Engine Coolant Temperature: Tachometer

WARNING: This page is about a different car, the 2011 RAM Pickup and 2011 RAM Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

A tachometer is standard equipment on all instrument clusters. The tachometer is located to the left of the speedometer, just to the left of center in the instrument cluster. The tachometer consists of a movable gauge needle or pointer controlled by the instrument cluster circuitry and a fixed 210 degree scale on the gauge dial face. The tachometer reads left-to-right from 0 to 7 . The text RPM X 1000 is imprinted on the cluster overlay directly below the hub of the tachometer needle. This text identifies that each number on the tachometer scale is to be multiplied by 1000 RPM.

The tachometer graphics are white against a black field making them clearly visible within the instrument cluster in daylight. When illuminated from behind by the panel lamps dimmer controlled cluster general illumination lighting, the scale graphics appear white and the red graphics still appear red. The gauge needle has internal optical illumination. Gauge illumination is provided by a Light Emitting Diode (LED) unit located on the instrument cluster electronic circuit board.
