Oil Gauge

• The oil gauge in a Jeep is usually located on the instrument cluster and is used to monitor the oil pressure in the engine.
• It is usually a round gauge with a needle that moves up and down as the oil pressure changes.
• The gauge monitors the oil pressure in one of the main oil ways near to the pump and filter. 
• To do this it has a tapping in the engine block, into which is screwed a sensor (for electric gauges) or an oil pipe take-off (for mechanical gauges)
