Is the 200 degree mark the 11 0'clock or the 12 0'clock slash on the gauge :huh: Thanks guys.
A picture of the gauge would help::




Look at the numbers on the gauge, if full scale is 250, and there are 6 marks on the gauge, then each mark is = to 41.6*

:cheers:

The accuracy of the temperature gauge is always in question as well. An I.R. temperature gun should be used to confirm gauge function.

If you remove the sender wire at the engine and put a 68 ohm resistor between that wire and ground your dash gauge should read about 215*.

I thought they all were clearly marked, mine not marked but is 180 to the left, marked at 210 for straight up, and 250 over to the right extreme....

I thought late sharks had similar markings....??

:cheers: at any rate, with the stock sender, my gauge was allways right on, proven with my immersion probe many times over, when I changed heads to later aluminum L98 heads #113, i had to recal the gauge on account of I forgot to get the head drilled for the OEM old sender....
