Do the US-spec temp gauges correspond to a US-spec temp sending unit, likewise a German gauge to a German sending unit? What happens if you use a German gauge with a US sending unit, are the readings accurate, high, or low?

Thanks

I don't know if your question has been answered. 0 to 150c sender matches the 50 to 150c gauge and the up to 300f gauge, the 0 to 170 matches the up to 340f. gauge. The 0-200 matches the up to 392f or 400f gauge. Most of the vdo senders have the range stamped on them. I hope this helps Mark

There is no "US-spec sending unit", nor a "US-spec gauge". The gauge was not numbered (except for the calibration marks waaaaay out on the edge where you can't really see them with the gauge module installed; those were in degrees C in all cases) so there wasn't a need to run different gauges for the places that used different units and measuring systems.

So the oil temperature/pressure gauge that has bar and Celsius numbers are identical to the ones that have Fahrenheit numbers for the oil temp? That’s all I really need to know. I am working on a car that has a massive front oil cooler and a very mild motor and it insists on running at 120 deg c, I just wanted to know if there could possibly be a mis-match with the gauge and sender. I will reference the part numbers off of the chart above when I am able to get to the car tonight.

Thanks,

The original Six gauge was not numbered.

I am told that the 911 gauges (some of which are numbered) use identical "guts" between the F and C versions, just the face is different.

now here is another fine question....

i have a STOCK 4 cyl gauge insert (non numbered temp) and would like to know the affect of running a numbered 911 gauge module (readouts the same?)

also for oil pressure-
VDO dual sender is that the same VDO dual sender used on 911s? (would like to run a 911 pressure gauge off my VDO dual sender)

Thanks,
Aaron

The 911 temp gauge would read incorrectly if you used the 914-4 sender. I don't remember if it would read too high or too low, but it would be off.

The dual pressure senders (i.e., both light and gauge) on the 914 are all aftermarket. I have heard from one source that the resistance range used on the aftermarket senders is the same or "close" to that used by the 911 gauges. I don't know this for a fact, though. If so, you could just plug in a 911 pressure gauge to the aftermarket 914 dual pressure sender.

This is pretty old info, but they are different.
