Ford Focus's fan continues to run after engine shutdown to cool down the engine. Here are specific details about automotive cooling fans: 1. Automatic activation conditions: The radiator fan automatically turns on when coolant temperature reaches 98°C. The car's radiator fan activates automatically and cannot be manually controlled. It remains off at low temperatures and operates at two different speed levels for medium and high temperatures. 2. Medium and high fan speeds: Typically, the fan automatically activates medium speed at 95°C and high speed at 105°C. When coolant temperature reaches 95°C, the fan starts running at 1600 RPM. When temperature reaches 105°C, the fan speed increases to approximately 2400 RPM to enhance cooling efficiency.

How to Handle a Rear-Wheel Drive Car in Snowy Weather?

Driving slowly can effectively prevent skidding and side-slipping. Maintain sufficient distance between vehicles. Driving on snow-covered roads with reduced friction can minimize sudden braking. If the car starts to skid, you can turn off the active safety assistance system by pressing the DTC button on the center console for 3 seconds to deactivate the DSC function. After turning off the active safety assistance system, shift into manual second gear mode. After shifting into manual second gear, gently press the accelerator, and in most cases, the car can be driven out.

What to Do When You Can't See the Road Lines While Driving in Snowy Weather?

Maintain a moderate to low speed and follow the tracks of the vehicle ahead, keeping your speed within a safe range as indicated by information boards and road signs. Keep a safe longitudinal distance from the vehicle in front. In snowy conditions, the following distance should be 2-3 times that of dry road conditions. Shift to a lower gear. When braking is necessary, apply intermittent braking by gently pressing the brake pedal in advance. Avoid slamming the brake pedal all the way down or using the handbrake too abruptly or forcefully. If you're driving on such road conditions, being inflexible and rigidly adhering to the rules is neither appropriate nor safe.

What to Use to Repair Car Light Cracks?

For small cracks in car lights, use glass adhesive for repair. Introduction to Glass Adhesive: Glass adhesive is a material used for bonding and sealing various types of glass with other substrates. It is mainly divided into two categories: silicone adhesive and polyurethane adhesive (PU). Silicone sealant is glass adhesive, which is further divided into acidic and neutral types. Neutral adhesives include: stone sealant, mildew-resistant sealant, fireproof sealant, pipeline sealant, etc. Curing Time of Glass Adhesive: The curing process of silicone adhesive progresses from the surface inward. Different types of silicone adhesives have varying surface drying and curing times, so any surface repairs must be done before the adhesive surface dries (acidic adhesives and neutral transparent adhesives generally within 5-10 minutes, neutral colored adhesives generally within 30 minutes). If masking tape is used to cover an area, it must be removed before the outer layer forms after applying the adhesive.

Is Window Glass Lubricant Actually Useful?

Window lubricant is useful. It is suitable for components such as windows, sunroofs, door hinges, engine hood hinges, electric mirrors, and wipers, providing excellent lubrication for issues like rust, jamming, and abnormal noises. Maintenance-wise: Dashboard wax, also known as instrument wax, is a specialized maintenance product designed for automotive leather trims and instrument panels. It effectively prevents aging of dashboards and interior trims while offering cleaning and anti-static properties as a liquid wax. Lubrication-wise: Window lubricant is suitable for components such as windows, sunroofs, door hinges, engine hood hinges, electric mirrors, and wipers, providing excellent lubrication for issues like rust, jamming, and abnormal noises. To put it simply, high-quality window lubricant is indeed useful. It not only lubricates, reducing friction between rubber seals and window glass to effectively eliminate mechanical noise and resolve issues like window squeaks and jamming, but also provides long-lasting protection for windows. Additionally, it effectively cleans window stains, prevents rubber seal aging and corrosion, restores elasticity, prevents seal leakage, and offers moisture-proof sealing functions.
