Found a rebuilt temp guage for my '34 Standard, since the original owner wouldn't spring for that accessory I don't have one and don't know where it's supposed to go on the dash. Couldn't find any indication of location from the back of the dash, any help is appreciated. As is there's the speedo, amp, and fuel /oil pressure combo guage.

The temp. gauge was not offered for the 1933-34 Standard from what I can find.Infact a temp. gauge for a 1935 Standard isn't shown in the literature that I have.May have been introduced during the 1935 year or first available when the 1936 Standard came out.The later catalog (1939) shows the same gauge for 1935-36 Std.In 1936 the gauge was located on the extreem left side of the dash.The '35's that I have seen with a gauge have it to the left of the inst. cluster.I am sure that some one with a 1935 will feed in the facts.
What color is the face of the gauge you have?The '34 Std. had a black face with white numbers and needle.The 1935 has a dial with a dark brown center and cream outter area.The 1936 has cream outter and black center with red needle.

I haven't forgotten about the wire harness-will get back to you in a day or two.

PS- Also check to see if the gauge will fit into the proper hole in the cyl. head.Its in the left rear corner on top of the head next to the left rear corner of the valve cover.The heater hose connector also threads in there.There was a pipe plug there from the factory.The parts book shows a special fitting was used in that location the the temp. sender threaded into.The specail fitting is shown for all models from 1930-1940 EXCEPT CC and DC and I am thinking it will not fit into a 1934 DC head.The book shows a %/8"-18 internal thread X 1/2 taper ext....its kind of a specail adaptor for the sender fitting.
The head may not be designed for a temp. guage on the Std.

Seems like I'm always thanking you Gene, but you are the source of all sources. The manuals you've posted are invaluable also. Wish you lived closer so I could have you as my mechanic. If you ever come to Florida (don't know why you'd want to) I have plenty of room at my house for visitors.

Chevrolet Parts and Accessories Merchandising Bulletin Nov. 13, 1935 shows the temp. gauge installation in a 1936 Standard. It shows the cylinder head fitting installed as p/n 358147, installing dash grommet p/n 117971 in a 3/4 in. dia hole just to right of speedometer level with the ignition switch. Wiring for gauge lamp is spliced into lamp harness next to ampmeter. Temp gauge is to left of instrument cluster in a 2 in. hole centered side to side and 3 & 21/32 up from bottom of dash panel. I have not found any Bullentins for 34 or 35 Standards but would think they were similar.

Send me your email adress and I will send you the installation instructions for 34-35 Standard accessory temp guage

But the 358147 is listed in 1n the 1934 parts book as not used in 1933-34 Standard???????The 1935 Std. used the 1934 Master cylinder head so the fitting for the temp. gauge would have fit that model.The pictures that I have of the 1933-34 Std heads does show a square pipe plug in the corner but I am wondering if it had a different thread configuration than the other models (ie '35 Master etc.)
The 1934 and 1935 Standard instrument panels have the same layout.Only the colors/trim was changed.

The Bullentin says to remove the cylinder pipe plug p/n 103868 and to install p/n 358147. My 35 parts book, dated Dec, 1935, indicates nut, water temperature gauge in cylinder head, is used on all 1930 -1936 except CC & DC. There is no water temperature gauge for the CC or DC models listed in this or earlier parts books.

Thats the problem- he has a DC.....will the fitting thread into a DC head.I think I have a new fitting.I will have to look at it and see what threads it has.The CC-DC head was not designed for a temp. gauge as it wasn't offered for those years.

None of the 1934, 1935 or 1936 parts books have a plug listed for the rear of the 34 DC cylinder head; then a good guess would be the plug at LR corner would be a standard pipe plug fitting since Chevrolet didn't normally assign a part number to standard size common fasteners & fittings.

In looking at the left side engine pictures from the proving grounds the 1934 Standard has the same plug as the 1935 and 1936 Standard.Actually this location was used from to reasons on the 1934 and prior engines.The temp. gauge was located there on the models so equipped and the heater hose also connected their if a Genuine chevrolet heater was installed.
I have a new heat indicator fitting (part#358147-later changed to 597630)...It has 3/4" pipe thread to thread into the head and 1/2 thread (internal( with a tapered seat to seal the gauge. Looks like ther would be no reason that it would not fit any 1930-1940 head.

The Accessory temp gauge location for a 35 Standard is directly above the steering column and centered vertically with the two large round lenses in the instrument cluster. 35 and 36 gauges are the same except for the color difference. Once the 36 gauge was available and the stock of 35 color gauges was exhausted, the 36 color was offered as the gauge for both models. Gauges packaged for 36 use included a trim ring which was slightly wedge shaped to square the instrument up with the driver for better viewing.
