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.
What happens when a radiator fan stops working? It will cause a loud whirring noise and a stuck open thermostat (which will not allow the engine to reach the average operating temperature). A lousy radiator cooling fan could cause a blown circuit fuse, a malfunctioning relay, and engine overheating.
What can cause a radiator fan to break?
Blown Fuse
Most modern vehicles make use of an electric car radiator fan that starts up once a certain engine temperature is reached. Sometimes, when the electric motor begins to wear out, has failed or has issues with bad wiring, the fuse that controls the fan relay will blow out.
A faulty radiator fan can cause many problems. These are some of the most common: Engine overheating: A bad radiator fan can cause the engine to overheat, especially at low speeds. If your car starts overheating, pull off the road as quickly as you safely can and turn off the engine.
Can I drive with a broken radiator fan? – Related Questions
How can I tell if my radiator fan is working?
How to check a radiator fan
Your check engine light may come on.
There may be steam coming from the hood.
The car simply won’t keep driving anymore once it gets too hot.
If your car has a temperature gauge, then this will also indicate a jump in temperature.
Do radiator fans affect AC?
These fans are necessary to move a sufficient amount of air through both the radiator and the air conditioning condenser. If one or both fans are not operating correctly, sufficient air flow is not achieved. This is not to be confused with the air flow from your dash vents.
Can a fan cause overheating?
Fans do not cool the air, so air currents flowing over the body must be cooler than your body temperature to cool you down. When indoor air temperatures are hotter than about 95 °F:Fan use may cause your body to gain heat instead of lose it.
Why is my car overheating when the coolant is full?
However, if your car is overheating but the coolant is full, it is probably not a leak. Instead, it may be that it’s having trouble circulating correctly. This can stem from several things, including a faulty water pump, a radiator blockage, a stuck thermostat, or a plugged heater core.
What are the common problems that leads for overheating?
Common reasons for overheating engines
Too little or no coolant. Driving without proper levels of coolant/antifreeze may cause a coolant system failure.
Cooling system leaks.
A broken water pump.
Radiator issues.
Oil too low.
Thermostat failure.
Issues with the belts and hoses.
Heater core is plugged up.
How much does it cost to fix a broken radiator fan?
As one of the more expensive car repairs needed (not including the replacement of a seized car engine, obviously), the replacement of the radiator coolant fan could incur about $128 to $162 in labor costs and around $465 in parts. So, total radiator fan replacement cost could be anywhere from $592 to $627.
How long do radiator fans usually last?
In most cases, a properly maintained radiator fan will last between eight and ten years. When the radiator fan fails, it should be replaced as soon as possible. This is because without a cooling fan to help remove heat from the engine, your car is more likely to overheat and cause damage to important engine components.
How long can you drive a car without a radiator fan?
In short it is dangerous for engine-time depends on thermostate heater,,in hot weather it take 2-3 minutes but in cold weather it take 10-15 mints for upshoot engine heat… better to switch off the car.
How long does it take to replace a radiator fan?
It can take an experienced mechanic about two to three hours to replace it, depending on the type of vehicle and assembly. In most cases, the radiator fan only needs to be replaced if it starts failing, but if it does start to fail, it is an essential repair.
The cooling fan is also known as a radiator fan because it’s mounted directly to the radiator in some engine layout. Typically, the fan is positioned between the radiator and engine as it draws heat to the atmosphere. In front-wheel cars, the cooling fan used is an electrical component powered by the battery.
How do you test a radiator cooling fan?
When should radiator fan come on?
Most fans should come on, when the coolant reaches, about 200 to 230 degrees.
Does thermostat turn on radiator fan?
The thermostat found in the cooling system will control many of the electric fans. When a certain preset temperature has been reached by the car engine, the radiator fan will begin to cool the engine. The fan will turn off eventually if the temperature goes below the preset engine temperature.
