Your car’s fuel gauge works to approximate your gas level in the tank. Cars nowadays are almost all equipped with a warning light that automatically turns on when the gas level becomes too low. Since the fuel pump is submerged in gasoline as a way of cooling off, when the gas reaches a too low level, the pump is exposed to air, overheats, and probably in turn suffers pump failure. And for that reason, you need to check the fuel gauge regularly.

The dashboard shows alarming levels of the temperature of the engine coolant. However, different cars may have different ways to display that message. Most of the time, there is a gauge that uses C and H to indicate cold and hot but while some cars have a thermometer that activates red lights on the dashboard to inform you the engine coolant is gaining excessive heat.

Tachometers help the driver to know the speed he/she is at by consulting RPM figures (Revolutions per minute). In case the gauge hits perilously high levels which are indicated by red on the tachometer, it means the engine is rotating at a high velocity. You shouldn’t neglect the tachometer reading since it’s is closely related to both fuel economy and power output. To put it easy, the higher the RPM is, the more fuel consumed, and the more power is generated. It is ideal when the rpm reading is low and consistent which means a good fuel economy and an engine operating at its optimal levels.

Oil Pressure Gauge/Lamp
While older models have oil pressure gauge, newer models feature a warning lamp, which both can caution the drivers when the oil levels come low. Oil pressure is essential to the performance of the engine, without which it can suffer serious failure. If the gauge reads low or the oil lamp beams, make sure to bring your vehicle to the nearest car service.
