Correct oil/water gauge for Us S3
5 posts
• Page 1 of 1
Picked up a bit of a project and it was unfortunately the "parts car" for the previous owner. With that, several parts are completely missing, one of them being the dual gauge. I have seen several different options and would like to get the correct one. 100psi/230F smiths 2". 60psi/110C smiths 2" with illumination hole for bulb in back. Several gauges I have are illuminated with a bulb in the side. Is there another option with 60psi/230F that I haven't seen yet? Any suggestions would be appreciated looking to buy the right one the first time.
Car is 67 Elan coupe airflow pre super safety. I think it is an SE.

As far as I know (other do more) there are two pressure combinations
60 and 100 psi, the later is needed if you have a high pressure oil pump,
but I don't think that this was a standard factory option.... maybe on race cars ?!
So standard pressure is 60 for sure.
230F or 110C is a question of the units you use in your country, in Europe UK has Fahrenheit,
the continent had Celsius. I would (intuitively) say that the US had Fahrenheit.
Just my thoughts...

The one in my Elan was a Smiths model GD1500/74
0-100 PSIG
30 to 100c temp
Lighted from the side.
The "74" denoted the length of the capillary tube.

There is no cure for Lotus, only treatment.

Johan,
I don't know what is correct, but my car (1968 S4) as I bought it had Farenheight and psi. A friend with more knowledge said it should be Celsius and psi. I exchanged my gauge for Celsius.
At about the time my car was built Britain was moving to the Celsius scale, so I assume the earlier cars were Farenheight and the later Celsius.
