Temperature Gauge Installation I’ve decided to install a temp gauge using a modified upper water outlet. For those of you who have already done this, what gauge did you use and how did you route the lead from sensor to gauge without drilling a hole in the firewall ?
Many thanks - Jim |

You can run it through the instrument panel and tie wrap it to the wire leading to the generator/alternator. Or along one of the radiator braces. A link to instructions at site above. |
Re: Temperature Gauge Installation Mine runs through the terminal box, no drilling required. My gauge is currently a vintage generic brand that looks like a Steward Warner but I have a Boyce Moto Meter from the 30's I believe that works but is off by about 20 degrees so hopefully it can be calibrated or if nothing else the needle can be moved.

Re: Temperature Gauge Installation Here is how I did mine years ago. I ran the cable down along the steering column.

I installed a temp gauge using the modified water outlet that allows the temp probe to be installed from the side. Routing is as already mentioned, follow the generator wire and through the terminal box. My repro gauge is mounted under the speedometer using one of the mounts available from the vendors.
One very annoying issue is that I cannot torque the head nut that is just below the temp probe, without draining the cooling system and removing the probe. Did I mention that this is very annoying??. There isn't enough vertical clearance to use the thin walled craftsman socket with the probe installed and the special Snap-On S-8663-A tool won't fit between the nut and the side wall of the outlet. If I ever remove the outlet I will open that up a bit but until then...:( Now not all modified outlets may have this problem, and I don't really remember where I got it as it was several years ago. But it might be worth checking out before installing a modified outlet. See pictures. |

Mine has a vintage looking Stewart Warner gauge with the wings. Single gauge mount under the inst panel is from Berts. The water outlet is the type that uses a thermostat. The gauge line runs along the generator wire into the terminal box.

Re: Temperature Gauge Installation If you haven't already purchased the modified upper gooseneck, you might want to consider the Vintage Precision thermostat housing with temp probe port as an alternative (see ModelA29's picture for this). That way you get a thermostat in addition to the temperature probe. I also ran my temp probe cable through the wiring box on the firewall.

Re: Temperature Gauge Installation Wow ! Thanks for all the responses so quickly ! This is all very useful information - es[ecially about routing the electrical or capillary tubing from the engine compartment into the car.
Tom Endy - your article is great, and gives me an idea how to mount a gauge in my car. 1955cj5 - thanks for the wrench clearance note - I would not have thought of that, so thanks for the heads-up ! Jim |

I have a 270° sweep Stewart Warner gauge. I prefer the 270° sweep gauges as the numbers are farther apart and easier (for me) to read. https://live.staticflickr.com/4805/4...7c6ff024_z.jpg I routed it with the other wires and up the steering column. I wrapped it is ClassicBraid so it resembled the other wire loom. https://live.staticflickr.com/1786/4...ac65ac9f_z.jpg[/url] |
Re: Temperature Gauge Installation This is a very handy inexpensive wrench for torquing those hard to reach nuts.

Re: Temperature Gauge Installation I bought mine at Snyders. Used the water neck they sell, and the gage holder too. Went through the terminal box. Way better than my moto-meter was.

Re: Temperature Gauge Installation I just drilled and tapped the back side (facing the rear of the car) for a 1/2 inch pipe thread. Was really easy to do. In fact I was so ecstatic that I did six of them!

Taking a different approach, I bought an all-metal gauge cup from Amazon that was a perfect fit for the gauge and installed it on top of the steering column with a black hose clamp and then ran the capillary tube down the steering column. Nice, clean installation and I like the gauge up high making it easy to do a quick temperature check.

I use an original style neck and drill and tap a hole at the rear. If done properly, there is no interference with anything else. Why the heck did they not do it that way - maybe the designer had never seen a Model A engine. |

Y-B - that is a gorgeous engine compartment! Acorn nuts on the head, no less. I'm jealous. JayJay |

Re: Temperature Gauge Installation Jim, something you might want to be careful about when running the line through the terminal box and if it is metal. Keep in mind the two screws that hold the cover on are also what the wires hook to and are hot. I didn't like how the previous owner had ran the sender wire and changed it only paying attention to the looks. The first time I fired it up the gauge no longer worked and I couldn't figure out why so after driving it a couple months I decided to take the sender bulb loose to see if there was an issue there. While taking the bulb loose I noticed smoke coming out of the terminal box and with an ole F*** I quickly disconnected the battery. I removed the cover and discovered the sender metal wire had shorted across the two screw post and burnt the wire into and that is why the gauge no longer worked. Luckily the wire had initially burnt out quickly and didn't cause any other damage but when I started moving it around taking the bulb out it touched again causing the smoke to escape out of the wires. There is now a piece of rubber covering that area; you don't want to be making smoke in the terminal box.
