Topic: Mechancial Temp Gauge Sending Unit Location

  I've searched the forum for this but was unable to find any references. For those of you that have installed a mechanical temp gauge, particularly on '42-'48s, where did you mount the sending unit? Did you simply eliminate one of the original sending units, install it there and then let the original dash gauge give you the reading from the other side? Or did you leave the original gauge and two sending units alone and install the additional gauge sending unit elsewhere and if so where, how and any problems/additional considerations?

Giving consideration to doing a temporary gauge install to get a personal calibration on the original gauge's while-driving readings for peace of mind prior to driving to Gettysburg from NC this coming August. Thanks in advance -

Steve

  Steve, replace the sending unit that has 2 terminals with the mechanical sending unit.

The sending unit with 2 terminals is just a overheating switch. It stays closed until the coolant reaches boiling temperatures and then opens, this makes the gauge read all the way to the right or HOT.

The sending unit with one terminal gives a variable reading that reflects the temperature of the coolant.

  Read this thread on the Ford Barn to see how I did it: http://www.fordbarn.com/forum/showthread.php?t=88541

  Thanks to you both guys - great info. Was not aware of the (not so) subtlety of the driver's side sending unit Tom - thanks for the education there.

Old Henry - thanks there as well, though I am hyper adverse to any permanent modification that may affect my interior in any way. Will likely look at a temporary adhesive Velcro installation of a simple gauge as you suggested under the dash on the left side of the steering column. Really like your idea though - if I had another original glove box enclosure would likely go this route as well. Btw - sending you a p.m. shortly on another matter.

Thanks again -

Steve

  Glove boxes come cheap - $17.00 from C&G here: http://cgfordparts.com/ufolder/cgcat.php?searchtype=Search+%23&year_choice=47&searchtextdesc=glove+box&searchnumber=43000&sp=Search+%23

As I said in my thread, the only modification made to the interior to put the gauge in the glove box was to drill a 1" hole in the back of it to pass the sender through. Otherwise, no modifications.

  Makes the install as you've proposed a no brainer for me now. Have never looked for the glove boxes so learned a bit more in the process as well. Will give this a go later this month.

Thanks again Old Henry & TomO -

  I have mine in the glove compartment also but drilled a hole the size of the gauge and slipped it through it on the right side of the box.I did not use the mounting bracket and you don't see any wires as it fits flush with the side.

  I like that idea even better than mine. Then the gauge doesn't interfere with the use of the glove box to put other things. Very good.

  From the other side of the aisle .... For preservation/visual reasons I've kept all my dash gauges active. However because they're less accurate than add-in's I added gauges to gain info and I do monitor them. I have two mechanical temp gauges - one each side + a voltage gauge (more useful than an amp gauge) + oil pressure. To minimize space usage I use the German-made illuminated 1-1/8 dia gauges with black background for easy reading. Need to say - my adult kids and G-kids love to ride at night.
