Automotive coolant, also known as antifreeze coolant, is a medium that ensures the proper functioning of water-cooled engines. The main components of coolant are: water, antifreeze, and additives. Depending on its composition, it can be classified into: alcohol-based, glycerol-based, and ethylene glycol-based. The functions of automotive coolant are: 1. Prevent engine block from cracking: Prevents the coolant from freezing and causing the radiator and engine block to crack after parking in winter. 2. Prevent corrosion: Protects the radiator, water pump, engine block and cylinder head, and water distribution pipes from corrosion. 3. Reduce scale formation: Minimizes scale buildup to avoid clogging the circulation pipes and affecting the cooling system's heat dissipation function. 4. Meet cooling demands: Satisfies the heat dissipation and cooling requirements of high-load engines.

What is the tire pressure for a BMW 5 Series?

The standard tire pressure for a BMW 5 Series ranges between 2.2bar and 2.5bar. If the tire pressure is too low, the braking distance will correspondingly shorten, and the car will consume more fuel. Additionally, driving with low tire pressure can cause the fragile tire sidewalls to continuously compress and rebound, leading to tire fatigue, accelerated temperature rise, and potentially causing a tire blowout at certain temperatures. The BMW 5 Series has a body length, width, and height of 5047mm, 1860mm, and 1491mm respectively, with a wheelbase of 2888mm. In terms of appearance, its overall design features iconic BMW elements, presenting a sleek, elegant, and dynamic profile with smooth lines. The powertrain of the BMW 5 Series has been further enhanced, with the high-end 545i model equipped with a V8 engine from the 7 Series, delivering a maximum power of 245 kW and a maximum torque of 450 Nm.

How often should the spark plugs be replaced on a BMW X1?

The spark plugs on a BMW X1 should be replaced approximately every 30,000 kilometers. The BMW X1 has four spark plugs, arranged in a row within the engine. After about 30,000 kilometers of use, the performance of the spark plugs begins to decline. Once performance deteriorates, the ignition efficiency of the spark plugs decreases. If not replaced in time, the ignition efficiency will drop by 5% to 10% for every 10,000 kilometers driven. When the performance of the spark plugs declines, the vehicle's fuel consumption will increase, and carbon deposits may form in the engine. If the engine feels underpowered, it could indicate an issue with the spark plugs. The BMW X1 features a MacPherson independent front suspension and a multi-link independent rear suspension. The vehicle's dimensions are 4565mm in length, 1821mm in width, and 1620mm in height, with a wheelbase of 2780mm.
