On a 53 ford flathead v/8 with dual temp. sensors,what would you recommend as an after market temp. gauge, keeping in mind a reasonable price?
In my '49 tudor I found the stock senders weren't giving me too accurate of readings so I installed a mech SW temp gauge under the dash as extra assurance, worked great.
I don't believe you can hook up two senders to the same gauge. Would be great to have an aftermarket gauge that reads each bank on one face.
When Ford used two senders, one had one terminal and the other had two. The sender that was hotter fed the gauge to get the hotter readng. A better way is to use 2 single pole senders wired to a switch that can be switched from one sender to the other thus reading left head or right head. The passenger side normally runs hotter than the drivers side, so that is where you normally install a mechanical gauge unless you want two mechanical gauges. As far as accuracy, I check all my gauges and then check coolant temps at gauge pickup with laser.
Has something to do with the design, I knew once but forgot. All of my flatheads run 5 to 10 degrees hotter on the right.
