The oil pressure switch is located in a port at the front LH side of the cylinder block. It detects when a safe operating
pressure has been reached during engine starting and initiates the illumination of a warning light in the instrument cluster
if the oil pressure drops below a given value. The switch operates at a pressure of 0.15 to 0.41 bar (2.2 to 5.9 psi).
Engine Block Heater
For cold climate markets an engine block heater is fitted, which is located at the front of the LH side of the cylinder block.
