Hello sir can help me of my sedan car nissan exalta 2003 model of it suddenly stop the engine its like overheating but the temp is in half? And the blowet is working.
Sorry, you'll need to see a mechanic, we can't diagnose problems over the internet, there could be a number of things wrong.
Great helpful video! One question, how do you wire the fan system to turn on when you turn on the A/C?
Thanks! Since each system is different, we suggest getting in contact with the manufacturer if it's an aftermarket system, like Vintage Air. They can make sure you have a trinary switch instead of a binary switch to control electric cooling fans, and can advise you on which wire to use to trigger the relay.
For a factory A/C where you likely have only one wire to the compressor - you will need to wire in a second relay to trigger the cooling fan relay, because the OE style usually has a single wire that is +12 volts to trigger the compressor. Using a second relay will allow you to convert the signal to create a ground trigger, which you could connect to the gray wire.

looking on their website they are proud of their stuff by looking at the prices. I spent $17.00 for a relay kit, and they sell one just like the one I got for. $74.95 .
Flunk'em
Cheap relays might not have a diode fitted to prevent voltage spikes when relay is switched off. FLYBACK DIODE.
Stupid question, what if you want your vehicle to run around average temp around 190? Is what temp the fan kicks on adjustable? From what I read your offerings kick on at 185 and off at 165???
You can buy a sender with different range from Summit, just make sure it's an on/off switch, not a variable switch: 0-300º.

What guage of wire to be use. And to to connect to thermo switch with a two way connector
to be used where? For the fan circuit: typically 12g or 10g, for the relay switching circuit: 16g or 14g, for the sender 16g is fine.
What temperature is the switch and what temperature thermostat should be used?
As stated in the video, our switch will turn on at about 185º, and off at about 170º, but you can get switches with varying temperatures. As for the thermostat, that's individual preference based on the engine and location, but typically between 168º and 195º.
Do you have video on how to wire dual fans?
It's just like this video; add another relay and wire it the same way: both gray wires together, both orange wires together, red to second fan, yellow to battery with its own fuse.
@@ChampionCoolingSystems thank you!
I want to install a switch because my electric fans sometimes come on before I restart my car, and it strains the battery a lot. If I do it this way, will turning it off with the switch cause it to be off no matter what?
Essentially I want to wire a kill switch to my electric fan.
If you wire it correctly, the fan will always go off when you shut the engine off with the ignition switch. If you turn off the key and the fan still works, it's not wired properly.
A bypass switch is an option, some use it for A/C or very hot days, but the temp sender will still turn the fans on at about 185º regardless of the bypass switch.
Hi, if i want to make the fan kick in when the ac on, is it safe if i connect compressor wire to trigger relay?
Hi- It all depends on the A/C system, if the compressor is triggered by a positive lead (compressor clutch is grounded) or if you have a two wire lead to the compressor (where one is the ground wire). If it's an aftermarket A/C, please contact the manufacturer and they can best guide you on how and where to connect the wires. For instance, with Vintage Air, you'll need a Trinary switch, and they can assist you with that and help determine what is in your system already. For a factory system with a single wire to activate the A/C, you'll need to install an additional relay, as our fan relays are triggered by a ground connection at the sending unit.
Whats the number on the relay for those color wires ??
Not sure what you mean about the number? Do you mean part number?
@@ChampionCoolingSystems sorry the number of which color wire is plugged in im starting from scratch i only have red blk blue yellow
For example gray one is 85 ground ?
@@stranger1907 Sorry, didn't see your reply. This video is for our specific relay kit, and the wires are sealed and the schematic is for our system.
For aftermarket relays, this would be the standard wiring configuration: 30 - battery+; 87 - accessory; 86 - +12v switched; 85 - ground. Since I'm not familiar with your specific relay and wiring, I can't tell you which wire would go to which circuit.
Do I need to drill a hole for it to be mounted in the intake manifold? I bought this kit for a Ford ranger, doing an e fan conversion
I wouldn't drill any holes in the intake, most areas are too thin to install a sender. If you don't have an additional port, we have an article that might have some ideas for you:

@@ChampionCoolingSystems thanks, I have one of those T fittings and a few hose clamps coming and hopefully it'll work, but im pretty sure I'll have to connect it to a ground.
@@imnottellinudontwannaknow3188 Using our sender, since it's a 1-wire sender, it should ground to the fittings and intake. If you use a thread sealer, use it sparingly - too much and your sender won't be able to get a ground connection. Most fittings are tapered (NPT) and will seal pretty tight.
What amp alternator would you recommend for a dual fan setup?
There's a process to figure out what you'll need by adding things up, such as audio (amplifiers) and other electrical items that have been added. For just adding dual fans, consider they may add 20-40 amps, so if you have a 60 amp alternator you might want to look into getting something 80-100 amps. There are lots of one-wire alternators these days that will have an internal regulator and are very simple to connect.
ChampionCooling The factory provided a 60amp. I upgraded to a 100 but i also have efi and a new fuel pump. Im thinking 100 is not going to be enough. I see it charging at 14.2 often but I dont think it can keep up because if i drive it all day the battery goes dead.
@@Campbase1 Sorry, for some reason YT didn't notify me of your message. The basic rule of thumb is to add up all of your components: Fans, audio, EFI, Fuel Pump and try to install an alternator that is close to or a little higher. My car survived on a 100 amp alternator for a couple years, easily, with these components. Just make sure your charge wire is large enough (minimum 8g). While the car is running, put your hand on the wire... (try it when there isn't residual heat from the engine) ... if the wire is warm, it's probably best to go a little bit larger to a 6g wire. If the wire is cool to the touch, it's fine.
ChampionCooling thank you. As i recall, they replied some time ago. Its working perfectly at this time. I have a 100 amp installed. I think some of my heating problem was related to engine timing. Thanks again
If my sensor wire is a double wire, can I still just clip off the sensor and add a loop terminal to then attach to the top of the temp sender i have installed?
Not really sure what you're describing there. Our sensor is an "on-off" switch, whereas most sensors are variable. A variable sensor will not work properly because on that type of sensor only provides a solid ground connection at full temp (about 250º). Our sensor provides a closed connection at 180-185º, and opens at about 175º. On a double-wire sensor, one wire is a constant ground connection and the other is to a load (like a gauge), and cutting the wrong wire would render the sender function inoperable. Additionally, our sender will not work at all with a gauge, as it would send the gauge to read 250º as soon as it closes at 185º. This video describes the different sensors: ruclips.net/video/tN2cGiz1wcQ/видео.html
I can connect the gray wire to the thermo switch of my car.
Hello- you can only connect the gray wire to the thermo switch that came with our relay kit, they're different switches. Ours is on-off, the one in the car is variable.
Which website is yours? Champion radiator or champion cooling
We are Champion Cooling. Champion Radiators is one of our dealers, they are independent, not us. thanks
Can I use the starter post for the ignition wire?
Hi David - I wouldn't. That's a constant hot, and you don't want the fan on all the time.
Awesome
Why didn't you explain which terminals that the wires connect to on the relay, which is 1 of the most important pieces of the puzzle?, lol
Because this video is for installation of Champion Cooling relays, which are pre-wired; they're "plug and play" - so all you need to do is connect the wires as shown in the video. If you want to see how the relay and temperature switch function, that's a separate video. Thanks for your input.
