Nissan S15 Thermo Fan Setup « omgpham… - The factory ac thermo fan has the main characteristic to quiet down the ac condenser, but it follows positive situations which are controlled via the european/ecm. Whilst the eu detects that the ac is grew to become on, it sends out a trigger to show on the fan, however if vehicle speed is detected to be above 40km/h then the fan is disabled until the car slows down below 40km/h. That is a completely critical characteristic due to the fact if the condenser isn't always cool, the ac might not be cold and the condenser can attain high pressures and explode!!!.

I did a number of research and determined to go with the twin thermo fanatics from the ford falcon au. They're designed to be run at dual speeds, and also come with a very good fan shroud that suits up with many radiators. For controlling duties i decided at the dakota digital fan controller, it has the capacity to cause two fan speeds and may be very clean to setup and install.

Alrighty now, under is the wiring diagram i drew up. I can not take complete credit as it's based totally on a few diagrams i have seen on the interwebs. Basically the two fans are run in series @ 6v each for low mode, and they are run in parallel @ 12v for high mode. The dakota fan controller is used to display coolant temperatures after which trigger the precise relays whilst the temperature switching factors are reached. I additionally determined to add an additional relay which disconnects the battery from the circuit whilst the auto is cranking, it's simply a further precaution to boom battery life.

So i determined to attract up my very own diagram, i spent a piece of time drawing it and i suppose it'll paintings however if anyone who is aware of a chunk about car electrics can check it to make certain its all true to move.

With all that during thoughts, i set out to design and put in force a thermo fan setup that could paintings perfectly in my s15. To me, this meant it needed to be neat, green, and hold the function/features of the manufacturing facility ac thermo fan (which could be eliminated along side the grasp a laugh).
