listy Posted February 12, 2013 Share Posted February 12, 2013 Is this a viable option? The viscous fan really dates the engine bay IMO and would love to ditch it. I also want to keep the stock rad, so would make brackets for the fans. Afaik, the stock ecu can't run the fans, so is there any way of doing it without the being on all the time? Or is that the only option without getting an aftermarket ecu? Quote Link to comment Share on other sites More sharing options...
scott87 Posted February 12, 2013 Share Posted February 12, 2013 Could you not wire them a live feed from a 12v somewhere and then tap into the sensor that tells the Viscous fan when to come on and run this as a switch for the new electric fans? (Although afaik my fan seems to just be on when the engine is) Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 12, 2013 Share Posted February 12, 2013 A viscous fan doesn't have a sensor that switches it on http://www.pistonheads.com/gassing/topic.asp?t=930740 Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 12, 2013 Share Posted February 12, 2013 Kenlowe electric fans have a temp sensor you plumb into the water system usually on the inlet to the rad and it has its own thermostat you adjust to when the fans come on and off Don't SRD's or Whifbitz kits have this kind of set up ?

scott87 Posted February 12, 2013 Share Posted February 12, 2013 A viscous fan doesn't have a sensor that switches it on http://www.pistonheads.com/gassing/topic.asp?t=930740 So its not possible to take anything reading wise from when the clutch engages? Never had a Viscous fan before. In my mr2 i simply unplugged the engine temp sensor and wired a switch in so that i could turn it on and off as i pleased. I would imagine you could do the same and just have them on a switch although thats not the best option. Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 12, 2013 Share Posted February 12, 2013 Yes you use the water temp to tell the fans when to come on and off, manually operating them really isn't a good idea Quote Link to comment Share on other sites More sharing options...
Guest Budz86 Posted February 12, 2013 Share Posted February 12, 2013 The SRD one can come with the thermostat controller if needed Quote Link to comment Share on other sites More sharing options...
Shane Posted February 12, 2013 Share Posted February 12, 2013 I used one of these on mine, worked but was never happy with the seal it provided in the top hose http://www.ebay.co.uk/itm/Variable-Thermostat-Tempature-Control-Kit-Radiator-Cooling-Fans-/390539066336?pt=UK_CarsParts_Vehicles_CarParts_SM&hash=item5aedf13be0 So I then used one of these in conjuction with a fan sensor switch from something else, MX5 I think, with something like this: http://www.ebay.co.uk/itm/Alloy-Water-Temp-Gauge-Radiator-Hose-Sensor-Adaptor-Temperature-Select-Size-/290674684498?pt=LH_DefaultDomain_3&var=&hash=item43ad8fb252 The sensor controls a relay that in turn controls the fans. I am going to make a variation on this when I get time that will switch in the fans and control their speeds according to the need. Quote Link to comment Share on other sites More sharing options...
Dnk Posted February 12, 2013 Share Posted February 12, 2013 This is one on a Kenlowe system, i had this type on my comp safari Range Rover. Worked a treat and nice and simple Quote Link to comment Share on other sites More sharing options...

Rob_Mitchell Posted February 12, 2013 Share Posted February 12, 2013 SRD fans are kenlowe electric fans. The stock fan does look dated but its by far the best at cooling and doing its job. Quote Link to comment Share on other sites More sharing options...

Swampy442 Posted February 12, 2013 Share Posted February 12, 2013 You just have to look at the amount of air a stock fan compared to electric ones. Quote Link to comment Share on other sites More sharing options...
listy Posted February 12, 2013 Author Share Posted February 12, 2013 Thanks for the input guys. So, if I got electric fans, I'd just need a temp sensor plumbed into the (top) rad pipe? and a relay, and this will tell the fans when to come on. Would it be best to power it through the ignition?

Its up to you, some cars that have electric fans are hard wired and continue to run even when the ignition is off, for me though I prefer not to hear them whirring away as I walk away from the car.
