Here is some research I did a while back on the subject.
We were wondering at what temp the fan came on for the oil cooler on a Foreman 450. We saw all the tests in the manual but did our own. All Measurements in deg F.
We used a Snap on Multi meter with a digital temp probe. The ambient air temp was 71 degrees. The oil temp on a cold engine was 71 Deg.
The Oil temp switch measured 98.4 K Ohms.
The engine started and run until the fan came on (about 15 min at a fast Idle) then shut down and immediatly the oil temp and resistance on the switch was measured.
Oil temp was 210 deg, and the resistance at the switch was 1.01 K Ohms.
Hope this is of some use to you.
