Safety valve (ref. 15 54 056 0N)
The two safety valves are located in the oil pan, starboard
side, and can be accessed by the cylinder 6 inspection trap.
These valves, loaded to a pressure of 7.25 bars, are
designed to limit oil pressure in the engine circuit, when
starting the engine and the oil is still cold.
Never exceed an engine speed of 1,000rpm until water
temperature reaches 60 °C.
