Mercedes-Benz E200 has 2 coolant temperature sensors. Introduction to coolant temperature sensor: The coolant level and temperature sensor consists of a thermostat section and a water level control section, with matching components including a pressure reducing device before the electric valve and a rotary muffler heater for heating. Function of coolant temperature sensor: The temperature sensor converts coolant temperature into electrical signals to adjust fuel injection quantity (increasing injection during cold starts), modify ignition timing (advancing timing at low temperatures while delaying it at high temperatures to prevent knocking), and influence idle control valve operation (ECU controls idle speed based on sensor signals during cold starts to increase RPM).

What is the normal tire pressure for the Touran?

The normal tire pressure for the Touran is between 2.3 and 2.5 bar. Factors affecting tire pressure include: 1. Seasonal factors—tire pressure varies in summer and winter due to thermal expansion and contraction; 2. Load conditions—tire pressure differs when empty, half-loaded, or fully loaded; 3. Tire condition—tire pressure varies between severely worn and unworn tires. Taking the 2021 Touran as an example, its body structure is a 5-door, 7-seat MPV, with dimensions of 4527mm in length, 1829mm in width, and 1659mm in height, a wheelbase of 2791mm, a fuel tank capacity of 60 liters, a luggage compartment capacity ranging from 137 to 1857 liters, and a curb weight of 1515kg.

(3) Brake fluid. (4) Coolant. (5) Spark plugs. 2. Precautions for major maintenance: (1) Tires: Regularly check tire wear and air pressure. Replace tires promptly if the tread is severely worn. (2) Seat care: Without protective measures, genuine leather seats will wear over time. Consider purchasing seat covers that match your vehicle model. (3) Windshield protection: Applying a protective film can prevent unnecessary scratches.

Where to Turn on the Position Lights?

The control switch for the position lights is the light knob. For models with only manual light functions, turning the light knob one notch will turn on the position lights, and another notch will turn on the headlights. For models with automatic headlights, turning the switch to the AUTO position will automatically illuminate the position lights when the ambient light is dim. Below is relevant information about position lights: 1. Function of Position Lights: Position lights are warning lights used primarily in low-visibility conditions to alert other vehicles. 2. Position Lights Can Also Be Turned on in Hazy Weather: When the headlights are on, the position lights will also be on. In hazy weather, during evening driving, or in light rain, the position lights can be turned on separately without needing to turn on the low beams (since low beams are ineffective during the day), making it easier for vehicles ahead and behind to identify your car.

Is it legal to modify a car with wide body kits?

Modifying a car with wide body kits is illegal. Below is relevant information about car modifications: 1. Purpose: To enhance performance, the modification of the powertrain system is the most critical aspect of car modifications. To improve a car's power, it is necessary to replace components such as spark plugs (ignition plugs), high-voltage wires (ignition leads), air filters, fuel-saving accelerators, water-fuel devices, horsepower boosters, electronic rectifiers, and exhaust pipes. 2. Modification Methods: Enhancing car performance by modifying the engine involves boosting engine power, reducing fuel consumption, lowering exhaust emissions, and extending the engine's lifespan. The primary goal is to ensure that the combustible gases entering the engine are fully and completely mixed, allowing the powerful spark plugs to ignite the mixture for complete combustion. This is achieved by replacing and upgrading components and installing auxiliary products to improve engine performance from three aspects: the air intake system, electrical system, and fuel system. The biggest advantage of this method is the convenience of installing and removing modification parts, allowing the engine to be restored to its original state when not in use.
