Seeking Help & Advice on Centre Guage Setup.

I would have thought water temp was the most important and therefore should go closest to the driver? I watch that more than any other gauge.

Hi Greg,

Fair comment there i guess, but when i set my gauges up, i chose the same layout as the Ford factory setup. I suppose my thinking or logic there was to fall in line with the original factory layout. Also, i was thinking of changing the gauges to give me readouts relating to other things around the car, but again, i thought it best to stay with the Ford factory formula for that original flavor if you like.

But hey, at the end of the day, people can set it up anyway they want if it suits them.

I know, by what you've already stated, that you are wanting to keep the factory sending unit (su) in place, just below the tstat neck, in the factory position, in the block.

If you install this secondary su into the threaded port next to the heater hose, on the water pump, this will read the combined coolant temp from three locations...the return from the radiator (cooled, when tstat is open), the return from the heater core (somewhat cooled, when heat is in on position) and the return via the bypass orifice during warm up of your engine. All three return coolant to the front of the water pump.

As the engine is warming up, your tstat is closed and the bypass orifice is open, sending the engine temperature coolant directly past your su. Your sending unit will get an accurate reading during this warmup time period.

When the engine is warmed up to your tstat temp (tstat open and bypass orifice closed) and the heat is "off" the coolant flow returning to the water pump (where your su would be located) will only come from the coolant which has just been cooled by passing through the radiator, therefore your reading will not reflect engine temperature. It will give you a low reading.

Thermostats open gradually/slowly over a 10°± temp range, while this is occurring (not totally open or totally closed) your su reading will be a mixture of both...get the picture? So the answer is "No," that would not be a good location to install your secondary su.

I had a similar dilemma with 2 oil pressure su's and 3 temperature su's. (mechanical aftermarket gauges, warning lights for both and a 3rd su for the electric radiator fans. Here's a few pics of the modification we made to the tstat housing. The temp warning light sender and the electric fan temp sender were installed into threaded bungs we welded to the tstat housing. The temp gauge su brass bushing is shown in the 3rd pic, in the factory su location, after the plug was removed. (su was installed a few minutes later) They all work perfect. You would need one bung for your aftermarket temp gauge.
