Having fitted an aftermarket electric fan ( I know they're deemed unnecessary given the rad cooling capacity but I have to negotiate mega traffic queues on occasion) - anyway - the instructions indicate that the fan should be fitted engine side of the rad BUT that the airflow is from the engine bay out into the world. Surely this is wrong. It means the fan is fighting against any airflow caused by moving forward.......... Advice?? I am tempted to reverse the polarity and have the fan sucking air into the engine bay.

Of course the fan must suck air IN if you have fitted it engine side.

Yes, I had to do that when I fitted a Kenlowe. Reversed the polarity to make it suck from the engine side.

I then joined the wires with spade connectors on one wire and bullets on the other, to ensure I got the polarity right every time in future.

And me too to all of the above. So much tidier having the fan in front of the rad. Same with the "un-mixable" connectors. No chance of getting it wrong even if you try hard.
Cheers, Colin.

Some fan blades are designed to work properly only in one direction of rotation - so reversing polarity and spinning it the 'wrong' way is not necessarily the thing to do...
