Second rad fan not working?

[jonnyw]

Fitted my new Radtec ally radiator last night with its two big fans. It really is a work of art.

On the run fantastic 70 c temp.

Got home and tested the fans, only one coming on, at about 95c?

I had the old non-air con single fan before, but I have two terminals for the two fans so assumed that they would both work?

Am I missing something that I have to do elswhere or should they be connected already?

If not, can I draw enough current through the single terminal to run both fans or will they run at half speed?

The second fan comes on at 104c, iirc, or is automatically switched on when you use aircon (if fitted).

The second fan is the passenger side one. Is it possible that your primary fan is keeping the egine sufficiently cool for it not to be needed?

Ah! Ha! 104c, yes the primary fan is keeping it below 100, and yes it is the one wired in on the passenger side. Sounds promising, thanks John

104, are you sure??? The ECU turns one on at 95C and the other at 97C (air con fan).

erm first fan (passenger side one, the larger of the two) on at 92C and also on the aircon .. second (smaller) fan on at 94C ish.

How old are you? I suppose it makes the time pass quicker until you get your car back
