailed Explanation
The intake air temperature (IAT) sensor is a critical component in the engine management system of General Motors (GM) vehicles. This sensor is mounted in the intake manifold or air intake duct and measures the temperature of the air entering the engine. The engine control module (ECM) uses this information to adjust the fuel injection and ignition timing to optimize engine performance and efficiency.
The IAT sensor is threaded into the intake system to ensure a secure and sealed connection. The most common thread size used for GM IAT sensors is M12 x 1.5. This means the sensor has a diameter of 12 millimeters and a thread pitch of 1.5 millimeters per thread.
- M12: The sensor diameter is 12 millimeters.
- x 1.5: The thread pitch is 1.5 millimeters per thread.
This thread size provides a tight, leak-free fit while also allowing the sensor to be easily installed and removed for service or replacement. The M12 x 1.5 thread is a common standard used not only for IAT sensors but also other engine sensors and components across the GM product line.
It's important to use the correct replacement IAT sensor with the proper thread size to ensure a proper fit and seal in the intake system. Using the wrong size sensor could result in air leaks, sensor failure, or other issues that could impact engine performance and fuel economy.
What size thread is the intake air temperature sensor?
It is 3/8 NPT which is a tapered thread.
What are the threads on the IAT sensor?
The sensor has 3/8" NPT threads and a threaded weld on bung. The bung has a 7/8" step and 1" main body diameter.
What size thread is a LS temp sensor?
Factory LS cylinder heads are machined with metric M12-1.5 coolant sensor ports, so your factory Small Block Chevy sensor won't thread in to them. This adapter allows you to keep your original sensors and integrate them into your swapped LS engine.
What size thread is a NOx sensor?
M20 x 1.5 thread
Applications include: DAF & Mercedes-Benz NOx sensors. For use on any M20 x 1.5 thread. Total length: 48mm.
What size thread is a GM air temperature sensor?
3/8" - 18 NPTF
Thread Size: 3/8" - 18 NPTF.
What size thread is a GM IAT sensor?
3/8" - 18
Thread Size: 3/8" - 18 NPTF.
What size thread is a GM temperature sensor?
Almost any GM sensor that screws into a cast iron head, intake or block uses National Pipe Thread (NPT), except for oil taps. The OEM heads, as stated above, are usually 1/2 inch NPT.
What is the thread size on a GM oxygen sensor?
M18 X 1.5
The oxygen sensor thread size is M18 X 1.5. There is a special tool for O2 sensors thread restore purposes. Check out this LINK . Let me know if you need more assistance.
What size thread is a GM intake air temperature sensor?
Thread Size: 3/8" - 18 NPTF.
Are all O2 sensors the same thread size?
There is no overall standard here although M18x1. 5 appears to be relatively common.
