- Checking the oil pressure should be carried out on a warm engine (~80°С).
- Connect a pressure gauge instead of the oil pressure sensor (To remove the sensor, use a 22 mm high socket).
- Start the engine and measure the oil pressure at various engine speeds.
Oil pressure values:
- at 1000 min-1: minimum 1.2 bar
- at 3000 min-1: minimum 3.5 bar
- Turn off the engine and remove the pressure gauge.
- Install the oil pressure sensor with a new seal.
- Check the engine oil level.
The cooling system of a closed smart unit includes a water pump, a cross-flow radiator, a radiator fan with an electric wire, a thermostat, a heater core, hoses and temperature sensors. The radiator fan with an electric wire is turned on when the contact temperature sensor is activated. On automatic transmission models, some of the fluid circulates through the transmission fluid cooler
