This coolant temperature gauge is a round gauge which is inserted into the gauge panel via a 2 1/16 diameter hole. It is clamped into place from behind the panel face with the supplied plastic back clamp, nuts and washers. The gauge face is black with white markings and a white pointer. The pointer travels from left to right over approximately 60 degrees of arc with a range of 100 degrees on the left and 250 degrees on the right. The gauge has dual dial markings, degrees Fahrenheit primary and degrees celsius secondary. This gauge is designed to be used on engines with a 12 volt dc battery system. We can supply an optional resistor card (see resistor card) for use on 24 volt DC systems. The trim ring around the face of the gauge (the bezel) is black. The gauge can be illuminated via a bulb inserted from the rear of the plastic case. This feature is supplied as part of our standard offering but does not have to be used by the customer. This gauge requires a pressure sender with 460 ohms @ 100 degrees to 29 ohm @ 250 degrees.
