Dual Westach Temp Gauge - for what ??

[SteveW]

Greetings from Southern California

I came upon this gauge in Bob Cook's (RIP) collection of gadgets.

Any idea what he intended to monitor ?? Transmission pan and a thermocouple somewhere ? Where ?? Cooler inlet?? Outlet ??

Thanks for you ideas.

That Westach dual temp indicator was typically mounted in the instrument panel between the Speedo and the instrument cluster. Just up a little in that open area. You can select you want to monitor and it should have the type of thermocouple to use on the back. This is not a cheap gauge. They sell today at about $200 give or take. A number of years back there were several GMCers that put them in the dash. There was an article somewhere that I remember that I cannot find, maybe someone else has a good memory.

Thanks JR !!

I already have the one of which you speak... between the Speedo and the instrument cluster. It displays RPM and Vacuum. Works GREAT.

Having thought about it since my original post - I’m more convinced that the gauge is intended for transmission temperatures.

PAN is most likely the transmission pan and T/C is a thermocouple probably at the outlet of the cooler.

And... maybe T/C is Transmission Cooler !!

Thanks again,
SW

Hey Steve. I have the same tach/vac gauge between the two large dash gauges. Love the thing.

The dual gauge you've got would be perfect for transmission pan and final drive.
