Which COOLANT Sensor??
My analog coolant temp gauge reads zero. I'm guessing it needs replacement.
Where is the coolant temperature sensor that drives the analog gauge in the dashboard? my digital coolant temp gauge works fine. I'm told there is another sensor that drives the analog gauge.
I know there is a sensor under the water pump. is that the one that drives the digital display or the analog (Pointer ) one?
Thanks in advance!

Coolant Temp
Thanks for the replies. it looks like it's in a hot place, but not too hard to get to. Looks like its between cylinders 6 and 8. Maybe a deep 19 MM or so socket.
The sensor I just bought has two terminals, so it looks like another trip to the parts store is in order.
I just got this Vette, and it's on my list of things to fix along with wheel bearings, etc. I see busted knuckles....

Coolant temp sensor
OOPs!
Mine is a '92 LT1.
Somehow I thought the model year was over there in my profile area.
Maybe I can drain some of the coolant and remove the offending sensor and take it with me to the parts store.
I'm thankful I don't have to remove a sensor right over my Optispark.
This might be a good time to change the coolant, too.
Today i turned a 1 hour headlight motor fix into a 3 hour job by not paying attention to details. It would be nice to make the sensor change no more complicated than it needs to be!!
Thanks!

Coolant loss is minimal when the analog sensor is removed.
If you decide to change coolant, you should consider removing/replacing the two knock sensor located in the bottom of
the block. Flushing the block without removing the sensors will not
clear the debris from the bottom of the block.
Try to stay clear of the coolant flow when removing the knock sensors. If the '92 coolant has never been changed, it can
be pretty nasty coming out of the 'sump'

I'm sure you're way past this, but the connector is attached to your sender correct?
I'm not sure if your 92 is the same as my 91, but on my car the connector that attaches to the sender is very easy to knock off. I've inadvertently knocked mine off many times while working under the hood on that side.

Seabright was kind enough to provide a picture that shows exactly where it is, so I'll reach down and try to press it on harder.
There are a couple of projects ahead of it, but I'll definitely get down to business on this sensor within the next week or two.
(I can't stand the idea of having a gauge that doesn't register, even if the digital readout is accurate).
Thanks (to all) for the great suggestions!

Hey! It's worth a look. I just got this car, so I didn't do it, but I'd rather check out your theory before buying a new sensor.
