Flat Head Water Temp Gauge...

What do ya'll run 1 gauge or 2, and is either way better than the other??. My stock gauge isnt working so I want to put one in, but I dont know if I should run 1 or 2. Thanks,Mike

 

I run 2 SW 2 5/8 gauges. only went thru 4 to get 2 good ones.
Good luck

 

me two im on my 3rd temp gauge

 

I have the original gauge on one side, and a second aftermarket gauge on the other.

 

I used to run two, only because the bolck didnt have a common water passsage. It didnt realy prove anything. So now just run one autometer gauge. In the original set up apparently the second sender wasnt a sender it was just a thermal switch to actuate the sender. If you want you could run one gauge and plug the second sender hole with a screw in moon type temp gauge.

 

Kiwi 4d is correct about the original set up. One side gives you an actual temperature read out and the other gives just an overtemp indication. Since the left and right cylinder banks are independent of each other the only way you can get an overall temp reading with one gauge is if the temp bulb was in the top of the radiator tank and of couse it wouldn't work if the water level was too low. Only other way to know for sure is two separate temp guages in each bank. To repair the original system for one gauge would not be too dificult. I see NOS and used gauges an the E-pay as well as the single and twin trminal temp bulbs. If converted to 12-volt, a voltage dropping device would be required.

After chasing an overheating problem that turned out to be a bad sending unit I installed two mechanical gauges and made a mount for under the dash. Engine never goes over 180°.

 

I have an intermittent stock one, and an aftermarket SW under the dash. The SW only monitors one side, but I kinda figure if one side gets way hotter than the other, you were gonna have issues either way.

 

I'm planning 2 mechanical temp gauges, one for each side.

I have been doing 2 in my projects. I have new cheezy ones on my test stand but get old ones out of trucks and on the 'bay, check em with a meat thermometer.

 

Sounds good, thanks guys.

 

What about early looking electric gauges and 2 sending units? could toggle between senders or connect them both, it would read the hightest one so no worries.

 

Sounds like a good option, thanks.

 

I run 2 classic instruments temp gauges. Never had a problem with them. Sure is nice knowing which thermostat is sticking!
