mr_s Posted December 28, 2010 Share Posted December 28, 2010 Hi, I'm going to be fitting a kenlowe (or similar but cheaper!) adjustabl thermostat/fan to my RRC, what temperature should I set the fan to come on at? What's factory spec for the viscous fan to start working to it's full potential? I'm sure once I've got a Haynes book I'll stop with the inane questions Cheers, Martin Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted December 28, 2010 Share Posted December 28, 2010 With the risk of sounding a touch rude, do a search, please, this has been covered dozens of times in the past, but the crux of it is find some twin Mondeo fans, and buy an X-fan switch from X-Eng and job done.

paintman Posted December 28, 2010 Share Posted December 28, 2010 Having tried both on the same car 3.5 EFi LPG RRC(no, not at the same time!) - genuine twin Kenlowe & original factory fit viscous - I wouldn't bother again. With the kenlowe's I noticed NO difference in fuel consumption and NO difference in warm-up from cold. There was a reduction in noise from under the bonnet, but not noticable in the car. Main advantage would be to anyone who frequently deep wades, you can turn the fan off & avoid throwing water over the engine. Quote Link to comment Share on other sites More sharing options...
mr_s Posted January 1, 2011 Author Share Posted January 1, 2011 Thanks for the info - I did do a search but couldn't find anything relating to the actual temperature to operate the fan at. Had a look at the x-eng website and that did seem to answer the question - (fan on at 88, off at 83 or on at 92 and off at 87 deg c if anyone is searching in the future ). Paintman - yeah, I wasn't expecting much in the way of increased performance or economy, I mostly want it for wading, and for space under the bonnet!

elbekko Posted January 1, 2011 Share Posted January 1, 2011 With the kenlowe's I noticed NO difference in fuel consumption and NO difference in warm-up from cold. It still has to get its power from somewhere, and in the electric fans' case that's the alternator, so the engine will still be supplying it, just via a detour. If anything, I'd expect it to be less efficient, unless you have it turned off most of the time. Quote Link to comment Share on other sites More sharing options...
