Electric Fan?


Recommended Posts

The old fan has three wires, because the AIRCON speeds the fan up when it switches. It isnt for cooling the water for the engine, its purely to pull enough flow through the RAD and the AIRCON CONDENSER RAD together.

Your new fans have only one speed, therefore you may find your aircon wont be as good.

When you wire it up, you MUST make sure the wires used are connected to the temp switch in the rad, so the best way is connect the black wire up to your new fans, then unplug the temp sender connector on the bottom of the rad, bridge the wires and find out which one (green or yellow) feeds the fan. The other one will be live when aircon is on.

you can attach the green and yellow wires to a two position relay if you want so the fan will come on with Aircon, but to be honest the fans are only going to run at one speed.

Also no temp switch in rad, controlled by Ecu I believe.

your ecu may control the fan by the temp sender in the block (just below the intake manifold in the middle at the front.)

Id check to make sure, but sounds like thats right.

However, if it were mine, i would make up an adapter and fit the temp sender in the pipework to the rad. Id much rather the fans run when the water is not being cooled at the rad than it getting too hot at the engine!!!
