What size is the temperature sensor on a SBC?
As a seasoned auto service provider, I often encounter questions about various components of vehicles, including the temperature sensor on a Small Block Chevy (SBC). This article aims to provide a comprehensive overview of the size and specifications of the temperature sensor used in SBC engines, which is crucial for maintaining optimal engine performance.
What is a Temperature Sensor?
The temperature sensor in an SBC plays a vital role in monitoring the engine's coolant temperature. This information is essential for the engine control unit (ECU) to adjust fuel injection and ignition timing, ensuring efficient engine operation and preventing overheating.
Size Specifications of the SBC Temperature Sensor
The temperature sensor for a Small Block Chevy typically has the following size specifications:
- Thread Size: The most common thread size for SBC temperature sensors is 1/2 inch NPT (National Pipe Thread).
- Length: The length of the sensor can vary, but it generally ranges from 1.5 to 2 inches.
- Wiring Connector: The sensor usually features a two-pin connector for easy installation and compatibility with the vehicle's wiring harness.
Importance of Choosing the Right Sensor
Using the correct temperature sensor is crucial for accurate readings and optimal engine performance. An incorrect sensor can lead to poor engine management, resulting in issues such as:
- Overheating due to inaccurate temperature readings.
- Poor fuel economy caused by improper fuel mixture adjustments.
- Increased emissions due to inefficient combustion.
Conclusion
In summary, understanding the size and specifications of the temperature sensor on a Small Block Chevy is essential for any car enthusiast or mechanic. By ensuring you have the right sensor, you can maintain your engine's performance and longevity.

Frequently Asked Questions
What are the symptoms of a faulty coolant temperature sensor?
Check Engine Light alert on dashboard. Rough engine sound while idling. Limited performance (caused by ECU miscalculating fuel rich mixture) Poor fuel economy.
Where is the temperature sensor gauge?
Most of the time it is close to the thermostat of the cooling system, or in some cases even inside of it. Note: Some engines may actually have a pair of sensors—one sending information from the engine to the control unit, the other sending information from the control unit to the dash.
Where is the coolant temperature sensor on a small block 350?
This is what the temp sensor looks like, it is either in the middle of the right cylender head, up on the intake manifold or mounter in the right side of the radiator side tank.
How many wires do temperature sensors typically have?
These devices measure temperature by sensing the change in electrical resistance of a material as its temperature changes. RTD probes come in a variety of configurations, including 2-wire, 3-wire, and 4-wire models.
What is the normal water temperature for a Chevy 350?
As long as the timing is correct and you have no restrictions in your cooling system and the cooling fan is working properly the average temp for the 350 chevy is 190-210. If you are running a 195 t-stat your engine will always run in this area.
Where is the temperature sensor on a 400 SBC?
drivers side head
The temp sensor should be in the drivers side head between cylinders 1 and 3. If the passenger side head has a sensor in it, the head may have been replaced at some point and they used a drivers side head.
What size thread is a LS temp sensor?
The 12mm male threads are also the correct metric threads for an LSX engine. This Chevy LS Engine coolant temp sensor adapter is manufactured from brass and a copper crush washer is included to ensure a leak-free seal.
How do I know if my engine temperature sensor is bad?
One of the very first indications that you might have a faulty coolant temperature sensor is when you notice a drop to your fuel economy. The reason this happens is as follows: The faulty sensor might send a wrong signal to the computer, leading to a miscalculation in the engine timing and fuel calculation.
What size thread is the GM intake air temperature sensor?
3/8" -
Thread Size: 3/8" - 18 NPTF.
What size thread is a GM temperature sensor?
Thread: Thread size of GM IAT sensor??
It is 3/8 NPT which is a tapered thread. You have to run the tap deep enough for the sensor to screw in.
