Warm up the engine. The minimum oil temperature must be +80°C. The specified temperature under normal conditions is reached after 15 km of driving.
Engine displacement 1.6l (4A-F, 4A-FE, 4A-GE, 4A-GEL): Remove alternator, insulate the connecting cable well and lay it aside so that it does not get into moving parts.
Disconnect the cable from the pressure sensor and remove it. The figure shows a variant of the petrol engine. For a diesel engine, the pressure indicator is located on the oil filter flange.
Screw in a pressure gauge instead of the pressure indicator.
Start the engine and at the control speed measure the oil pressure.
Oil pressure
Engine model | Idling | 3000 rpm |
Gas engine | min 0.3 bar | 2.5-5.0 bar |
Diesel | min 0.3 bar | 2.5-6.0 bar |
Lubricate 2-3 turns of the connecting thread of the pressure switch with sealant, for example, Loctite 242 and screw it into place.
1.6L engine (4A-F, 4A-FE, 4A-GE, 4A-GEL): Install the generator and connect the cable.
If the oil pressure differs from the specified value, see section "Lubrication system malfunctions".
