What Causes a Car's Cooling Fan to Stop Working?
2 Answers
Car cooling fan failure may be caused by a clogged air filter, insufficient coolant, or a blocked heater core. It could also result from relay malfunctions or issues with the temperature control switch. Relevant information about the car radiator is as follows: 1. Introduction: The car radiator typically refers to the heat exchanger (automotive radiator). As part of the vehicle's cooling system, the engine's water cooling system radiator consists of three main components: the inlet chamber, outlet chamber, main plate, and radiator core. 2. Installation Methods: Radiators can be installed in three configurations: same-side inlet and outlet, opposite-side inlet and outlet, or bottom inlet and bottom outlet. Regardless of the method, it's essential to minimize the number of pipe fittings, as more fittings not only increase costs but also potential risks.
When the cooling fan isn't working, I estimate the most common causes are either a burnt-out fan motor or a blown fuse. It could be due to prolonged driving causing the motor to overheat and wear out, or the fuse acting as protection by automatically cutting off current during circuit abnormalities. Another frequent issue is poor wiring connections, such as loose plugs or aged wires, preventing electricity from reaching the fan. A malfunctioning temperature sensor might also trick the fan into thinking it doesn't need to operate. Engine overheating is extremely dangerous—I remember in summer, if the fan stops working, the engine temperature can spike rapidly, potentially causing severe damage or even spontaneous combustion. If you notice the fan isn't spinning, first park the car safely and avoid driving further. Try checking the fuse box in the engine compartment or the fan's wiring connections. If you're unsure, call a mechanic immediately—safety comes first. Regular maintenance should include attention to the cooling system, and keeping the fan area clean can help prevent issues.
