Frequently Asked Questions (FAQs)

1. Can you add an electric fan to a radiator?

Yes, adding an auxiliary electric fan to the front of the radiator can help overcome the problem of insufficient air movement through the radiator. This can prevent the engine from running hot or overheating in certain applications.

2. What are the three types of cooling fan systems?

The three types of cooling fan systems are clutch fans, flex fans, and electric fans. Clutch fans have fixed blades and require a coupler to engage and disengage the fan. Flex fans do not need a clutch and have blades that flatten out at high RPM. Electric fans are driven by a dedicated electrical motor instead of the engine.

3. What are the two main types of auxiliary coolers?

The two main types of auxiliary coolers are "tube-and-fin" coolers and "stacked plate" coolers. The tube-and-fin cooler is the most common type, while the stacked plate cooler is another option.

4. Do electric radiator fans push or pull air?

Electric radiator fans can either push air through the radiator or pull air through it. A pusher fan is positioned in front of the radiator and may obstruct airflow when the vehicle is moving. A puller fan sits right behind the radiator and is typically preferred.

5. Where should electric fans be placed on radiators?

Electric fans should generally be placed on the engine side of the radiator, preferably as a pull fan. This placement ensures that the fan does not interfere with airflow at highway speeds.

6. Can you run two fans on one relay?

Running two fans on one relay can be inefficient and potentially dangerous. The load in amps at startup for dual fans may blow the fuse for a single relay, typically around 30 amps. This setup may not provide enough support for both fans engaging simultaneously.

7. Is a 3 or 4 blade fan better for cooling faster?

A 4-blade fan is generally less noisy and can be useful in rooms with an air conditioner to circulate cool air. However, a 3-blade fan may move air faster than a 4-blade fan and can be a more cost-effective option.
