has second radiator behind the main radiator known as heat exchanger. The oil going towards engine block
passes through it and cool the oil when comes in contact with air of fan.
The second system is cool the oil by water as we known the temperature of water less than oil. Oil rotates around
the water tube and becomes cool.
Oil level indicator
An instrument that displays the oil level in the oil sump is known as an oil level indicator. Either a dipstick, shows
the minimum and maximum oil levels. A dashboard gauge or light receives a signal from an electric sensor.
Oil pressure gauge
An instrument that gauges the pressure of the oil in the lubricating system is known as an oil pressure gauge. It
can be mechanical or electrical in nature. A fluid filled tube drives a moving needle on a dial in mechanical gauge.
Using a sensor, an electrical gauge transform pressure into a signal that moves the needle or display a digital
readout.
