Where is the tempature sensor located
« on: June 15, 2009, 12:24:03 pm »
Hey guys. Now that the oil gauge is working agin, I thought I would go after the tempature gauge, since that is not working as well.

I figure before I ask noob questions like "what makes it work" I thought I would apply some of my previous knowledge to the problem.
 I assume that Ill be needing a new "tempature sensor unit" or something that reads the tempature of the engine and sends it to the gauge.

Can someone tell me where this sensor is located please so I can look for it myself and fix/replace it.

ok thanks,
Pete

If it's a small block it'll be on the drivers side head. It's called a temperature sending unit. The sensor is for the computer.

On the side of the driver side head, between the exhaust ports for cyl #1 and #3.

Wonder why they don't just use the same exact sensor? Make things easier...

Because they operate differently and have different resistance values. The NTC sensor is a negative coefficient thermistor.
