How To Install Electric Cooling Fan

How To Install Electric Cooling Fan – Electric Fans and Car Wiring On another page we did a little work on the transmitter and another on the horn, now here is some information about the electric cooling fan and how to safely lay the wires. These are mainly wiring, repairs, racing cars, etc. for cars without. If you have an electric fan, most of the hard work is done. The image above is an example of different styles of electric fans (some not to scale). Fan wiring diagrams start from the simplest to the most complex, so you can adapt them. Adding Electric Fans This is really the highlight of the page here. Editing is left as an exercise for the reader (remember school!). You don’t need a lot of tools, but a good cable puller and a basic tool in your mechanic’s toolbox. Parts you may need beyond wiring (both ultra high current style and fine relay control), automotive relays, circuit breakers, temperature control switches or the now popular high tech style electronic controllers. There are some basic electrical rules to follow right from the start on an electric fan line, but it’s pretty easy. Before you start, here are some important tips – Use the correct size cable for your system Use a circuit breaker to prevent your car (or truck) from catching fire in the event of a short circuit. For the moving part of a fan or motor. Protect wires from chafing and shorting (see fuse explanation above) Make sure all electrical connections are neat, clean and tight.

Common Automotive Fan Relays Above are some common relays that can be found in automotive application. An important part to keep in mind is how much your ventilation system is currently consuming. A single 10-inch fan can draw anywhere from 5 to 20 amps! If you are using two fans, note the fuse size, gearing and cable capacity are more important. The leftmost relay is a standard Bosch style relay. Look for a good quality 40 amp version (not the cheap 20 amp one pictured). It is the most common and easy to install. The central relay is designed for high current fan systems. The relay is rated for 70 amps and has a screwdriver which can take some work to get right. However, the small amount of extra work is well worth it as this relay will not cause much trouble in most fan systems. I like the configuration and installation of this relay. I chose one that I use in my car – a Tyco 70 Amp Relay. They are a little more expensive, but they are a quality part and have a lot more capacity, which is good for fans as they are more durable in relays. The right relay is a 70 amp cubic style. I’m not a big fan of them because the main power plants are different and not easily accessible. They work well and fit in a small area, but they aren’t big fans (understand). Plenty of other places have them on Amazon, but you have to make sure the 2 terminals are the FAT lug style, not the 70 amp style. Prices are higher than Tyco relays. NOTE: Some relays are prewired. If the cable gauge is not stamped on the cable, or if the cable gauge is suspected to be a cheap cable connector, you can check. If you can’t get a high quality switch to match a high quality relay, it’s best to make your own. Play it safe and double check what you are using.

Manual 2-speed fan control If you look at what’s going on, I’d say it’s not a 2-speed fan, but actually a two-stage fan, or two fans at full speed. You’re right, but I’m not sure if anyone understood the “2-level speed control” idea. In any case, this is a slightly complicated scheme. The idea in this case is a switch that can be controlled in case one or both fans are not working. This is done with 2 relays with the appropriate amperage. The small triangle facing the switch is the DIODE. This prevents current from flowing in one direction and allows it to flow in the other direction. This part costs about 25 cents (you can use parts 1N4001 to 1N4007). With a few modifications, this circuit can replace the 12 volt source part with the ground part of the circuit (ask me if you need it, I can install and post) if you have a SPDT Center Off switch, it’s there. 3 positions. Left, center and right. In the central position, there is no affiliation to any party and both supporters are closed. If you complete the circuit to the bottom section of the relay, only the right fan will turn on. If you plug into the top of the switch, both relays will activate and both fans will turn on.

Above – Some fuse solutions for fans. When designing fuses or circuit breakers, you have several options. the only option

All that’s left is the Maxi-Fuse inner cable. It is recommended! Clean thick cable, waterproof case

Make these cute and inexpensive built-in fuse holders. Maxi-Fuses can be rated from 20 to 100 Amps, perfect for you

The center is an ATO/ATC style fuse, a normal car next to a Maxi-fuse. You can use the ATO style (

Appropriate range holders) for low amperage fuses. As you can probably guess, I like Maxi-Fuse. Is different

The most accurate is a reasonable choice of automatic reset circuit breaker. I’m not really interested in automation.

Part of it, but if you’re short on time, fix the problem without replacing anything. Disadvantages

They turn on and off (slow delay) until the issue is resolved. These are found in different streams.

If the fan is rated at 10 amps, this is the current it will normally run at. In the beginning, fans can download more boosters.

Margin. For most fans you will want to start with a 20 amp fuse. Works with fans in the 10 to 12 Amp range

And keep things safe. Typically a good starting point above that is 50% more than the amps on the fuse, then rounded up.

For example, if you are using an 18 A fan, add 9 A to get 27 A (i.e. 50% more). Their number is 27

The auxiliary fuse is rounded to 30 Amps. If more than one fan is running and one of them is shorted, it’s best to connect them individually.

At least you still have seconds running. When in doubt, consult the manufacturer’s website, which usually offers some

Speaking of fuses, it’s also important to make sure you use wire that’s thick enough for the high power connection. 150 240 Degree Radiator Cooling Fan Relay Kit Thermostat Temperature Switch Automobile Mounting Accessory Electric Cooling Fan Wire Harness Kit

To the fans. The transmission carries very little current, but the fan is a pig. Use a wire size calculator to get an approximate size.

In all cases, I wouldn’t use less than 14 gauge for the smallest fan. Wired, bigger, thicker is better.

Simple Fan Relay Wiring The figure above shows a simple and straightforward fan wiring diagram. It can support one or two fans and use a simple relay circuit to connect them. A switch can turn the fan on or off manually. If you use temperature switches you can use it to turn on when the engine reaches a set temperature. Often, but not always, these temperature switches are the only terminals that go to the engine block or bodywork radiator, usually both based on older cars. Some newer cars may have a two terminal temperature switch, in which case one goes to the relay and the other to ground. The “12 volt fuse” cable is like the ignition switch that energizes the switch when it is turned on. On some cars, it plugs into an always-on (still plugged-in) source, so the car cools even after the lock is off. Make sure you know that in this scenario you are losing and you could end up dead in weird situations. Some vehicles have a delay that overrides this feature.
