Coolant circulation pump output has electrical faults or open circuits, coolant circulation pump output terminal is short-circuited to ground, coolant thermostat has electrical faults or open circuits. Reasons for water not circulating: Coolant circulation pump output has electrical faults or open circuits, coolant circulation pump output terminal is short-circuited to ground, coolant thermostat has electrical faults or open circuits. Water circulation bleeding method: First, fill the coolant to the maximum level, then open the radiator cap. Insert the key, turn on the ignition switch to power on (but do not start the engine). Then, set the air conditioning to heating mode and adjust to the highest temperature, with the air volume at the minimum setting. Press the accelerator pedal all the way down for about 10 seconds, and you will hear the sound of the electric water pump working. After the pump runs for a while, the air inside the engine will be expelled.

What does 'Four Days On, Four Days Off' in Guangzhou mean?

Guangzhou's 'Four Days On, Four Days Off' policy refers to the regulation that non-Guangzhou registered small and medium-sized passenger vehicles, including those with temporary license plates, entering the restricted areas of Guangzhou, are not allowed to drive continuously for more than four days. If they wish to enter again, they must wait for at least four days. In other words, vehicles with out-of-town license plates can drive for a maximum of four consecutive days, and after driving for one day, they must wait for four days before they can drive again. The purpose of implementing this policy is to focus on reducing the high traffic intensity caused by non-local vehicles in the central urban areas of Guangzhou, thereby minimizing the impact of these vehicles on local traffic. The controlled areas should form a network to prevent regulated vehicles from entering the controlled zones through alternative routes, which could undermine the effectiveness of the control measures.

How to Read the Oil Dipstick?

Reading the oil dipstick involves the following steps: 1. Unscrew the dipstick and wipe it clean with a clean soft cloth or tissue; 2. Reinsert the dipstick and then pull it out again. There are upper and lower limits marked at the end of the dipstick. Observe the part of the dipstick that is wetted by the engine oil; 3. If the oil level is between the upper and lower limits, it means the oil quantity is just right. If the dipstick does not reach the lower limit, it indicates insufficient oil. If the oil level is above the upper limit, it means too much oil has been added. The oil dipstick in a car is a commonly used measuring tool to check the lubricant level in the oil reservoir. Due to the curved path of the dipstick insertion hole, the dipstick must be able to deform when inserted and rebound to its original shape when pulled out.

When should a new car undergo its first maintenance?

New cars should undergo their first maintenance after driving 3,000 to 5,000 kilometers or 3 to 5 months. The first maintenance for a new car includes the following items: 1. Check the engine's working condition, such as whether the pipe connections are normal, whether there are any leakage points, whether the engine sound is normal, and whether there are any abnormal noises; 2. Check whether the coolant level is within the normal range; 3. Check the wear degree of brake pads and tires, as well as the tire pressure condition; 4. Check whether there are any scratches or corrosion on the chassis components; 5. Check the remaining amount of power steering fluid and whether there is any oil leakage at the oil pipe interfaces; 6. Thoroughly clean the vehicle, including the engine compartment, body, and interior.

What is the coolant bleeding method for the Baojun 560?

The coolant bleeding method for the Baojun 560 involves first ensuring that the old coolant is mostly drained out. Then, slowly fill the radiator to the top, followed by filling the overflow tank to the top without replacing the radiator cap. At this point, start the engine and let it idle until it reaches normal operating temperature. As the coolant begins to circulate through the system, the engine will automatically expel any air trapped in the coolant passages. Coolant is a liquid containing special additives, primarily used in liquid-cooled engine cooling systems. The Baojun 560 measures 4670mm in length, 1810mm in width, and 1755mm in height, with a wheelbase of 2750mm. The front track is 1554mm, and the rear track is 1549mm. The vehicle's engine delivers a maximum horsepower of 150Ps, a maximum power output of 110kW, and a maximum torque of 230Nm.
