Yes, you can drive your car without a radiator fan, but you never should. Your vehicle’s cooling system is crucial to its performance, and every time your engine overheats, you cause damage. Too much damage equals a repair bill you don’t ever want to see in your lifetime, which is why Kirk’s Auto Care services and repairs cooling systems.
Why Say Yes If You’re Just Going to Say No
Sorry if our answer is a bit frustrating but it’s both a technical and logical response. Yes, technically your engine does not need a cooling fan to operate. Logically, however, the cooling fan keeps the cooling system at the optimal temperature to prevent the hotter than normal engine temperatures, as mentioned above. As such, you should never drive your vehicle if the cooling fan isn’t working even though you can. It’s crucial to maintain ideal operating conditions.
The only exception to this rule would be if you are driving in the middle of an infamous Livonia, MI, winter and you can keep rolling at all times. Bear in mind, without the radiator fan the only way to draw cool air through your vehicle’s grille and into the engine is by motion. If the radiator does not have cool air blowing on it constantly, it will overheat eventually, so you’d need the perfect combination of weather and traffic to drive effectively without a radiator fan.
Don’t Do It Anyway
Perfect weather-traffic combination aside, we still don’t recommend you drive without a radiator fan. Radiator fans operate in two different ways depending on the year, make, and model of your automobile. Some fans are part of the crankshaft or water pump, which means they turn all the time. Other fans are controlled by the vehicle’s electrical system, and they turn on when the engine is idling and cool air isn’t blowing through the grille.
The latter, which is found in most cars, is thermostat controlled. If they don’t come on – well, you know what’ll happen. Aside from your radiator spewing coolant all over the place, the other common concern of an overheated engine is your head gasket. Engines that run too hot can crack the gasket, and this is an expensive repair – a thousands-of-dollars expensive repair. So ask yourself this question: Is it worth it to drive a car without a radiator fan. Nope. It’s not.
