3. Screw the oil pressure tester into the thread hole of oil
pressure switch as shown in the illustration.
4. Start engine. When the engine inspection conditions are met, read the oil pressure values at low idling
speed, high idling speed and high speed respectively. If lubrication system pressure is low, clean the oil
pan and oil strainer mesh, and then test again. If lubrication system pressure is still low, it shows there is a
malfunction in the oil pump and the oil pump must be replaced.
Oil pressure at idling speed (700 ± 50 r/min): higher than 1.5 bar.
Oil pressure at high idling speed (2000 r/min): higher than 3.6 bar.
Oil pressure at high speed (4000 r/min): higher than 4.7 bar.
