There is a simple way to guesstimate the temperature by looking at the mercury rising in the car. Get a near thermometer, or some other cheap thermometer with the range of 0-4-- degrees and pull over while driving normally and measure the temperature of the radiator water. Note where the mercury is. Then do it when it is a hot day and the mercury is quite a bit higher. You will have some base points. Use caution and a rag, don't get scalded. If the car is steaming, wait a spell. Most motometers have some type of scale on one face, turn that one to be visible from the drivers seat.
