The oil drain port is located on the bottom oil pan of the transmission, while the oil filler port (inspection port) is on the left side at the rear of the transmission. The oil drain port functions as an automotive oil drain valve that utilizes vacuum suction to discharge waste engine oil. Similar to a toilet flush, it creates a vortex in the oil pan to lift and remove sludge and other sediments, preventing contamination of new oil. This enhances engine performance and extends engine lifespan. Engine maintenance items include: 1. Regular oil and oil filter replacement; 2. Maintaining proper crankcase ventilation; 3. Periodic crankcase cleaning; 4. Regular fuel system cleaning; 5. Routine radiator maintenance; 6. Fuel system maintenance and cleaning.

How to Start as a Used Car Broker for Beginners?

You need to be able to identify whether it's an accident-involved vehicle, as such cars are tricky in the current market—handling them poorly could lead to losses. At the very least, you should be able to inspect the car's condition by looking, smelling, and listening. Sellers will naturally first inquire about the price of their car from the broker. At this point, the broker should absolutely avoid rushing to lower the price.

How to Drive on a Highway with Only 2 Lanes?

Before entering the highway, the car owner must go to a repair shop or 4S store to check whether the vehicle's condition is normal and whether the tire pressure is normal. The speed should not be too fast, but also not too slow, because there are maximum and minimum speed limits on the highway, and you cannot change lanes back and forth. You cannot always drive on the left side, because the left lane is for overtaking and cannot be used continuously; it should only be used when overtaking.

Where is the Altima air-fuel ratio sensor 1b1 located?

The Altima air-fuel ratio sensor 1b1 is located above the three-way catalytic converter, with the V6 engine B1 air-fuel ratio sensor positioned on the left side. Since the three-way catalyst's purification capacity for CO, HC, and NOx drops sharply once the air-fuel ratio of the mixture deviates from the theoretical value, an oxygen sensor is installed in the exhaust pipe to detect the oxygen concentration in the exhaust. It then sends feedback signals to the ECU, which in turn adjusts the fuel injection volume from the injectors, thereby maintaining the air-fuel ratio of the mixture near the theoretical value.
