BMW x5n55 engine cooling system: turn off the coolant pump due to locking?

1. In this case, the thermoster generally fails, either stuck in the normal open position, or it cannot be opened and cannot carry out a large cycle, resulting in the water pump being forcibly locked [car problem, ask the car master. 4S store professional technician, 10 minutes to solve.

2. Yes, the coolant pump is stuck, resulting in excessive current. The computer enables the protection mechanism to cut off the power supply.

3. The coolant pump of the BMW engine cooling system is turned off due to locking. There is no large cycle due to the failure of the thermosther is not turned on. At this time, the system will lock the water pump to prevent the cooling system pipeline from bursting due to high pressure. Replacing the thermoster can solve the fault.

4. The BMW X5 coolant pump is closed due to blockage. There are the following solutions: remove the engine intake system: the contemporary automobile intake system is mainly a variable intake system. Variable air intake systems are mainly divided into four types: VVT, CVVT, VVT-i and i-VTEC. Replace the engine thermoster: The car thermoster is a valve that controls the flow path of engine coolant.

What is the common disease of BMW n55 engine? TreasureMa n55 electronic valve common disease

n55 engine has poor heat dissipation, valve chamber cover pad oil seepage, valve oil seal failure, etc. The n55 engine is a product launched by BMW to replace the previous n54 engine. N54 has dual turbocharging technology, and n55 is a single-turbine double-vortex tube supercharging technology. The n55 engine is equipped with BMW's proud double vanos and valvetronic electronic valve technology.

n55 engine common disease N55 engine heat dissipation is not good, valve cover gasket oil leakage, valve oil seal failure, etc. The n55 engine is a product launched by BMW to replace the previous n54 engine. N54 has twin-turbocharging technology, and n55 has single-turbine double-swirl tube turbocharging technology.

N55 engine heat dissipation is not good, the valve chamber cover gasket leaks oil, the valve oil seal fails, etc.The n55 engine is a product launched by BMW to replace the previous n54 engine. N54 adopts twin-turbocharging technology, and n55 adopts single-turbine double-vortex tube turbocharging technology.

According to the internal technical notice of BMW, the common faults of the n55 engine include: occasional shutdown and no fault code; abnormal noise or power drop; and the engine cannot be started again after programming.

17 Middle East version 3.0T BMW x5 engine model is N55?

1. BMW X5 and 2017 differences: different engines, different maximum power/maximum torque, different fuel consumption under mixed working conditions [L/100km] Different engines 2018 models: 0T inline 6-cylinder turbocharged engine.

2. The engine used by BMW x5 is the N55 engine. N55 technology is an engine developed by BMW Group with direct injection device Valvetronic and exhaust gas turbocharging. Although it has ranked first among the top ten engines of Ward, a well-known ranking agency, for several consecutive years, it is the mainstay of the power system that matches BMW's medium and high-end models.

4. In terms of the engine, both have 0T power. The engine model is B58B30C engine for X5 and B55B30A engine for X6. Whether it is maximum power or torque performance, the X5 is obviously stronger. ( In terms of emissions, X5 is Euro 6 emissions, and X6 is medium 6 emissions). China's emissions are stricter than Euro 6, which is also the reason why the power of the X6 engine is smaller than that of the X5.

5. Low-displacement N55 single supercharged 0L, maximum power 306 horsepower, peak torque 400 Newtons/m. The acceleration time from 0-100km/h is about 5 seconds, the maximum power of the 8L engine is 360 horsepower, the peak torque is 500 Newtons/m, and the acceleration from 0-100km is 2 seconds.
