Doug, do you have a thermometers? Wife's meat thermometers would work if it goes to 200 plus. Press it against the hose or touch the water outlet.
I use a infrared digital laser pyrometer. Great tool to have when working on a Cobra. No guessing about the temp of the
oil, water, block, radiator, headers, etc.
The gauge read low on my
oil temp till I moved the sensor to the remotor
oil filter.
