How To Wire An Electric Radiator Fan Relay Temp Sensor AND Switch! | @WiringRescue

This video shows how to easily wire an electric radiator fan circuit into any car. This fan wiring diagram includes a fan relay, a temperature switch, and a manual on/of switch that can be used to manually turn on the fan whenever you want. This radiator fan wiring circuit is great when building a hotrod, muscle car, or anytime that you're swapping from a clutch fan to an electric fan.

The Electric Radiator Fan Relay Wiring:
- Pin 30 (Red) 12v input from battery through circuit breaker
- Pin 86 (Black) 12v power feed from ignition switch
- Pin 87 (Red) 12v relay output sending power to the fan
- Pin 85 (Brown) Ground, goes to temperature switch and on/of switch
- Pin 87A Not Used

Thank You for Watching my Electric Radiator Fan Wiring video! 

[eugeneeeee]

I’ve never watched a more put together and professional video on this topic

[nicknick]

This vid should be taught in schools, it’s perfect

[corygoins]

Working on vehicles all my life, I’ve never imagined a complete circuit laid out on a board. It’s pretty neat. Thanks for a perfectly explained video.

[hugoortiz]

If more people explained wiring like this, a lot less people would be intimidated by electrical circuits on their vehicle.

After having my radiator fan bust up my radiator after breaking off its mount I am upgrading from a pulley fan to an electric fan while I replace my radiator and this was exactly what I needed to help make sure I had not missed anything when installing it. Amazing work, helping people out even a year later!

3 years ago my truck caught fire because of a pretty bad wiring work. I decided not to give up on her and worked hard to bring her back to life... and I succeeded mechanically speaking. However, I had been always scared of dealing with electricity and wires because nobody was patient enough to explain things to me like if I was a 5 yes old kid... that was until I found your channel. Thanks to you I was not only able to completely wire my rig - rock crawler - but I have now understood the reasons behind every connection... Honestly, I cannot find the proper words which can emphasize my deep appreciation and gratitude to you... Thank you for sharing your knowledge...

[jeremyorndorff]

Honestly I appreciate your professionalism and clarity on explaining this 'HOW-TO!!" After watching this video, I have no idea how anyone can mess it up. THANK YOU🤘🤘

[jasonthibodeaux]

This is EXACTLY what I needed to know! You're a great teacher! Keep those videos coming, my friend!

[tgjames]

Best explanation on YouTube, hands down. Thanks!!

[boatboattmmrp]

I’ve struggled for years to understand electrical, and you finally made it all click. I feel like most other resources out there dump too much info at once on you and don’t explain the how very well.

[adamscott]

Fantastic video! Great diagram and thorough explanation of everything. I’ve watched 4-5 videos on the subject and was still lost. 1 play through of this and I’m confident in my new knowledge. Great job!

[DreamKeeper.]

I’d love to see a video done for gauges like oil, Temperature, volts, and RPMs

[cokerart]

THANK YOU!!!
You have explained how to accomplish this in layman's terms, without making me (us) feel stupid. Bravo!

[jeffcobb]

I agree with last comment. Been up till 6am searching for info on the override switch and here it is! WOW!Now I can sleep til 2PM get up CMA and go to work.
Thanks! Great clear to the point video😃

I was doing a random search on the electrical side of the cooling system and found your excellent presentation as I was about to give up. Needless to say, I've subscribed. Because you've not only clarified a suspicion I had, you've also taught me enough to go through the circuit in a logical way. So from the bottom of my heart, thank you!!

[Ismail-wwub]

Best video of an simulation on a cooling fan system I've ever seen.

[CostlyFiddle]

Awesome demonstration! I am not watching to gain the knowledge for automotive reasons (although now I know), instead I am searching for a clever no-solder solution to the always on tiny 24v cooling fan for the hotend of my 3D Printer. Your simple explanation of how relay circuits work really helped in figuring out the different hardware, how they interact, & how to wire it WITH A BYPASS to boot! Thanks again! 😊

[kanenstuff]

This is what I miss since I have moved abroad people with skills that know what they are on about. I won't say where I live but most of the electricians here can't even read a drawing they should watch your channel and learn I will do this myself after watching this cheers.

Your wiring videos are the best on the web. Simple and elegant.
