Chris, I have been watching all of your videos over the last year and have throughly enjoyed and appreciated all of them. I am currently also just finishing up with building my own 1970 Chevelle SS. The car has been the dream of my life and now that I am older and retired, it was finally time last year to start building my dream car. All of your videos ave been amazingly timely, helpful and just the information I needed in each step of my build. I just finished installing a brand new, not rebuilt, Chevrolet/edelbrock 454 engine. Last month I was installing the gauges on the pillar and this weekend I am looking at putting different speeds and fuses on my fans. Thanks for all the great information you provide all of us car builders and especially 1970 Chevelle builders.

put in new cts an new 180 t stat.on ac both fans come on high , cools down very well, to hot on regulator heater at 217 cuts on an to hot , hard for fans to cool it back down. very good demo for wiring thermo controls, this motor is fine when running cooler , on ac max is 196, cools down in time an fine.

Good point about the Schematics that come with the parts, Being (given) that the Electrical part is 12 VDC for a car , The Amps are most critical that are being used by the load. Don’t assume just because the Fan is made for cars that your system won’t burn up with out the correct protection. Very easy to overlook

Helpful video, I have a question. When I comes to the thermostat do you need to find one that matches the BMW switch or it doesn't matter. My switch it 180/195 and my thermostat opens up at 80 degrees Celsius.

Hi Chris! Thanks for the great videos. I watched Part 1 and connected the fans as you instructed. I also used this video to incorporate an AC bypass, but I got it wrong somehow. How do you add a bypass for the AC for a two fan set up with fans connected in series? I appreciate any help you can provide. Thanks again!

Hey Chris...I posted on your other video a question..98 lincoln town car 4.6...I removed the A/C compressor and installed a pulley bypass...now a/c compressor disconnected so no pressure in the a.c. lines..which makes high pressure and low pressure switches not functioning...problem is electric cooling fan runs all the time even with ignition off...which drains the battery. Any thoughts how to remedy the situation...Thanks

Just FYI, not all 2 speed BMW coolant temp switches are the same. Some kick the auxillary fan on at 196°/210°F (91/99°C) while the earlier switches, back in the 80's I believe, kicked the fan on at 176°/192°F (81/89°C). Know which one your system needs or you could make things worse. BMW sensors are rated in Celsius. If the parts person cant tell you what their sensors open/close at, dont buy it till they can.

Hello Chris. i'm planning to convert my trailblazer 2006 clutch fan to an electric fan. But i need to know some points in your video which i believed it could help me. 1) Video frame 4:49. Are both the switches (180 and 190) will be closed once it reached 190? 2) or the 180 will switch to open and only the 190 will close? 3) Video frame 5:20, the schematic tells me that the high speed fan will always works when ac is on? would it be better if the fan will only works when ac pressure reached 180 psi and will shuts off at 179 psi and below? do you have some idea what ac pressure switch to use which will turns close at 180 psi? my point is that i want the fans to turns off when i'm running 60 to 100 kph.

Thanks so.much for the informative video. I will have to source out the thermostats which will take some time. Right now my 2 80watts aux fans are killing my battery. I tapped both replays in the AC Compressor positive wire which turns on both fans when my AC is turned on. I was planning to temporarily add a 12v 3A/260VAC push switch to turn off fan at night since AC is cold without the fans. Will that switch suffice or do I have to get a 20A push switch? TIA

... isnt it that the alternator isnt charging your batteries quickly? Low idle charge? Im installing a 150amp to try and charge my battery while pulling a 100 amps. The 150 is capable of powring 100a at idle speeds, so its rated. We will see.

Great video!!!! Couple of questions though. When you splice in the ac circuit to the hot side of the temp switch, what makes the low speed fan come on? Also, when you reach high temp on that switch, won't it turn the AC compressor on, as there is no diode to direct current flow?

@@chriscraft77022 It may work but that is not correct and may cause future problems. Electricity takes the easiest path of resistance and the power from the 190 degree trigger will go to the ac. It may not be enough to turn on the compressor but there is power going in that direction. A diode is recommended and some relays have a trigger wire with a diode for AC and other components to trigger the relays.

Also, can I use my GM swithches instead of the BMW? I really liked the running the fans in series and would like to run that setup. unfortunately my car is the old style that did not have high, just medium speed. Thanks again for your videos!

The AC bypass is incorrect. DON'T connect it that way!!! If you do, your AC system will stay on continuously when the temperature is above 190 degrees or whatever your second temperature is on the BMW switch. Power will come from the ignition through the BMW switch and power up your AC compressor keeping it running non-stop until it overheats and craps out. Ask me how I know!!! You need to use a trinary switch to turn your fans on and off and allow the compressor to cycle on and off when it needs to based on the internal ac pressure.
