On many vehicles, there may be two fans: a main cooling fan for the radiator, and a second fan for the condenser. Both fans should come on when the A/C is on.
What are the two kinds of fans in a car?
Generally, there are two main categories of mechanical fans – flex fans and clutch fans.
Should both fans run constantly?
It can be normal for the cooling fans to run constantly under certain conditions. If the car is hot enough, they may be barely keeping up with demand and stay on. Also, most cars will run the fans at a high speed if the A/C is turned on.
What are the two kinds of fans in a car?
Generally, there are two main categories of mechanical fans – flex fans and clutch fans.
Which fan is the radiator fan?
The car radiator fan is found between the engine and the radiator, although some radiator fans are found at the front or anterior part of the radiator. Electric fans are found in the front part of the radiator and are also referred to as “pusher fans”.
Is clutch fan or electric fan better?
Clutch fans are the right choice for stock or mildly modified engines. They will adequately cool the engine. Just be sure to use the fan and clutch designed for your application. Using the wrong parts could result in poor cooling, excessive noise, reduced fuel economy, and/or fan clutch failure.
Does radiator fan come on with AC?
The condenser fan (if it has a dedicated fan) or the radiator fan most always comes in (with AC on) when the compressor discharge pressure (or, alternatively, the liquid line one; look for where a sensor or a switch is located on the high pressure line) rises over an operative threshold.
Can you drive with one radiator fan not working?
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.
When should the radiator fan turn on?
What are the two types of radiators?
There are two types of radiators: downflow and upflow.
What type of cooling fans are commonly found in vehicles?
There are two types of cooling fans, mechanically driven and electric fans. Mechanically driven fans are driven by the engines serpentine belt through the water pump while electric fans are driven by an electric motor that is powered by the engine's electrical system.
How many fans does a radiator have?
A lot of vehicles will actually have two radiator fans. One, both or neither may be running at any given time depending on the conditions. When you are cruising at highway speeds, the air rushing over the radiator and around the engine will help control the heat.
What is condenser fan?
A condenser fan is a type of fan that, as the name suggests, is found near the condenser. It's designed to remove heat from the refrigerant inside of the condenser's hollow passages. When running your AC system, refrigerant will pick up heat from inside of your home at the evaporator coil.
What are the two kinds of fans in a car?
Generally, there are two main categories of mechanical fans – flex fans and clutch fans.
How many cooling fans does a car have?
The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. On many vehicles, there may be two fans: a main cooling fan for the radiator, and a second fan for the condenser.
How can I tell if my radiator fan is working?
A simple way to check if the radiator fan is working is to start your engine and turn the air-conditioning system (A/C) to the maximum speed. If the fan is spinning, then it means that the fan motor, fuse, wiring, and relay are all working properly.
Does electric fan save gas?
In a normal pickup situation, even in high ambient temperatures, the electric fan system will only draw a maximum of about 5 horsepower from the engine. This significant savings improves fuel economy, and, in turn, reduces emissions while improving vehicle performance.
What does a clutch fan do?
A fan clutch is a thermostatic engine cooling fan that can freewheel at low temperatures when cooling is not needed, allowing the engine to warm up faster, relieving unnecessary load on the engine. As temperatures increase, the clutch engages so that the fan is driven by engine power and moves air to cool the engine.
What does an electric fan do in a car?
The radiator fan (or fans) pulls cooling air through the car's radiator. Positioned between the radiator and engine, cooling fans are particularly helpful when the car is stationary or moving at speeds too slow to force air through the grille.
Do radiator fans run all the time?
Radiator fans are temperature controlled. They cut in and out to maintain the engine temperature at the optimum level where maximum efficiency is reached. Usually, the radiator fan will not start up the moment you fire up your engine.
What does a broken radiator fan sound like?
When the radiator cooling fan motor begins to fail, it can emit a whirring sound or loud clicking. These sounds can also occur if one of the fan blades becomes damaged and starts touching other components. If you are hearing sounds, at least you know the fan is still working, even minimally.
How much does it cost to replace a 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.
What sensor controls the radiator fan?
On most modern cars, the cooling fan is controlled by the Engine Control Unit (ECU) which gets a signal from the coolant temperature sensor.
How do I know if my radiator is steam or hot water?
The simplest way to tell is to look at the number of pipes coming from your radiator: if there is only one pipe, then it is a steam system. Two pipes could indicate either steam or hot-water, with the condensed or cooled water returning to the boiler from the second pipe.
How many radiators does a car have?
There are two primary car radiators to be aware of… Cross flow radiators, which are designed to use tanks (found on the sides of the radiator core) to enable the coolant to cycle back and forth across the core. As a result, heat can be dissipated across a spacious area.
How much is it to replace a car radiator?
If it turns out that your radiator has damage such as holes or cracks, the whole radiator must be replaced. In this case, the price will vary depending on your car and model, with an average price of $700. The price could exceed $1000 but it may also be as low as $300.
