M325is 0 Report post Posted December 21, 2006 So my viscous doesnt work and a new one is a bit beyond my budget at the mo so I got myself a 12" cooling fan that I can switch on an off over the summer. My question is... It doesnt really fit behind the radiator so infront it must be, or is there a better way of going about it? Anybody fitted one before, tips on which button to wire it to??? Sooner the answer the better if there is a more effective way as the mounts are being made tomorrow. Thanks in advance Quote Share this post Link to post Share on other sites
kerrynzl 3 Report post Posted December 21, 2006 Front works fine [as long as the fan is turning the right direction] Try and fit a temperature switch from a jappa [heaven forbid] into the cooling system [prefer lower radiator] wire it in series from the ignition to the fan to the switch to earth [you can also parrallel wire a manual override switch in as well] Most Temp/switches have a 20degree overlap between switching on and off [don't use Mazda,as you'll need a reverse pole relay] Quote Share this post Link to post Share on other sites
