At what temperature does the Corolla's cooling fan activate?

Corolla's cooling fan starts operating when the coolant temperature reaches 98°C. The radiator fan is automatically controlled and cannot be manually operated. It remains off at low temperatures and operates at two different speed levels for medium and high temperatures. Radiator fan overview: The activation or deactivation of the radiator fan (cooling fan) is controlled by a thermal switch located on the radiator. When the coolant inside the radiator reaches a specific temperature, the thermal switch triggers the fan to start. At higher coolant temperatures, the thermal switch increases the fan's rotation speed. Factors determining fan operation: The operation of the vehicle's cooling fan depends solely on coolant temperature, not time. Only after the engine has been running for some time and the temperature rises does the coolant temperature in the radiator increase. When the coolant reaches 95°C, the fan activates and operates at approximately 1,600 RPM. At 105°C, the fan speed increases to about 2,400 RPM to enhance cooling efficiency.

What is the problem when the car won't start?

The reasons why the car won't start include damage to the water pump, air conditioning compressor, clutch, generator, power steering pump, and the bearing of the belt tensioner pulley. Specific reasons why the car won't start: Faulty spark plugs or ignition coils; engine motor idling; slipping of the flywheel ring gear; insufficient battery power; poor quality gasoline. Solutions for when the car won't start: Check the battery's power status and charge it in time; check the gear position to ensure it is in the correct gear; inspect the condition of the spark plugs and ignition coils, and replace them if necessary; add gasoline with quality assurance; check the working condition of the engine and transmission.

How many liters of engine oil does the Volkswagen Touran require?

Volkswagen Touran requires 4.5 liters of engine oil. Diesel engine oil: There are two main factors in selecting the quality grade of diesel engine lubricating oil. First, based on the combined mechanical and thermal load of the automobile engine, expressed by the intensification coefficient; second, according to the severity of the engine operating conditions. Gasoline engine oil: The severity of engine operating conditions and the additional devices in the intake and exhaust systems of imported vehicles, as well as the production year, are used to select the appropriate performance grade (quality grade) of gasoline engine oil. Generally speaking, a higher quality grade can replace a lower quality grade oil, but never use a lower quality grade oil to replace a higher quality grade oil, as this may lead to engine failure or even damage.

What is the fuel consumption of the new Transit diesel?

New Transit fuel consumption per 100 kilometers: 8.7L/100km. How to calculate car fuel consumption: Fill up the car's fuel tank completely and reset the odometer to zero. After driving for a period of time, refill the tank and note how many liters of fuel were added. Then, divide the amount of fuel added by the distance traveled to get the fuel consumption per kilometer. Reasons for high fuel consumption: Driver's skill level, improper gear shifting and excessive braking during driving, which artificially increase engine power loss. Frequent braking also leads to more starts, as fuel consumption rate is very high during acceleration. Driving at low temperatures - the engine is designed to operate at normal temperatures. If the car is driven without proper warm-up, the engine remains cold, resulting in poor fuel atomization and incomplete combustion.

Why is the sunroof of GAC Trumpchi leaking?

Mostly, the sunroof leakage in cars is caused by blocked drainage pipes, while door leakage is generally due to aging window seals or clogged door drainage holes. Door leakage can result in water seeping out from the door panels and, in severe cases, lead to water accumulation under the cabin carpet. Poor rainwater drainage: Blocked sunroof drainage outlets can cause poor rainwater flow, gradually seeping into the car. This phenomenon mainly occurs when the owner neglects regular cleaning of the roof, allowing debris to flow with rainwater and clog the drainage outlets. Damaged sunroof seal: The sunroof seal is made of rubber and can age over time. Repeated friction from the sunroof glass can cause damage, leading to poor sealing and leakage during rain. In such cases, it's essential to regularly check the condition of the seal and replace it promptly if damaged. Roof deformation: If the car suffers an impact, the body may deform. Improper restoration during repairs can result in poor sealing and subsequent leakage.

What are the sizes of motorcycle helmets?

Motorcycle helmet size chart is as follows: XS (53-54) S (55-56) M (57-58) L (59-60) XL (61). Introduction to helmets: Helmets are head protection equipment, worn by military personnel during training and combat, and are indispensable tools in transportation. Mostly semicircular in shape, they mainly consist of three parts: shell, lining, and suspension system. The shells are made of materials such as special steel, fiberglass, reinforced plastic, leather, and nylon to protect against bullets, shrapnel, and other impacts to the head. In ancient China, they were called zhou, shoukai, doumou, or toumou. Composition of helmets: Modern helmets mainly consist of the shell, lining, and suspension system. Due to different requirements for various activities, there are many structures and styles of helmets.
