Unhappy Crazy Temp Gauge!

Ok, my irv2 friends, what's causing this? Short in wiring to gauge or temp sensor? I know it's not overheating, when it does decide to 'settle' for a few seconds, it reads a normal temp. Give it a few seconds to get the the crazy spin all the way around parts. I think it's possessed! Hope this comes out right...
Thx for any input on this.

Please don't take this the wrong way...but that is the funniest thing I have ever seen!!!!

OK, back to earth....You either have a short in the cable or the sending unit is bad. You may want to unplug the wire from the sending unit and see what happens

vtbigdog, I agree, it is funny to watch, I told ya it was possessed! I've been looking all over the place, to find a diagram to show me where to look for the sensor, I know it's supposed to be around a radiator hose somewhere, but can't find it, need a picture! lol. 400 small block, 6.6.

Forgot to mention, now it's stuck over past the 260 mark and hasn't dropped yet! Been about 4 hrs. since shut off.

Too funny!

It looks like you have a short circuit somewhere. It's been a while since I worked on a small block, but if I remember right the temp sensor can be located either on top of the intake manifold or on the driver's side head. Depending on the year, they put it in a couple of different places. I have also seen them on the side of the block.

Try to disconnect it without moving/disturbing the wire. If it still reads high, then the short is in the wire, otherwise it's probably the sensor. Check the resistance from the sensor connector to the block. If it reads close to 0 ohms when the engine is cold then the sensor is bad.

The good news is that the sensor is about $10. There are two types of sensors depending on if you have a gauge or light. Make sure you get the right type. When installing it wrap the threads with teflon tape and install it. Top off the coolant and check for leaks and gauge operation as the engine warms up.

If it's the wire, sometimes it hits the exhaust manifold and the insulation burns off and creates a short. Just replace the bad part of the wire and reroute it away from heat and sharp edges.
